坑爹呀...保存的一篇掉了，只得重写....

话说前两篇介绍了怎么配置Struts和Hibernate，这篇就用一个简单的例子：用户注册，将这两种技术整合起来。

1. 写一个注册界面registration.jsp，这里用到了Java国际化的一些标记，能看懂的就看，看不懂的先别理他....

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><%@ taglib uri="/struts-tags" prefix="s" %>    <%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><base href="<%=basePath%>"><title>Insert title here</title><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><meta http-equiv="pragma" content="no-cache"><meta http-equiv="cache-control" content="no-cache"><meta http-equiv="expires" content="0">    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"><meta http-equiv="description" content="This is my page"></head><body><p>Registration Test</p><s:form name="registrationFrm" action="registration"><s:textfield name="name" key="username"></s:textfield><s:password  name="password" key="password"></s:password><s:textfield name="birthday" key="birthday"/><s:submit label="submit"></s:submit></s:form><s:actionerror/></body></html>

2. 在struts.xml中增加一个action的mapping

<action name="registration" class="test.RegistrationAction"><result name="success" >index.jsp</result><result name="input">registration.jsp</result><result name="error">registration.jsp</result></action>

3. 增加一个注册的action类

package test;import com.opensymphony.xwork2.ActionSupport;import com.opensymphony.xwork2.ModelDriven;import com.test.model.User;import com.test.service.UserService;public class RegistrationAction extends ActionSupport implements ModelDriven<User> {private User user = new User();public User getModel() {return user;}public String execute(){System.out.println(user.toString());UserService us = new UserService();us.saveUser(user);return SUCCESS;}}

上面的类还引用了一个业务逻辑类，如下：

package com.test.service;import com.test.dao.UserDao;import com.test.model.User;public class UserService {private UserDao userdao = new UserDao();public void saveUser(User user){userdao.saveUser(user);}public User getUserInfo(String username){User user = userdao.getUserbyName(username);return user;}public boolean login(String username, String password){User user = userdao.getUserbyLoginInfo(username, password);if (null != user){return true;}else{return false;}}}

跟数据库的打交道的DAO类：

package com.test.dao;import org.hibernate.Query;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.hibernate.Transaction;import org.hibernate.cfg.Configuration;import com.test.model.User;public class UserDao {private SessionFactory factory;public UserDao(){Configuration cfg = new Configuration().configure();this.factory = cfg.buildSessionFactory();}public void saveUser (User user){Session session = this.openSession();Transaction tx = null;try{//打开事务tx = session.beginTransaction();session.save(user);//关闭事务tx.commit();}catch(Exception ex){tx.rollback();ex.printStackTrace();}finally{session.close();}}public User getUserbyName(String username){Session session = this.openSession();String hql = "from user where name=:name";Query query = session.createQuery(hql);query.setString("name", username);//用uniqueResult获取唯一对象，或者用list获取对象列表User user = (User) query.uniqueResult();return user;}public User getUserbyLoginInfo(String username, String password){Session session = this.openSession();String hql = "from User where name=:name and password=:password";Query query = session.createQuery(hql);query.setString("name", username);query.setString("password", password);//用uniqueResult获取唯一对象，或者用list获取对象列表User user = (User) query.uniqueResult();return user;}public Session openSession(){Session session = this.factory.openSession();return session;}}

4. 注册成功后的显示jsp文件:
index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%><%@ taglib uri="/struts-tags" prefix="s" %>    <%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><base href="<%=basePath%>"><title>SSH2 - Index</title><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><meta http-equiv="pragma" content="no-cache"><meta http-equiv="cache-control" content="no-cache"><meta http-equiv="expires" content="0">    <meta http-equiv="keywords" content="easyTalk"><meta http-equiv="description" content="This is my page"></head><body><p> <s:text name="username" /> <s:property value="#request.name"/></p><p> <s:text name="password" /> <s:property value="#request.password" /><p> <s:text name="birthday" /> <s:property value="#request.brithday"/></body></html>

5. 开始验证功能：
