一、新建工程，添加ibatis、spring和struts的jars；
二、数据库设计.
mysql数据库：
Sql代码
use ibatis;
drop table if exists user;
create table if not exists user(
ID tinyint primary key auto_increment,
LOGIN_NAME varchar(10) not null,
PASS_WORD varchar(15) not null,
QX varchar(10) default 'guest' not null ,
MEMO text
)
type=innodb
comment="user info";
insert into user(LOGIN_NAME,PASS_WORD,QX) values('leh','888','admin');
insert into user(LOGIN_NAME,PASS_WORD) values('lek','888');
commit;
[sql] view
plaincopy
use ibatis;
drop table if exists user;
create table if not exists user(
ID tinyint primary key auto_increment,
LOGIN_NAME varchar(10) not null,
PASS_WORD varchar(15) not null,
QX varchar(10) default 'guest' not null ,
MEMO text
)
type=innodb
comment="user info";
insert into user(LOGIN_NAME,PASS_WORD,QX) values('leh','888','admin');
insert into user(LOGIN_NAME,PASS_WORD) values('lek','888');
commit;
数据源的配置
1）、配置文件db.properties （位置：resources/properties/db.properties，这里resources和src是一类文件）
Xml代码
driver=com.mysql.jdbc.Driver
url=jdbc\:mysql\://localhost\:3306/ibatis
username=root
password=54321
[xml] view
plaincopy
driver=com.mysql.jdbc.Driver
url=jdbc\:mysql\://localhost\:3306/ibatis
username=root
password=54321
2）、注册数据源到spring
Xml代码
!-- spring load dataSource configuration property file -->
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>properties/database.properties</value>
</list>
</property>
</bean>
<!-- dataSource -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="${driver}" />
<property name="url" value="${url}" />
<property name="username" value="${username}" />
<property name="password" value="${password}" />
</bean>
[xml] view
plaincopy
!-- spring load dataSource configuration property file -->
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>properties/database.properties</value>
</list>
</property>
</bean>
<!-- dataSource -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="${driver}" />
<property name="url" value="${url}" />
<property name="username" value="${username}" />
<property name="password" value="${password}" />
</bean>
三、POJO类.
本例是User实例类：
Java代码
package com.leadtone.ibatis.domain;
import java.io.Serializable;
public class User implements Serializable{
private int id;
private String name;
private String password;
private String qx;
private String memo;
public int getId() {
return id;
}
/**
*setter和getter方法省略
*/
[java] view
plaincopy
package com.leadtone.ibatis.domain;
import java.io.Serializable;
public class User implements Serializable{
private int id;
private String name;
private String password;
private String qx;
private String memo;
public int getId() {
return id;
}
/**
*setter和getter方法省略
*/
四、pojo类配置文件编写
本例是User.xml:(位置：com.leadtone.sqlmap.User.xml)
Xml代码
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMap
PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN"
"http://ibatis.apache.org/dtd/sql-map-2.dtd">
<sqlMap namespace="User">
<typeAlias alias="user" type="com.leadtone.ibatis.domain.User"/>
<resultMap class="user" id="UserResult">
<result property="id" column="ID"/>
<result property="name" column="LOGIN_NAME"/>
<result property="password" column="PASS_WORD"/>
<result property="qx" column="QX"/>
<result property="memo" column="MEMO"/>
</resultMap>
<!-- query all Users -->
<select id="selectAllUsers" resultMap="UserResult">
select * from user
</select>
<!-- query user by id -->
<select id="selectUserById" parameterClass="int" resultMap="UserResult">
select ID,LOGIN_NAME,PASS_WORD,QX,MEMO from user where ID=#id#
</select>
<!-- query user by user -->
<select id="selectUserByUser2" parameterClass="map" resultMap="UserResult">
select ID,LOGIN_NAME,PASS_WORD,QX,MEMO
from user
<dynamic prepend="where">
<isNotEmpty prepend="and" property="name">
LOGIN_NAME=#name#
</isNotEmpty>
<isNotEmpty prepend="and" property="password">
PASS_WORD=#password#
</isNotEmpty>
</dynamic>
</select>
<select id="selectUserByUser" parameterClass="user" resultMap="UserResult">
select ID,LOGIN_NAME,PASS_WORD,QX,MEMO
from user
<dynamic prepend="where">
<isNotEmpty prepend="and" property="name">
LOGIN_NAME=#name#
</isNotEmpty>
<isNotEmpty prepend="and" property="password">
PASS_WORD=#password#
</isNotEmpty>
</dynamic>
</select>
<select id="selectUsersByName" parameterClass="String" resultMap="UserResult">
select ID,LOGIN_NAME,PASS_WORD,QX,MEMO
from user
<dynamic prepend="where">
<isNotEmpty prepend="and" property="value">
sname like '%$value$%'
</isNotEmpty>
</dynamic>
</select>
<!--
<insert id="addUser" parameterClass="User">
insert into user(LOGIN_NAME,PASS_WORD,QX,MEMO )
values(#name#,#birth#,#score#)
<selectKey keyProperty="id" resultClass="int">
select last_insert_id()
</selectKey>
</insert>
<!-- 注意这里的keyProperty="id" 中的id就是User中的id属性，resultClass就是查询的的返回值 -->
-->
<update id="updateUser" parameterClass="User">
update user set LOGIN_NAME=#name#,PASS_WORD=#password#,QX=#qx#,memo=#memo# where ID=#id#
</update>
<delete id="deleteUser" parameterClass="int">
delete from user where ID=#id#
</delete>
</sqlMap>
[xml] view
plaincopy
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMap
PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN"
"http://ibatis.apache.org/dtd/sql-map-2.dtd">
<sqlMap namespace="User">
<typeAlias alias="user" type="com.leadtone.ibatis.domain.User"/>
<resultMap class="user" id="UserResult">
<result property="id" column="ID"/>
<result property="name" column="LOGIN_NAME"/>
<result property="password" column="PASS_WORD"/>
<result property="qx" column="QX"/>
<result property="memo" column="MEMO"/>
</resultMap>
<!-- query all Users -->
<select id="selectAllUsers" resultMap="UserResult">
select * from user
</select>
<!-- query user by id -->
<select id="selectUserById" parameterClass="int" resultMap="UserResult">
select ID,LOGIN_NAME,PASS_WORD,QX,MEMO from user where ID=#id#
</select>
<!-- query user by user -->
<select id="selectUserByUser2" parameterClass="map" resultMap="UserResult">
select ID,LOGIN_NAME,PASS_WORD,QX,MEMO
from user
<dynamic prepend="where">
<isNotEmpty prepend="and" property="name">
LOGIN_NAME=#name#
</isNotEmpty>
<isNotEmpty prepend="and" property="password">

</isNotEmpty>
</dynamic>
</select>
<select id="selectUserByUser" parameterClass="user" resultMap="UserResult">

from user
<dynamic prepend="where">
<isNotEmpty prepend="and" property="name">
LOGIN_NAME=#name#
</isNotEmpty>
<isNotEmpty prepend="and" property="password">
PASS_WORD=#password#
</isNotEmpty>
</dynamic>
</select>
<select id="selectUsersByName" parameterClass="String" resultMap="UserResult">
select ID,LOGIN_NAME,PASS_WORD,QX,MEMO
from user
<dynamic prepend="where">
<isNotEmpty prepend="and" property="value">
sname like '%$value$%'
</isNotEmpty>
</dynamic>
</select>
<!--
<insert id="addUser" parameterClass="User">
insert into user(LOGIN_NAME,PASS_WORD,QX,MEMO )
values(#name#,#birth#,#score#)
<selectKey keyProperty="id" resultClass="int">
select last_insert_id()
</selectKey>
</insert>
<!-- 注意这里的keyProperty="id" 中的id就是User中的id属性，resultClass就是查询的的返回值 -->
-->
<update id="updateUser" parameterClass="User">
update user set LOGIN_NAME=#name#,PASS_WORD=#password#,QX=#qx#,memo=#memo# where ID=#id#
</update>
<delete id="deleteUser" parameterClass="int">
delete from user where ID=#id#
</delete>
</sqlMap>
【补充：】动态sql：
一般来说，拼接动态sql是在查询时，指定多个查询条件的情况下用的，所以用到parameterClass= (map或具体类)，
但对于传递过来的参数就一个时，若如下代码就会出错：
Xml代码
<select id="selectUserById" parameterClass="int" resultMap="UserResult">
select sid,sname,smajor,sbirth,score from users
<dynamic prepend="where">
<isNotEmpty prepend="and" property="id">
sid=#id#
</isNotEmpty>
</dynamic>
</select>
[xml] view
plaincopy
<select id="selectUserById" parameterClass="int" resultMap="UserResult">
select sid,sname,smajor,sbirth,score from users
<dynamic prepend="where">
<isNotEmpty prepend="and" property="id">
sid=#id#
</isNotEmpty>
</dynamic>
</select>
会报错误如下：There is no READABLE property named 'id' in class 'java.lang.Integer'
因为你无缘故用了一个莫名其妙的property="id",id对ibatis来说不认识。
这时的解决办法有两种，一个是这里的property="id" 中的id用value来代替，所以下面的sid=#value#，这个value是ibatis内部指定个变量；另一个方法是直接把property="id"删除，不用property这个属性了。
五、ibatis主配置文件编写【主配置文件只剩下sqlMap了，事务和数据源都交给spring进行配置和管理】
本例为sql-map-config.xml:(位置：)
Xml代码
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMapConfig
PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"
"<A href="http://ibatis.apache.org/dtd/sql-map-config-2.dtd">http://ibatis.apache.org/dtd/sql-map-config-2.dtd</A>">
<sqlMapConfig>
<sqlMap resource="com/leadtone/ibatis/sqlmap/User.xml"/>
<!--
<sqlMap resource="com/leadtone/ibatis/sqlmap/User1.xml"/>
<sqlMap resource="com/leadtone/ibatis/sqlmap/User2.xml"/>
<sqlMap resource="com/leadtone/ibatis/sqlmap/Usern.xml"/>
-->
</sqlMapConfig>
[xml] view
plaincopy
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMapConfig
PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"
"<a href="http://ibatis.apache.org/dtd/sql-map-config-2.dtd">http://ibatis.apache.org/dtd/sql-map-config-2.dtd</a>">
<sqlMapConfig>
<sqlMap resource="com/leadtone/ibatis/sqlmap/User.xml"/>
<!--
<sqlMap resource="com/leadtone/ibatis/sqlmap/User1.xml"/>
<sqlMap resource="com/leadtone/ibatis/sqlmap/User2.xml"/>
<sqlMap resource="com/leadtone/ibatis/sqlmap/Usern.xml"/>
-->
</sqlMapConfig>
六、dao接口和接口实现
1）、本例为UserDao：
Java代码
package com.leadtone.ibatis.dao;
import java.util.List;
import com.leadtone.ibatis.domain.User;
public interface IUserDao {
public List<User> queryAllUsers();
public User queryUserById(int id);
public User queryUserByUser(User user);
public List<User> queryUserByName(String name);
public void addUser(User user);
public void addUserBySequence(User user);
public void updateUser(User user);
public void deleteUser(int id);
}
[java] view
plaincopy
package com.leadtone.ibatis.dao;
import java.util.List;
import com.leadtone.ibatis.domain.User;
public interface IUserDao {
public List<User> queryAllUsers();
public User queryUserById(int id);
public User queryUserByUser(User user);
public List<User> queryUserByName(String name);
public void addUser(User user);
public void addUserBySequence(User user);
public void updateUser(User user);
public void deleteUser(int id);
}
2）、实现类UserDaoImpl：
Java代码
package com.leadtone.ibatis.dao.ibatis;
import java.util.List;
import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;
import com.leadtone.ibatis.dao.IUserDao;
import com.leadtone.ibatis.domain.User;
public class UserDaoImpl extends SqlMapClientDaoSupport implements IUserDao {
//注意这里的SqlMapClient接口的声明和下面的static静态代码都不需要了，
// 因为这里继承了spring提供的ibatis模板template类SqlMapClientDaoSupport，不是用原生的SqlMapClient
//private static SqlMapClient sqlMapClient=null;
/*
static{
Reader reader=null;
try {
reader=Resources.getResourceAsReader("com/leadtone/ibatis/sqlmap/SqlMapConfig.xml");
sqlMapClient=SqlMapClientBuilder.buildSqlMapClient(reader);
reader.close();
} catch (IOException e) {
e.printStackTrace();
}
}
*/
public void addUser(User user) {
getSqlMapClientTemplate().insert("addUser", user);
}
public User queryUserByUser(User user) {
System.out.println("---UserDaoImpl---");
return (User) this.getSqlMapClientTemplate().queryForObject("selectUserByUser", user);
}
/*
* 这里主要演示一个模拟用户登录系统验证的操作，主要用了queryUserByUser(User user)方法
*/
}
[java] view
plaincopy
package com.leadtone.ibatis.dao.ibatis;
import java.util.List;
import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;
import com.leadtone.ibatis.dao.IUserDao;
import com.leadtone.ibatis.domain.User;
public class UserDaoImpl extends SqlMapClientDaoSupport implements IUserDao {
//注意这里的SqlMapClient接口的声明和下面的static静态代码都不需要了，
// 因为这里继承了spring提供的ibatis模板template类SqlMapClientDaoSupport，不是用原生的SqlMapClient
//private static SqlMapClient sqlMapClient=null;
/*
static{
Reader reader=null;
try {
reader=Resources.getResourceAsReader("com/leadtone/ibatis/sqlmap/SqlMapConfig.xml");
sqlMapClient=SqlMapClientBuilder.buildSqlMapClient(reader);
reader.close();
} catch (IOException e) {
e.printStackTrace();
}
}
*/
public void addUser(User user) {
getSqlMapClientTemplate().insert("addUser", user);
}
public User queryUserByUser(User user) {
System.out.println("---UserDaoImpl---");
return (User) this.getSqlMapClientTemplate().queryForObject("selectUserByUser", user);
}
/*
* 这里主要演示一个模拟用户登录系统验证的操作，主要用了queryUserByUser(User user)方法
*/
}
3）、在spring配置文件中配置这个bean
Xml代码
<!--sqlMapClient -->
<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
<property name="configLocation" value="sqlmap/sql-map-config.xml"/>
<property name="dataSource" ref="dataSource" />
</bean>
<!-- validate loginUser -->
<!-- dao -->
<bean id="userDao" class="com.leadtone.ibatis.dao.ibatis.UserDaoImpl">
<property name="sqlMapClient" ref="<SPAN style="COLOR: #000000">sqlMapClient </SPAN>"></property>
</bean>
[xml] view
plaincopy
<!--sqlMapClient -->
<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
<property name="configLocation" value="sqlmap/sql-map-config.xml"/>
<property name="dataSource" ref="dataSource" />
</bean>
<!-- validate loginUser -->
<!-- dao -->
<bean id="userDao" class="com.leadtone.ibatis.dao.ibatis.UserDaoImpl">
<property name="sqlMapClient" ref="<span style="color:#000000;">sqlMapClient </span>"></property>
</bean>
七、service接口和接口实现
1）IUserLoginService接口
Java代码
package com.leadtone.ibatis.service;
import com.leadtone.ibatis.domain.User;
public interface IUserLoginService {
public boolean isLoginUser(User user);
}
[java] view
plaincopy
package com.leadtone.ibatis.service;
import com.leadtone.ibatis.domain.User;
public interface IUserLoginService {
public boolean isLoginUser(User user);
}
2）UserLoginSerivceImpl实现类
Java代码
package com.leadtone.ibatis.service.impl;
import com.leadtone.ibatis.dao.IUserDao;
import com.leadtone.ibatis.domain.User;
import com.leadtone.ibatis.service.IUserLoginService;
public class UserLoginServiceImpl implements IUserLoginService {
private IUserDao userDao;
public IUserDao getUserDao() {
return userDao;
}
public void setUserDao(IUserDao userDao) {
this.userDao = userDao;
}
public boolean isLoginUser(User user) {
return null!=userDao.queryUserByUser(user)?true:false;
}
}
[java] view
plaincopy
package com.leadtone.ibatis.service.impl;
import com.leadtone.ibatis.dao.IUserDao;
import com.leadtone.ibatis.domain.User;
import com.leadtone.ibatis.service.IUserLoginService;
public class UserLoginServiceImpl implements IUserLoginService {
private IUserDao userDao;
public IUserDao getUserDao() {
return userDao;
}
public void setUserDao(IUserDao userDao) {
this.userDao = userDao;
}
public boolean isLoginUser(User user) {
return null!=userDao.queryUserByUser(user)?true:false;
}
}
3）在spring中注册这个bean
Xml代码
<!-- service -->
<bean id="userLoginService" class="com.leadtone.ibatis.service.impl.UserLoginServiceImpl">
<property name="userDao" ref="userDao"></property>
</bean>
[xml] view
plaincopy
<!-- service -->
<bean id="userLoginService" class="com.leadtone.ibatis.service.impl.UserLoginServiceImpl">
<property name="userDao" ref="userDao"></property>
</bean>
八、struts action实现及struts-config.xml配置(牵扯到struts和spring的整合)
1）action：
Java代码
package com.leadtone.web.struts.action;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import com.leadtone.ibatis.domain.User;
import com.leadtone.ibatis.service.IUserLoginService;
import com.leadtone.web.struts.form.LoginForm;
public class LoginAction extends Action {
private IUserLoginService userLoginService;
public IUserLoginService getUserLoginService() {
return userLoginService;
}
public void setUserLoginService(IUserLoginService userLoginService) {
this.userLoginService = userLoginService;
}
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
LoginForm loginForm = (LoginForm) form;
String name=loginForm.getUsername();
String password=loginForm.getPassword();
User user=new User();
user.setName(name);
user.setPassword(password);
boolean isLogin=false;
isLogin = userLoginService.isLoginUser(user);
System.out.println(isLogin);
if(isLogin){
request.setAttribute("username", name);
return mapping.findForward("success");
}
else
return mapping.findForward("failure");
}
}
[java] view
plaincopy
package com.leadtone.web.struts.action;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import com.leadtone.ibatis.domain.User;
import com.leadtone.ibatis.service.IUserLoginService;
import com.leadtone.web.struts.form.LoginForm;
public class LoginAction extends Action {
private IUserLoginService userLoginService;
public IUserLoginService getUserLoginService() {
return userLoginService;
}
public void setUserLoginService(IUserLoginService userLoginService) {
this.userLoginService = userLoginService;
}
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
LoginForm loginForm = (LoginForm) form;
String name=loginForm.getUsername();
String password=loginForm.getPassword();
User user=new User();
user.setName(name);
user.setPassword(password);
boolean isLogin=false;
isLogin = userLoginService.isLoginUser(user);
System.out.println(isLogin);
if(isLogin){
request.setAttribute("username", name);
return mapping.findForward("success");
}
else
return mapping.findForward("failure");
}
}
2）actionForm:
Java代码
public class LoginForm extends ActionForm {
private String username;
private String password;
private String grade;
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
return null;
}
public void reset(ActionMapping mapping, HttpServletRequest request) {
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getGrade() {
return grade;
}
public void setGrade(String grade) {
this.grade = grade;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
}
[java] view
plaincopy
public class LoginForm extends ActionForm {
private String username;
private String password;
private String grade;
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
return null;
}
public void reset(ActionMapping mapping, HttpServletRequest request) {
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getGrade() {
return grade;
}
public void setGrade(String grade) {
this.grade = grade;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
}
3）xml：
Xml代码
<struts-config>
<data-sources />
<form-beans >
<form-bean name="loginForm" type="com.leadtone.web.struts.form.LoginForm" />
</form-beans>
<global-exceptions />

<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
<set-property property="contextConfigLocation" value="classpath:applicationContext.xml" />
</plug-in>
</struts-config>
4）页面：

九、spring配置文件的内容【牵扯到ibatis和struts的整合】
Xml代码
<!-- action -->
<bean name="/login" class="com.leadtone.web.struts.action.LoginAction" abstract="false"
lazy-init="default" autowire="default" dependency-check="default">
<property name="userLoginService" ref="userLoginService"></property>
</bean>
[xml] view
plaincopy
<!-- action -->
<bean name="/login" class="com.leadtone.web.struts.action.LoginAction" abstract="false"
lazy-init="default" autowire="default" dependency-check="default">
<property name="userLoginService" ref="userLoginService"></property>
</bean>
十、测试
这里的测试 包括单元测试。例如对dao层、service层、action层编写完成后都要进行junit4单元测试（Jmock或easyMock等）测试，这里就不添加了。
另外补充一点：
就是spring的配置文件中对事物拦截器的配置，也是必须的，这里没有配置，有兴趣的可以搜索一下添加上。

二、数据库设计.
三、POJO类.
四、pojo类配置文件编写
五、ibatis主配置文件编写【主配置文件只剩下sqlMap了】
六、dao接口和接口实现
七、service接口和接口实现
八、struts action实现及struts-config.xml配置
九、spring配置文件的内容【牵扯到ibatis和struts的整合】
十、测试
一、新建工程，添加ibatis、spring和struts的jars；
二、数据库设计.
mysql数据库：
Sql代码
use ibatis;
drop table if exists user;
create table if not exists user(
ID tinyint primary key auto_increment,
LOGIN_NAME varchar(10) not null,
PASS_WORD varchar(15) not null,
QX varchar(10) default 'guest' not null ,
MEMO text
)
type=innodb
comment="user info";
insert into user(LOGIN_NAME,PASS_WORD,QX) values('leh','888','admin');
insert into user(LOGIN_NAME,PASS_WORD) values('lek','888');
commit;
[sql] view
plaincopy
use ibatis;
drop table if exists user;
create table if not exists user(
ID tinyint primary key auto_increment,
LOGIN_NAME varchar(10) not null,
PASS_WORD varchar(15) not null,
QX varchar(10) default 'guest' not null ,
MEMO text
)
type=innodb
comment="user info";
insert into user(LOGIN_NAME,PASS_WORD,QX) values('leh','888','admin');
insert into user(LOGIN_NAME,PASS_WORD) values('lek','888');
commit;
数据源的配置
1）、配置文件db.properties （位置：resources/properties/db.properties，这里resources和src是一类文件）
Xml代码
driver=com.mysql.jdbc.Driver
url=jdbc\:mysql\://localhost\:3306/ibatis
username=root
password=54321
[xml] view
plaincopy
driver=com.mysql.jdbc.Driver
url=jdbc\:mysql\://localhost\:3306/ibatis
username=root
password=54321
2）、注册数据源到spring
Xml代码
!-- spring load dataSource configuration property file -->
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>properties/database.properties</value>
</list>
</property>
</bean>
<!-- dataSource -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="${driver}" />
<property name="url" value="${url}" />
<property name="username" value="${username}" />
<property name="password" value="${password}" />
</bean>
[xml] view
plaincopy
!-- spring load dataSource configuration property file -->
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>properties/database.properties</value>
</list>
</property>
</bean>
<!-- dataSource -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="${driver}" />
<property name="url" value="${url}" />
<property name="username" value="${username}" />
<property name="password" value="${password}" />
</bean>
三、POJO类.
本例是User实例类：
Java代码
package com.leadtone.ibatis.domain;
import java.io.Serializable;
public class User implements Serializable{
private int id;
private String name;
private String password;
private String qx;
private String memo;
public int getId() {
return id;
}
/**
*setter和getter方法省略
*/
[java] view
plaincopy
package com.leadtone.ibatis.domain;
import java.io.Serializable;
public class User implements Serializable{
private int id;
private String name;
private String password;
private String qx;
private String memo;
public int getId() {
return id;
}
/**
*setter和getter方法省略
*/
四、pojo类配置文件编写
本例是User.xml:(位置：com.leadtone.sqlmap.User.xml)
Xml代码
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMap
PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN"
"http://ibatis.apache.org/dtd/sql-map-2.dtd">
<sqlMap namespace="User">
<typeAlias alias="user" type="com.leadtone.ibatis.domain.User"/>
<resultMap class="user" id="UserResult">
<result property="id" column="ID"/>
<result property="name" column="LOGIN_NAME"/>
<result property="password" column="PASS_WORD"/>
<result property="qx" column="QX"/>
<result property="memo" column="MEMO"/>
</resultMap>
<!-- query all Users -->
<select id="selectAllUsers" resultMap="UserResult">
select * from user
</select>
<!-- query user by id -->
<select id="selectUserById" parameterClass="int" resultMap="UserResult">
select ID,LOGIN_NAME,PASS_WORD,QX,MEMO from user where ID=#id#
</select>
<!-- query user by user -->
<select id="selectUserByUser2" parameterClass="map" resultMap="UserResult">
select ID,LOGIN_NAME,PASS_WORD,QX,MEMO
from user
<dynamic prepend="where">

</isNotEmpty>
<isNotEmpty prepend="and" property="password">

</isNotEmpty>
</dynamic>
</select>
<select id="selectUserByUser" parameterClass="user" resultMap="UserResult">
select ID,LOGIN_NAME,PASS_WORD,QX,MEMO
from user
<dynamic prepend="where">
<isNotEmpty prepend="and" property="name">

</isNotEmpty>
<isNotEmpty prepend="and" property="password">

</isNotEmpty>
</dynamic>
</select>
<select id="selectUsersByName" parameterClass="String" resultMap="UserResult">
select ID,LOGIN_NAME,PASS_WORD,QX,MEMO
from user
<dynamic prepend="where">
<isNotEmpty prepend="and" property="value">
sname like '%$value$%'
</isNotEmpty>
</dynamic>
</select>
<!--
<insert id="addUser" parameterClass="User">
insert into user(LOGIN_NAME,PASS_WORD,QX,MEMO )
values(#name#,#birth#,#score#)
<selectKey keyProperty="id" resultClass="int">
select last_insert_id()
</selectKey>
</insert>
<!-- 注意这里的keyProperty="id" 中的id就是User中的id属性，resultClass就是查询的的返回值 -->
-->
<update id="updateUser" parameterClass="User">
update user set LOGIN_NAME=#name#,PASS_WORD=#password#,QX=#qx#,memo=#memo# where ID=#id#
</update>
<delete id="deleteUser" parameterClass="int">
delete from user where ID=#id#
</delete>
</sqlMap>
[xml] view
plaincopy
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMap
PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN"
"http://ibatis.apache.org/dtd/sql-map-2.dtd">
<sqlMap namespace="User">
<typeAlias alias="user" type="com.leadtone.ibatis.domain.User"/>
<resultMap class="user" id="UserResult">
<result property="id" column="ID"/>
<result property="name" column="LOGIN_NAME"/>
<result property="password" column="PASS_WORD"/>
<result property="qx" column="QX"/>
<result property="memo" column="MEMO"/>
</resultMap>
<!-- query all Users -->
<select id="selectAllUsers" resultMap="UserResult">

</select>
<!-- query user by id -->
<select id="selectUserById" parameterClass="int" resultMap="UserResult">
select ID,LOGIN_NAME,PASS_WORD,QX,MEMO from user where ID=#id#
</select>
<!-- query user by user -->
<select id="selectUserByUser2" parameterClass="map" resultMap="UserResult">

</isNotEmpty>
</dynamic>
</select>
<select id="selectUsersByName" parameterClass="String" resultMap="UserResult">
select ID,LOGIN_NAME,PASS_WORD,QX,MEMO
from user
<dynamic prepend="where">
<isNotEmpty prepend="and" property="value">
sname like '%$value$%'
</isNotEmpty>
</dynamic>
</select>
<!--
<insert id="addUser" parameterClass="User">
insert into user(LOGIN_NAME,PASS_WORD,QX,MEMO )
values(#name#,#birth#,#score#)
<selectKey keyProperty="id" resultClass="int">
select last_insert_id()
</selectKey>
</insert>
<!-- 注意这里的keyProperty="id" 中的id就是User中的id属性，resultClass就是查询的的返回值 -->
-->
<update id="updateUser" parameterClass="User">
update user set LOGIN_NAME=#name#,PASS_WORD=#password#,QX=#qx#,memo=#memo# where ID=#id#
</update>
<delete id="deleteUser" parameterClass="int">
delete from user where ID=#id#
</delete>
</sqlMap>
【补充：】动态sql：
一般来说，拼接动态sql是在查询时，指定多个查询条件的情况下用的，所以用到parameterClass= (map或具体类)，
但对于传递过来的参数就一个时，若如下代码就会出错：
Xml代码
<select id="selectUserById" parameterClass="int" resultMap="UserResult">
select sid,sname,smajor,sbirth,score from users
<dynamic prepend="where">
<isNotEmpty prepend="and" property="id">
sid=#id#
</isNotEmpty>
</dynamic>
</select>
[xml] view
plaincopy
<select id="selectUserById" parameterClass="int" resultMap="UserResult">
select sid,sname,smajor,sbirth,score from users
<dynamic prepend="where">
<isNotEmpty prepend="and" property="id">
sid=#id#
</isNotEmpty>
</dynamic>
</select>
会报错误如下：There is no READABLE property named 'id' in class 'java.lang.Integer'
因为你无缘故用了一个莫名其妙的property="id",id对ibatis来说不认识。
这时的解决办法有两种，一个是这里的property="id" 中的id用value来代替，所以下面的sid=#value#，这个value是ibatis内部指定个变量；另一个方法是直接把property="id"删除，不用property这个属性了。
五、ibatis主配置文件编写【主配置文件只剩下sqlMap了，事务和数据源都交给spring进行配置和管理】
本例为sql-map-config.xml:(位置：)
Xml代码
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMapConfig
PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"
"<A href="http://ibatis.apache.org/dtd/sql-map-config-2.dtd">http://ibatis.apache.org/dtd/sql-map-config-2.dtd</A>">
<sqlMapConfig>
<sqlMap resource="com/leadtone/ibatis/sqlmap/User.xml"/>
<!--
<sqlMap resource="com/leadtone/ibatis/sqlmap/User1.xml"/>
<sqlMap resource="com/leadtone/ibatis/sqlmap/User2.xml"/>
<sqlMap resource="com/leadtone/ibatis/sqlmap/Usern.xml"/>
-->
</sqlMapConfig>
[xml] view
plaincopy
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMapConfig
PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"
"<a href="http://ibatis.apache.org/dtd/sql-map-config-2.dtd">http://ibatis.apache.org/dtd/sql-map-config-2.dtd</a>">
<sqlMapConfig>
<sqlMap resource="com/leadtone/ibatis/sqlmap/User.xml"/>
<!--
<sqlMap resource="com/leadtone/ibatis/sqlmap/User1.xml"/>
<sqlMap resource="com/leadtone/ibatis/sqlmap/User2.xml"/>
<sqlMap resource="com/leadtone/ibatis/sqlmap/Usern.xml"/>
-->
</sqlMapConfig>
六、dao接口和接口实现
1）、本例为UserDao：
Java代码
package com.leadtone.ibatis.dao;
import java.util.List;
import com.leadtone.ibatis.domain.User;
public interface IUserDao {
public List<User> queryAllUsers();
public User queryUserById(int id);
public User queryUserByUser(User user);
public List<User> queryUserByName(String name);
public void addUser(User user);
public void addUserBySequence(User user);
public void updateUser(User user);
public void deleteUser(int id);
}
[java] view
plaincopy
package com.leadtone.ibatis.dao;
import java.util.List;
import com.leadtone.ibatis.domain.User;
public interface IUserDao {
public List<User> queryAllUsers();
public User queryUserById(int id);
public User queryUserByUser(User user);
public List<User> queryUserByName(String name);
public void addUser(User user);
public void addUserBySequence(User user);
public void updateUser(User user);
public void deleteUser(int id);
}
2）、实现类UserDaoImpl：
Java代码
package com.leadtone.ibatis.dao.ibatis;
import java.util.List;
import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;
import com.leadtone.ibatis.dao.IUserDao;
import com.leadtone.ibatis.domain.User;
public class UserDaoImpl extends SqlMapClientDaoSupport implements IUserDao {
//注意这里的SqlMapClient接口的声明和下面的static静态代码都不需要了，
// 因为这里继承了spring提供的ibatis模板template类SqlMapClientDaoSupport，不是用原生的SqlMapClient
//private static SqlMapClient sqlMapClient=null;
/*
static{
Reader reader=null;
try {
reader=Resources.getResourceAsReader("com/leadtone/ibatis/sqlmap/SqlMapConfig.xml");
sqlMapClient=SqlMapClientBuilder.buildSqlMapClient(reader);
reader.close();
} catch (IOException e) {
e.printStackTrace();
}
}
*/
public void addUser(User user) {
getSqlMapClientTemplate().insert("addUser", user);
}
public User queryUserByUser(User user) {
System.out.println("---UserDaoImpl---");
return (User) this.getSqlMapClientTemplate().queryForObject("selectUserByUser", user);
}
/*
* 这里主要演示一个模拟用户登录系统验证的操作，主要用了queryUserByUser(User user)方法
*/
}
[java] view
plaincopy
package com.leadtone.ibatis.dao.ibatis;
import java.util.List;
import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;
import com.leadtone.ibatis.dao.IUserDao;
import com.leadtone.ibatis.domain.User;
public class UserDaoImpl extends SqlMapClientDaoSupport implements IUserDao {
//注意这里的SqlMapClient接口的声明和下面的static静态代码都不需要了，
// 因为这里继承了spring提供的ibatis模板template类SqlMapClientDaoSupport，不是用原生的SqlMapClient
//private static SqlMapClient sqlMapClient=null;
/*
static{
Reader reader=null;
try {
reader=Resources.getResourceAsReader("com/leadtone/ibatis/sqlmap/SqlMapConfig.xml");
sqlMapClient=SqlMapClientBuilder.buildSqlMapClient(reader);
reader.close();
} catch (IOException e) {
e.printStackTrace();
}
}
*/
public void addUser(User user) {
getSqlMapClientTemplate().insert("addUser", user);
}
public User queryUserByUser(User user) {
System.out.println("---UserDaoImpl---");
return (User) this.getSqlMapClientTemplate().queryForObject("selectUserByUser", user);
}
/*
* 这里主要演示一个模拟用户登录系统验证的操作，主要用了queryUserByUser(User user)方法
*/
}
3）、在spring配置文件中配置这个bean
Xml代码
<!--sqlMapClient -->
<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
<property name="configLocation" value="sqlmap/sql-map-config.xml"/>
<property name="dataSource" ref="dataSource" />
</bean>
<!-- validate loginUser -->
<!-- dao -->
<bean id="userDao" class="com.leadtone.ibatis.dao.ibatis.UserDaoImpl">
<property name="sqlMapClient" ref="<SPAN style="COLOR: #000000">sqlMapClient </SPAN>"></property>
</bean>
[xml] view
plaincopy
<!--sqlMapClient -->
<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
<property name="configLocation" value="sqlmap/sql-map-config.xml"/>
<property name="dataSource" ref="dataSource" />
</bean>
<!-- validate loginUser -->
<!-- dao -->
<bean id="userDao" class="com.leadtone.ibatis.dao.ibatis.UserDaoImpl">
<property name="sqlMapClient" ref="<span style="color:#000000;">sqlMapClient </span>"></property>
</bean>
七、service接口和接口实现
1）IUserLoginService接口
Java代码
package com.leadtone.ibatis.service;
import com.leadtone.ibatis.domain.User;
public interface IUserLoginService {
public boolean isLoginUser(User user);
}
[java] view
plaincopy
package com.leadtone.ibatis.service;
import com.leadtone.ibatis.domain.User;
public interface IUserLoginService {
public boolean isLoginUser(User user);
}
2）UserLoginSerivceImpl实现类
Java代码
package com.leadtone.ibatis.service.impl;
import com.leadtone.ibatis.dao.IUserDao;
import com.leadtone.ibatis.domain.User;
import com.leadtone.ibatis.service.IUserLoginService;
public class UserLoginServiceImpl implements IUserLoginService {
private IUserDao userDao;
public IUserDao getUserDao() {
return userDao;
}
public void setUserDao(IUserDao userDao) {
this.userDao = userDao;
}
public boolean isLoginUser(User user) {
return null!=userDao.queryUserByUser(user)?true:false;
}
}
[java] view
plaincopy
package com.leadtone.ibatis.service.impl;
import com.leadtone.ibatis.dao.IUserDao;
import com.leadtone.ibatis.domain.User;
import com.leadtone.ibatis.service.IUserLoginService;
public class UserLoginServiceImpl implements IUserLoginService {
private IUserDao userDao;
public IUserDao getUserDao() {
return userDao;
}
public void setUserDao(IUserDao userDao) {
this.userDao = userDao;
}
public boolean isLoginUser(User user) {
return null!=userDao.queryUserByUser(user)?true:false;
}
}
3）在spring中注册这个bean
Xml代码
<!-- service -->
<bean id="userLoginService" class="com.leadtone.ibatis.service.impl.UserLoginServiceImpl">
<property name="userDao" ref="userDao"></property>
</bean>
[xml] view
plaincopy
<!-- service -->
<bean id="userLoginService" class="com.leadtone.ibatis.service.impl.UserLoginServiceImpl">
<property name="userDao" ref="userDao"></property>
</bean>
八、struts action实现及struts-config.xml配置(牵扯到struts和spring的整合)
1）action：
Java代码
package com.leadtone.web.struts.action;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import com.leadtone.ibatis.domain.User;
import com.leadtone.ibatis.service.IUserLoginService;
import com.leadtone.web.struts.form.LoginForm;
public class LoginAction extends Action {
private IUserLoginService userLoginService;
public IUserLoginService getUserLoginService() {
return userLoginService;
}
public void setUserLoginService(IUserLoginService userLoginService) {
this.userLoginService = userLoginService;
}
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
LoginForm loginForm = (LoginForm) form;
String name=loginForm.getUsername();
String password=loginForm.getPassword();
User user=new User();
user.setName(name);
user.setPassword(password);
boolean isLogin=false;
isLogin = userLoginService.isLoginUser(user);
System.out.println(isLogin);
if(isLogin){
request.setAttribute("username", name);
return mapping.findForward("success");
}
else
return mapping.findForward("failure");
}
}
[java] view
plaincopy
package com.leadtone.web.struts.action;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import com.leadtone.ibatis.domain.User;
import com.leadtone.ibatis.service.IUserLoginService;
import com.leadtone.web.struts.form.LoginForm;
public class LoginAction extends Action {
private IUserLoginService userLoginService;
public IUserLoginService getUserLoginService() {
return userLoginService;
}
public void setUserLoginService(IUserLoginService userLoginService) {
this.userLoginService = userLoginService;
}
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
LoginForm loginForm = (LoginForm) form;
String name=loginForm.getUsername();
String password=loginForm.getPassword();
User user=new User();
user.setName(name);
user.setPassword(password);
boolean isLogin=false;
isLogin = userLoginService.isLoginUser(user);
System.out.println(isLogin);
if(isLogin){
request.setAttribute("username", name);
return mapping.findForward("success");
}
else
return mapping.findForward("failure");
}
}
2）actionForm:
Java代码
public class LoginForm extends ActionForm {
private String username;
private String password;
private String grade;
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
return null;
}
public void reset(ActionMapping mapping, HttpServletRequest request) {
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getGrade() {
return grade;
}
public void setGrade(String grade) {
this.grade = grade;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
}
[java] view
plaincopy
public class LoginForm extends ActionForm {
private String username;
private String password;
private String grade;
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
return null;
}
public void reset(ActionMapping mapping, HttpServletRequest request) {
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getGrade() {
return grade;
}
public void setGrade(String grade) {
this.grade = grade;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
}
3）xml：
Xml代码
<struts-config>
<data-sources />
<form-beans >
<form-bean name="loginForm" type="com.leadtone.web.struts.form.LoginForm" />
</form-beans>
<global-exceptions />
<global-forwards />

</action>
</action-mappings>
<controller processorClass="org.springframework.web.struts.DelegatingRequestProcessor"></controller>
<message-resources parameter="com.leadtone.web.struts.ApplicationResources" />
<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
<set-property property="contextConfigLocation" value="classpath:applicationContext.xml" />
</plug-in>
</struts-config>
[xml] view
plaincopy
<struts-config>

<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
<set-property property="contextConfigLocation" value="classpath:applicationContext.xml" />
</plug-in>
</struts-config>
4）页面：
login.jsp
Html代码
<body >
<center>
<html:form action="${Pagecontext.request.contextPath}/login" method="post">
<table border="1px" cellspacing="1px" cellpadding="1px" >
<tr>
<td>username : </td>
<td><html:text property="username"/></td>
<td><html:errors property="username"/></td>
</tr>
<tr>
<td>password : </td>
<td><html:password property="password"/></td>
<td><html:errors property="password"/></td>

5)web.xml
Xml代码
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.5" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

<servlet-name>action</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
<init-param>

</web-app>
九、spring配置文件的内容【牵扯到ibatis和struts的整合】
Xml代码
<!-- action -->
<bean name="/login" class="com.leadtone.web.struts.action.LoginAction" abstract="false"
lazy-init="default" autowire="default" dependency-check="default">
<property name="userLoginService" ref="userLoginService"></property>
</bean>
[xml] view
plaincopy
<!-- action -->
<bean name="/login" class="com.leadtone.web.struts.action.LoginAction" abstract="false"
lazy-init="default" autowire="default" dependency-check="default">
<property name="userLoginService" ref="userLoginService"></property>
</bean>
十、测试
这里的测试 包括单元测试。例如对dao层、service层、action层编写完成后都要进行junit4单元测试（Jmock或easyMock等）测试，这里就不添加了。
另外补充一点：
就是spring的配置文件中对事物拦截器的配置，也是必须的，这里没有配置，有兴趣的可以搜索一下添加上。
