主要实现用户的增删改查操作

1、导入相应的jar包







2、配置web.xml主要是配置struts2和spring

web.xml文件内容如下：

[html] view
plaincopy

<?xml version="1.0" encoding="UTF-8"?>

<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<welcome-file-list>

<welcome-file>index.jsp</welcome-file>

</welcome-file-list>

<!-- 加载spring的配置文件 -->

<listener>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

<!-- 配置spring配置文件加载的位置 -->

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:beans.xml</param-value>

</context-param>

<!-- 配置struts2 -->

<filter>

<filter-name>struts2</filter-name>

<filter-class>

org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>

</filter>

<filter-mapping>

<filter-name>struts2</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

</web-app>

3、配置spring配置文件，主要包括配置数据源、事务、mybaits等

beans.xml配置文件详细如下：

[html] view
plaincopy

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:context="http://www.springframework.org/schema/context"

xmlns:aop="http://www.springframework.org/schema/aop"

xmlns:tx="http://www.springframework.org/schema/tx"

xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<!-- 采用注释的方式配置bean -->

<context:annotation-config />

<!-- 配置要扫描的包 -->

<context:component-scan base-package="com.pdsu.edu"></context:component-scan>

<!--proxy-target-class="true"强制使用cglib代理 如果为false则spring会自动选择-->

<aop:aspectj-autoproxy proxy-target-class="true"/>

<!-- 数据库配置文件位置 -->

<context:property-placeholder location="classpath:jdbc.properties" />

<!-- 配置dbcp数据源 -->

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">

<property name="driverClassName" value="${jdbc.driverClassName}" />

<property name="url" value="${jdbc.url}" />

<property name="username" value="${jdbc.username}" />

<property name="password" value="${jdbc.password}" />

<!-- 队列中的最小等待数 -->

<property name="minIdle" value="${jdbc.minIdle}"></property>

<!-- 队列中的最大等待数 -->

<property name="maxIdle" value="${jdbc.maxIdle}"></property>

<!-- 最长等待时间，单位毫秒 -->

<property name="maxWait" value="${jdbc.maxWait}"></property>

<!-- 最大活跃数 -->

<property name="maxActive" value="${jdbc.maxActive}"></property>

<property name="initialSize" value="${jdbc.initialSize}"></property>

</bean>

<!-- 配置mybitasSqlSessionFactoryBean -->

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

<property name="dataSource" ref="dataSource" />

<property name="configLocation" value="classpath:mybatis.xml"></property>

</bean>

<!-- 配置SqlSessionTemplate -->

<bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate">

<constructor-arg name="sqlSessionFactory" ref="sqlSessionFactory" />

</bean>

<!-- 事务配置 -->

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

<property name="dataSource" ref="dataSource" />

</bean>

<!-- 使用annotation注解方式配置事务 -->

<tx:annotation-driven transaction-manager="transactionManager"/>

</beans>

4.JDBC配置文件详细

[plain] view
plaincopy

jdbc.driverClassName=com.mysql.jdbc.Driver

jdbc.url=jdbc:mysql://localhost:3306/operationLog

jdbc.username=root

jdbc.password=

jdbc.maxActive = 2

jdbc.maxIdle =5

jdbc.minIdle=1

jdbc.initialSize =3

jdbc.maxWait =3000

5、配置mybatis主配置文件：

[html] view
plaincopy

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">

<configuration>

<typeAliases>

<typeAlias alias="user" type="com.pdsu.edu.domain.User"/>

</typeAliases>

<mappers>

<mapper resource="com/pdsu/edu/domain/sqlMappers/user.xml" />

</mappers>

</configuration>

6、配置user.xml文件

[html] view
plaincopy

<?xml version="1.0" encoding="utf-8" ?>

<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"

"http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="com.pdsu.edu.domain.User">

<resultMap type="com.pdsu.edu.domain.User" id="userResult">

<result property="id" column="id" jdbcType="INTEGER" javaType="java.lang.Integer" />

<result property="username" column="username" />

<result property="password" column="password" />

</resultMap>

<select id="userLogin" parameterType="user" resultMap="userResult">

select * from user

where

username=#{username} and password=#{password}

</select>

<select id="selectAllUser" resultMap="userResult">

select * from user

</select>

<select id="findUserById" parameterType="int" resultMap="userResult">

select *

from user where id=#{id}

</select>

<insert id="insertUser" parameterType="user">

<![CDATA[

insert into

user(username,password) values(#{username},#{password})

]]>

</insert>

<update id="updateUser" parameterType="user">

update user set

username=#{username},password=#{password} where id=#{id}

</update>

<delete id="deleteUser" parameterType="int">

delete from user where

id=#{id}

</delete>

</mapper>

7、User实体的写法

[java] view
plaincopy

public class User implements Serializable {

private static final long serialVersionUID = -4415990281535582814L;

private Integer id;

private String username;

private String password;

public Integer getId() {

return id;

}

public void setId(Integer id) {

this.id = id;

}

public String getUsername() {

return username;

}

public void setUsername(String username) {

this.username = username;

}

public String getPassword() {

return password;

}

public void setPassword(String password) {

this.password = password;

}

@Override

public String toString() {

return "User [id=" + id + ", password=" + password + ", username=" + username + "]";

}

@Override

public int hashCode() {

final int prime = 31;

int result = 1;

result = prime * result + ((id == null) ? 0 : id.hashCode());

return result;

}

@Override

public boolean equals(Object obj) {

if (this == obj)

return true;

if (obj == null)

return false;

if (getClass() != obj.getClass())

return false;

User other = (User) obj;

if (id == null) {

if (other.id != null)

return false;

} else if (!id.equals(other.id))

return false;

return true;

}

}

8、UserDao的写法

[java] view
plaincopy

public interface UserDao {

public abstract void insertUser(User user);

public abstract void updateUser(User user);

public abstract void deleteUser(Integer userId);

public abstract User findUserByid(Integer userId);

public abstract List<User> findAll();

public abstract User userLogin(User user);

}

9、UserDao的实现

[java] view
plaincopy

@Repository

public class UserDaoImpl implements UserDao {

private final String INSERT_USER = "insertUser";

private final String UPDATE_USER = "updateUser";

private final String DELETE_USER = "deleteUser";

private final String FIND_USER_BYID = "findUserById";

private final String SELECT_ALL_USER = "selectAllUser";

private final String USER_LOGIN = "userLogin";

@Autowired

private SqlSessionTemplate sqlSessionTemplate;

public void insertUser(User user) {

sqlSessionTemplate.insert(INSERT_USER, user);

}

public void updateUser(User user) {

sqlSessionTemplate.update(UPDATE_USER, user);

}

public void deleteUser(Integer userId) {

sqlSessionTemplate.delete(DELETE_USER, userId);

}

public User findUserByid(Integer userId) {

return sqlSessionTemplate.selectOne(FIND_USER_BYID, userId);

}

public List<User> findAll() {

return sqlSessionTemplate.selectList(SELECT_ALL_USER);

}

public User userLogin(User user) {

return sqlSessionTemplate.selectOne(USER_LOGIN, user);

}

}

10、UserService接口

[java] view
plaincopy

public interface UserService {

// 添加用户

public abstract void addUser(User user);

public abstract void updateUser(User user);

public abstract void deleteUser(Integer userId);

public abstract User findUserById(Integer userId);

public abstract List<User> findAllUser();

public abstract User login(User user);

}

11、UserService接口的实现

[java] view
plaincopy

@Service

@Transactional

public class UserServiceImpl implements UserService {

@Autowired

private UserDao userDao;

// 添加用户

public void addUser(User user) {

userDao.insertUser(user);

}

// 更新用户

public void updateUser(User user) {

userDao.updateUser(user);

}

public void deleteUser(Integer userId) {

userDao.deleteUser(userId);

}

public User findUserById(Integer userId) {

return userDao.findUserByid(userId);

}

public List<User> findAllUser() {

return userDao.findAll();

}

public User login(User user) {

return userDao.userLogin(user);

}

}

12、配置Struts2

[html] view
plaincopy

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">

<struts>

<constant name="struts.i18n.encoding" value="UTF-8"/>

<!-- 指定默认编码集 ，作用于HttpServletRequest的setCharacterEncoding（）和freemarker，vilocity的输出 -->

<constant name="struts.configuration.xmlreload" value="true"/>

<!-- 当struts配置文件修改时是否自动加载 -->

<constant name="struts.devMode" value="true"/>

<!-- 开发模式下打印详细的错误信息 -->

<constant name="struts.ui.theme" value="xhtml"/>

<package name="user" namespace="/user" extends="struts-default">

<action name="user_*" class="userAction" method="{1}">

<result name="success" type="redirectAction">user_queryAllUser.action</result>

<result name="input">/index.jsp</result>

<result name="userList">/userList.jsp</result>

<result name="addUser">/userAdd.jsp</result>

<result name="updateUser">/userUpdate.jsp</result>

</action>

</package>

</struts>

13、UserAction具体实现

[java] view
plaincopy

@Controller

@Scope("prototype")

public class UserAction extends ActionSupport {

@Autowired

private UserService userService;

private User user;

private List<User> userList;

public String execute() throws Exception {

return null;

}

public String login() {

if (user != null) {

User user2 = userService.login(user);

if (user2 != null) {

return SUCCESS;

}

}

this.addFieldError("user.username", "用户名或密码错误!");

return INPUT;

}

public String addUI() {

return "addUser";

}

public String updateUI() {

user = userService.findUserById(user.getId());

return "updateUser";

}

public String add() {

userService.addUser(user);

return SUCCESS;

}

public String delete() {

userService.deleteUser(user.getId());

return SUCCESS;

}

public String update() {

userService.updateUser(user);

return SUCCESS;

}

public User getUser() {

return user;

}

public void setUser(User user) {

this.user = user;

}

public String queryAllUser() {

userList = userService.findAllUser();

return "userList";

}

public List<User> getUserList() {

return userList;

}

public void setUserList(List<User> userList) {

this.userList = userList;

}

}

14、登录页面的实现

[html] view
plaincopy

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

<%@ taglib prefix="s" uri="/struts-tags"%>

<%

String path = request.getContextPath();

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

%>
