在这个项目中，用户在登录页面输入登录名和密码，则跳转到另外一个欢迎页面，反之，将进入失败页面。

2. 实验内容1.1. 目标用户在登录页面输入登录名和密码，则跳转到另外一个欢迎页面，反之，将进入失败页面。

1.2. 需求分析登录界面几乎是所有网站都会用到的功能，因此登陆界面制作的技术是需要不断的学习，不断的提高的。

登录需要往数据库中查询，因此数据库的应用不可忽视。

1.3. 采用技术j2ee,struts2,hibernate,spring.1.4. 模块设计1．完成ssh91)创建数据库2)创建Web Project，名为ssh93)添加Struts 2框架4)创建login.jsp5)创建LoginAction.java6)创建login_success.jsp7)创建login_error.jsp8)部署，测试struts22．集成Spring9)添加Spring框架10)添加Struts spring支持包spring-struts-plugin-2.0.11.jar11)修改web.xml内容112)创建struts.properties13)修改struts.xml14)修改applicationContext.xml15)部署测试3．加载Hibernate框架16)添加Spring框架17)修改LoginAction.java18)修改applicationContext.xml19)部署测试1.5. 编码实现数据库内容如下：建表语句：CREATE TABLE user(id int(10) not null auto_increment,username varchar(10) not null,password varchar(10) not null,primary key (id))ENGINE=InnoDB DEFAULT CHARSET=GBK; 其中已有数据：LoginAction.java代码如下：package org;import java.util.List;import org.hibernate.SessionFactory;import org.hibernate.Query;import org.hibernate.classic.Session;import com.opensymphony.xwork2.ActionSupport; public class LoginAction extends ActionSupport{ private String username;private String password;private SessionFactory sessionFactory;public String getUsername(){return username;}public void setUsername(String username){ername=username;}public String getPassword(){return password;}public void setPassword(String password){this.password=password;}public SessionFactory getSessionFactory(){return sessionFactory;}public void setSessionFactory(SessionFactory sessionFactory){this.sessionFactory=sessionFactory;}public String execute() throws Exception{Session session=sessionFactory.openSession();String hql="from User u where ername=? and u.password=?";Query query=session.createQuery(hql);query.setParameter(0,username);query.setParameter(1,password);List user=query.list();session.close();if(user.size()>0){return SUCCESS;}else{return ERROR;}}}User.hbm.xml代码如下：<?xml version="1.0" encoding="utf-8"?><!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "/hibernate-mapping-3.0.dtd"><!--Mapping file autogenerated by MyEclipse Persistence Tools--><hibernate-mapping><class name="er" table="user" catalog="test"><id name="id" type="ng.Integer"><column name="id" /><generator class="native" /></id><property name="username" type="ng.String"><column name="username" length="10" not-null="true" /></property><property name="password" type="ng.String"><column name="password" length="10" not-null="true" /></property></class></hibernate-mapping>User.hbm.xml代码如下：package org;import org.hibernate.HibernateException;import org.hibernate.Session;import org.hibernate.cfg.Configuration;public class HibernateSessionFactory {private static String CONFIG_FILE_LOCA TION = "/hibernate.cfg.xml";private static final ThreadLocal<Session> threadLocal = new ThreadLocal<Session>();private static Configuration configuration = new Configuration();private static org.hibernate.SessionFactory sessionFactory;private static String configFile = CONFIG_FILE_LOCATION;static {try {configuration.configure(configFile);sessionFactory = configuration.buildSessionFactory();} catch (Exception e) {System.err.println("%%%% Error Creating SessionFactory %%%%");e.printStackTrace();}}private HibernateSessionFactory() {}public static Session getSession() throws HibernateException {Session session = (Session) threadLocal.get();if (session == null || !session.isOpen()) {if (sessionFactory == null) {rebuildSessionFactory();}session = (sessionFactory != null) ? sessionFactory.openSession(): null;threadLocal.set(session);}return session;}public static void rebuildSessionFactory() {try {configuration.configure(configFile);sessionFactory = configuration.buildSessionFactory();} catch (Exception e) {System.err.println("%%%% Error Creating SessionFactory %%%%");e.printStackTrace();}}public static void closeSession() throws HibernateException {Session session = (Session) threadLocal.get();threadLocal.set(null);if (session != null) {session.close();}}public static org.hibernate.SessionFactory getSessionFactory() {return sessionFactory;}public static void setConfigFile(String configFile) {HibernateSessionFactory.configFile = configFile;sessionFactory = null;}public static Configuration getConfiguration() {return configuration;}}LoginAction.java代码如下：package org;public class User implements java.io.Serializable { private Integer id;private String username;private String password;public User() {}public User(String username, String password) {ername = username;this.password = password;}public Integer getId() {return this.id;}public void setId(Integer id) {this.id = id;}public String getUsername() {return ername;}public void setUsername(String username) {ername = username;}public String getPassword() {return this.password;}public void setPassword(String password) {this.password = password;}}配置struts.xml文件，代码如下：<!DOCTYPE struts PUBLIC"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN""/dtds/struts-2.0.dtd"><struts><include file="struts-default.xml"/><package name="default" extends="struts-default"><action name="login" class="org.LoginAction"><result name="error">/login_error.jsp</result><result name="success">/login_success.jsp</result></action></package></struts>创建login.jsp，代码如下：<%@ page contentType="text/html;charset=gb2312" %><%@ taglib prefix="s" uri="/struts-tags" %><html><head><title>登录页面</title></head><body><form action="login.action" method="post">用户登录<br>用户名:<input type="text" name="username"/><br>密码:<input type="password" name="password"/><br><input type="submit" value="登录"/><br></form></body></html>创建login_success.jsp，代码如下：<%@ page contentType="text/html;charset=gb2312" %><%@ taglib prefix="s" uri="/struts-tags" %><html><body><h2>您好！用户<s:property value="username"/>欢迎您登录成功</h2> </body></html>创建login_error.jsp，代码如下：<%@ page contentType="text/html;charset=gb2312" %><%@ taglib prefix="s" uri="/struts-tags" %><html><body><h2>登录失败</h2></body></html>修改web.xml内容，使得程序增加对Spring的支持<?xml version="1.0" encoding="UTF-8"?><web-app version="2.5"xmlns="/xml/ns/javaee"xmlns:xsi="/2001/XMLSchema-instance"xsi:schemaLocation="/xml/ns/javaee/xml/ns/javaee/web-app_2_5.xsd"><filter><filter-name>struts2</filter-name><filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class> </filter><filter-mapping><filter-name>struts2</filter-name><url-pattern>/*</url-pattern></filter-mapping><listener><listener-class>org.springframework.web.context.ContextLoaderListener </listener-class></listener><context-param><param-name>contextConfigLocation</param-name><param-value>/WEB-INF/classes/applicationContext.xml</param-value></context-param><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list></web-app>使得struts 2的类(struts.properties)的生成交给Spring完成。
