以简单的用户登录与注册为例.本例中库名为ebusiness表名为tb_user.
需导入Struts和Hibernate相关包文件
第一步: 建库
create database 库名
第二步: 建表
create table 表名
第三步:写对应表字段的Java Bean
//DTO对象Bean
package edu.swk.struts.ebusiness.user;
public class UserBean implements java.io.Serializable{
private int uid;
private String uname;
private String passwd;
private String email;
private String summary;
public void setUid(int uid) {
this.uid = uid;
}
public void setUname(String uname) {
this.uname = uname;
}
public void setPasswd(String passwd) {
this.passwd = passwd;
}
public void setEmail(String email) {
this.email = email;
}
public void setSummary(String summary) {
this.summary = summary;
}
public int getUid() {
return uid;
}
public String getUname() {
return uname;
}
public String getPasswd() {
return passwd;
}
public String getEmail() {
return email;
}
public String getSummary() {
return summary;
}
}
//持久层DTO对象Bean与上面一致
略....
第四步:配置table_name.hbm.xml文件(table_name可自定义,无需一定与表名相同)
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">
<!--在该配置文件中实现tb_user表与TBUser的ORM-->
<hibernate-mapping>
<!--要使用的POJO,及对应的数据库中的表-->
<class name="edu.swk.struts.ebusiness.persist.TBUser" table="tb_user">
<!--声明主键、对应的类型及产生主键的方式-->
<id name="uid" column="uid" type="java.lang.Integer">
<generator class="identity"/>
</id>
<!--表中的其它类型声明-->
<property name="uname" column="uname" type="java.lang.String"/>
<property name="passwd" column="passwd" type="java.lang.String"/>
<property name="email" column="email" type="java.lang.String"/>
<property name="summary" column="summary" type="java.lang.String"/>
</class>
</hibernate-mapping>
第五步:配置hibernate.cfg.xml文件,此文件建立与数据库的连接(驱动、URL、用户名、密码)
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd">
<hibernate-configuration>
<session-factory name="ebusiness">
<property name="hibernate.connection.url">
jdbc:jtds:sqlserver://localhost:1433/ebusiness
</property>
<property name="hibernate.connection.driver_class">
net.sourceforge.jtds.jdbc.Driver
</property>
<property name="hibernate.connection.username">
sa
</property>
<property name="hibernate.connection.password">
sa
</property>
<property name="dialect">
net.sf.hibernate.dialect.SQLServerDialect
</property>
<property name="hibernate.show_sql">
True
</property>
<property name="hibernate.use_outer_join">
True
</property>
<property name="hibernate.transaction.factory_class">
net.sf.hibernate.transaction.JDBCTransactionFactory
</property>
<mapping resource="edu/swk/struts/ebusiness/persist/TBUser.hbm.xml"/>
</session-factory>
</hibernate-configuration>
第六步:JSP页面设计与实现
//主界面
<%@ page contentType="text/html; charset=GBK" %>
<html>
<head>
<title>
index
</title>
</head>
<body bgcolor="#ffffff">
<h1>
选择你要的服务
</h1>
<a href="user/login.jsp">登陆</a><br>
<a href="user/register.jsp">注册</a>
</body>
</html>
//登录界面
<%@ page contentType="text/html; charset=GBK" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
<html>
<head>
<title>
login
</title>
</head>
<body bgcolor="#ffffff">
<h1>
请登陆
</h1>
<html:form action="/login.do">
用户名：<html:text property="uname"/><br />
密码：<html:password property="passwd"/><br />
<html:submit value="登陆"/>
<html:reset/>
</html:form>
</body>
</html>
//注册界面
<%@ page contentType="text/html; charset=GBK" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
<html>
<head>
<title>
register
</title>
</head>
<body bgcolor="#ffffff">
<h1>
用户注册
</h1>
<html:form action="/register.do">
用户名：<html:text property="uname" size="18"/><br />
密码：<html:password property="passwd" size="18"/><br>
确认密码：<html:password property="passwd2" size="18"/><br>
邮箱：<html:text property="email" size="18"/><br>
个人介绍：<html:textarea property="summary" rows="5" cols="28"/><br>
<html:submit value="注册"/>
</html:form>
</html>
第七步:根据JSP表单信息编写Action Form Bean
package edu.swk.struts.ebusiness.user;
import java.io.*;
import javax.servlet.http.*;
import org.apache.struts.action.*;
public class UserForm extends ActionForm{
private int uid;
private String uname;
private String passwd;
private String email;
private String summary;
private String passwd2;
public ActionErrors validate(ActionMapping actionMapping,
HttpServletRequest httpServletRequest) {
/** 根据需要验证表单数据. */
return null;
}
public void reset(ActionMapping actionMapping,
HttpServletRequest servletRequest) {
/** 重置表单数据. */
}
public void setUid(int uid) {
this.uid = uid;
}
public void setUname(String uname) {
this.uname = uname;
}
public void setPasswd(String passwd) {
this.passwd = passwd;
}
public void setEmail(String email) {
this.email = email;
}
public void setSummary(String summary) {
this.summary = summary;
}
public void setPasswd2(String passwd2) {
this.passwd2 = passwd2;
}
public int getUid() {
return uid;
}
public String getUname() {
return uname;
}
public String getPasswd() {
return passwd;
}
public String getEmail() {
return email;
}
public String getSummary() {
return summary;
}
public String getPasswd2() {
return passwd2;
}
}
第八步:持久层的实现
package edu.swk.struts.ebusiness.persist;
import net.sf.hibernate.*;
import net.sf.hibernate.cfg.*;
import org.apache.log4j.Logger;
import java.util.List;
import edu.swk.struts.ebusiness.user.UserBean;
public class UserPersist {
private Session session;
private static Logger logger = Logger.getLogger(UserPersist.class);
/**
* 获得Hibernate环境，并取得session实例
* @throws HibernateException
*/
public UserPersist()throws PersistException{
logger.info("开始进行Hibernate环境配置。");
logger.debug("开始获取Hibernate初始化参数");
try{
Configuration config = new Configuration().configure();
SessionFactory sf = config.buildSessionFactory();
logger.debug("构建SessionFactory对象成功！");
session = sf.openSession();
}catch(HibernateException he){
logger.error("发生持久异常，请通知数据库管理员");
he.printStackTrace();
throw new PersistException("初始化Hibernate环境时发生错误！");
}
logger.debug("构建Session对象成功！");
logger.info("设置Hibernate环境成功！");
}
public boolean addUser(TBUser user){
Transaction trans = null;
logger.info("开始添加新用户!");
try{
logger.debug("开始用户添加事务");
trans = session.beginTransaction();
// session.refresh(user,LockMode.UPGRADE);
session.save(user);
session.flush(); //刷新cache
trans.commit(); //提交到数据库
logger.debug("用户添加成功！");
return true;
}catch(HibernateException he){
try{
logger.error("添加用户时发生异常！异常为："+he.getMessage());
trans.rollback();
logger.info("数据库操作已撤消!");
}catch(HibernateException he2){
he2.printStackTrace();
logger.fatal("发生致命错误，请通知系统管理员！");
}
}
return false;
}
public UserBean getUser(UserBean user){
String qname = user.getUname();
String qpass = user.getPasswd();
String hql = " from TBUser where uname='"+qname+"'"+" and "+" passwd='"+qpass+"'";
List userList = null;
try{
userList = session.find(hql);
}catch(HibernateException he){
logger.error("发生持久错误，为："+he.getLocalizedMessage());
return null;
}
if(userList.size()!=0){
TBUser tuser = (TBUser) userList.get(0);
UserBean ruser = new UserBean();
ruser.setUname(tuser.getUname());
ruser.setPasswd(tuser.getPasswd());
ruser.setSummary(tuser.getSummary());
ruser.setEmail(tuser.getEmail());
ruser.setUid(ruser.getUid());
return ruser;
}else{
return null;
}
}
}
第九步:根据持久层编写代理业务Bean
package edu.swk.struts.ebusiness.user;
import edu.swk.struts.ebusiness.persist.UserPersist;
import edu.swk.struts.ebusiness.persist.PersistException;
import org.apache.log4j.Logger;
public class UserLogic {
private static UserPersist up;
static Logger logger = Logger.getLogger(UserLogic.class);
static{
try{
logger.info("初始化数据库环境!");
up = new UserPersist();
}catch(PersistException he){
logger.error("初始化数据库环境失败！，错误信息为："+he.getMessage());
}
}
public boolean login(UserBean user){
logger.info("开始进行用户登陆逻辑处理!");
UserBean correntUser = up.getUser(user);
if(correntUser==null){
logger.debug("用户不存在，登陆失败！");
return false;
}else{
logger.debug("用户存在，登陆成功！");
return true;
}
}
public boolean register(UserBean user){
return false;
}
}
第十步:在Action中调用代理业务Bean与在表单页面中得到的数据进行操作.
package edu.swk.struts.ebusiness.user;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionForm;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.Action;
import org.apache.log4j.Logger;
public class LoginAction extends Action {
static Logger logger = Logger.getLogger(LoginAction.class);
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request,
HttpServletResponse response) {
logger.info("开始进行用户登陆操作");
UserForm userForm = (UserForm) form;
UserBean ub = new UserBean();
ub.setUname(userForm.getUname());
ub.setPasswd(userForm.getPasswd());
logger.debug("用户登陆信息为：");
logger.debug("用户名："+ub.getUname());
logger.debug("用户密码："+ub.getPasswd());
UserLogic ul = new UserLogic();
boolean done = ul.login(ub);
if(done){
logger.info("登陆成功，转入登陆页面");
return mapping.findForward("loginSuccess");
}else{
logger.info("登陆失败！");
return mapping.findForward("loginFailure");
}
}
}
第十二步:配置struts-config.xml文件,(配置Action和Action Form Bean之间的关系)
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">
<struts-config>
<form-beans>
<form-bean name="userForm" type="edu.swk.struts.ebusiness.user.UserForm" />
</form-beans>
<action-mappings>
<action input="/register.jsp" name="userForm" path="/register" scope="request" type="edu.swk.struts.ebusiness.user.RegisterAction" validate="true">
<forward name="registerSuccess" path="/user/login.jsp" />
<forward name="registerFailure" path="/user/reg_fail.jsp" />
</action>
<action input="login.jsp" name="userForm" path="/login" scope="request" type="edu.swk.struts.ebusiness.user.LoginAction">
<forward name="loginSuccess" path="/index.jsp" />
<forward name="loginFailure" path="/user/login_fail.jsp" />
</action>
</action-mappings>
<message-resources parameter="ApplicationResources" />
</struts-config>
第十三步:配置web.xml文件(一般无需进行改动)
<?xml version="1.0" encoding="UTF-8"?>

return false;
}else{
logger.debug("用户存在，登陆成功！");
return true;
}
}
public boolean register(UserBean user){
return false;
}
}
第十步:在Action中调用代理业务Bean与在表单页面中得到的数据进行操作.

logger.info("登陆成功，转入登陆页面");
return mapping.findForward("loginSuccess");
}else{
logger.info("登陆失败！");
return mapping.findForward("loginFailure");
}
}
}
第十二步:配置struts-config.xml文件,(配置Action和Action Form Bean之间的关系)
<?xml version="1.0" encoding="UTF-8"?>

<form-bean name="userForm" type="edu.swk.struts.ebusiness.user.UserForm" />
</form-beans>
<action-mappings>
<action input="/register.jsp" name="userForm" path="/register" scope="request" type="edu.swk.struts.ebusiness.user.RegisterAction" validate="true">
<forward name="registerSuccess" path="/user/login.jsp" />
<forward name="registerFailure" path="/user/reg_fail.jsp" />
</action>
<action input="login.jsp" name="userForm" path="/login" scope="request" type="edu.swk.struts.ebusiness.user.LoginAction">
<forward name="loginSuccess" path="/index.jsp" />
<forward name="loginFailure" path="/user/login_fail.jsp" />
</action>
</action-mappings>
<message-resources parameter="ApplicationResources" />
</struts-config>
第十三步:配置web.xml文件(一般无需进行改动)
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<!-- 过滤器,解决数据与页面交互时中英文件转换问题 -->

</filter>
<filter-mapping>
<filter-name>setencodingfilter</filter-name>
<url-pattern>/*</url-pattern>
