实验八 SSH整合

1、实验八 SSH整合实验内容：整合Struts2.1+Spring3.0+Hibernate3.2实验目的：1. 掌握Spring的基本配置2. 掌握控制反转的配置3. 掌握SSH整合的基本步骤1. 在MyEclipse8.0新建一个web project项目2. 在name中输入项目名称（如SSH）并选择Java EE5.0然后点击finish3. 如图选择yes4. 添加spring的jar包5. 选择Spring3.0的五个jar包分别是Spring 3.0 AOP Libraries、Spring 3.0 Core Libraries、Spring 3.0 Persistence Cor

2、e Libraries、Spring 3.0 Persistence JDBC Libraries、Spring 2.5 Web Libraries，并选择Copy checked Library，然后点击next6. 最后点击finish7. 创建数据源，将窗口切换到MyEclipse Database Explorer8. New一个数据源9. 选择相应的template，填写相应的URL，jar包以及class name如图10. 然后点击Test Driver,测试成功后点击next11. 选择映射数据库，add添加相应的数据库12. .然后点击偶ok，再点击finish13. 现在开

3、始添加Hibernate3.2，将视图转换到Java视图，然后添加hibernate的jar包14. 在其中修改如图，然后next15. 选择spring的配置文件，然后点击next16. 选择已经存在的spring配置文件，然后点击next17. 然后点击next18. 在DB Driver中选择新建的哪个=那个数据源（例如ssh）19. 去掉对钩，然后点击finish20. 然后添加Struts2.021. 选择struts2.1版本，点击next22. .选择相应的jar包，然后点击finish23. 在项目中有三个包冲突，需要我们手动去掉，分别是asm.jar、asm-attrs.ja

4、r、cglib-2.1.3.jar （1）选择项目右键单击选择属性（2） 然后选择Java Build Path,再选择Librarise （3） 选中所要删除的jar，然后点击Remove，最后点击ok就可以了，添加SSH包就完成了。 下面是一个登录的例子1. 首先应该编写PO类，以及它的映射文件xxx.xml（1） 建议使用hibernate的逆向工程，可以直接实现（推荐使用，多表的时候更容易）1 将窗口切换到MyEclipse Database Explorer，打开我们所创建的数据源，一直到table2 选择需要的表，右键单击选择hibernate逆向工程3 选择工程中放置的包4 如图

5、依次选择然后点击finish（2）直接手写1 也可以直接编写如下User.javapackage cn.ccutsoft.bean.po;import java.io.UnsupportedEncodingException;public class User private int id;private String username;private String password;public int getId() return id;private void setId(int id) this.id = id;public String getUsername() return us

6、ername;public void setUsername(String username) this.username = username;public String getPassword() return password;public void setPassword(String password) this.password = password;User.hbm.xml<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE hibernate-mapping PUBLIC &qu

7、ot;-/Hibernate/Hibernate Mapping DTD 3.0/EN" "<hibernate-mapping package="cn.ccutsoft.bean.po"> <class name="User" table="t_user"> <id name="id" column="id"> <generator class="native"/> </id> <prop

8、erty name="username" column="username"/> <property name="password" column="password"/> </class></hibernate-mapping>2 然后在applicationContext.xml中添加 <property name="mappingResources"> <list> <value>cn/ccutsoft/bean

9、/po/User.hbm.xml</value> </list> </property>3. 然后编写接口IUser.java package cn.ccutsoft.bean.dao; import cn.ccutsoft.bean.po.User; public interface IUser public User findByName(String username); 4. 编写IUser接口的实现类，UserDaO.javapackage cn.ccutsoft.bean.dao;import java.util.List;import org.

10、springframework.orm.hibernate3.support.HibernateDaoSupport;import cn.ccutsoft.bean.po.User;public class UserDAO extends HibernateDaoSupport implements IUser SuppressWarnings("unchecked")public User findByNameAndPassword(String username) List<User> list = this.getHibernateTemplate().f

11、ind("from User as u where u.username = ? ", username); if(list.size() > 0)return list.get(0);elsereturn null;5. 在applicationContext.xml中添加6. <bean id="userDAO" class="cn.ccutsoft.bean.dao.UserDAO">7. <property name="sessionFactory" ref="sessio

12、nFactory"/>8. </bean>编写接口ILoginCheck.javapackage cn.ccutsoft.bean.service;import cn.ccutsoft.bean.po.User;public interface ILoginCheck public boolean isLogin(User user);9. 编写接口ILoginCheck.java的实现类LoginCheck.javapackage cn.ccutsoft.bean.service;import cn.ccutsoft.bean.dao.IUser;import c

13、n.ccutsoft.bean.dao.UserDAO;import cn.ccutsoft.bean.po.User;public class LoginCheck implements ILoginCheck private IUser userDAO;public void setUserDAO(IUser userDAO) this.userDAO = userDAO;public boolean isLogin(User user) User newUser = userDAO.findByName(user.getUsername();if(newUser = null)retur

14、n false;else if(!newUser.getPassword().equals(user.getPassword()return false;elsereturn true;10. 然后在applicationContext.xml中添加<bean id="loginCheck" class="cn.ccutsoft.bean.service.LoginCheck"> <property name="userDAO" ref="userDAO"/></bean>11.

15、 编写LoginAction.javapackage cn.ccutsoft.action;import java.util.Map;import cn.ccutsoft.bean.po.User;import cn.ccutsoft.bean.service.ILoginCheck;import cn.ccutsoft.bean.service.LoginCheck;import com.opensymphony.xwork2.ActionContext;import com.opensymphony.xwork2.ActionSupport;public class LoginAction

16、 extends ActionSupport private User user;private ILoginCheck loginCheck;public void setLoginCheck(ILoginCheck loginCheck) this.loginCheck = loginCheck;public User getUser() return user;public void setUser(User user) this.user = user;public String execute()boolean flag = loginCheck.isLogin(user);if(f

17、lag)ActionContext act = ActionContext.getContext();Map<String,String> map = act.getSession();map.put("username", user.getUsername();return SUCCESS;elsereturn ERROR;12. 在applicationContext.xml中添加<bean id="loginAction" class="cn.ccutsoft.action.LoginAction"> &

18、lt;property name="loginCheck" ref="loginCheck"></property></bean>13. 在struts.xml中添加 <package name="ssh" extends="struts-default"> <action name="loginAction" class="loginAction"> <result name="success"

19、>/success.jsp</result> <result name="error">/fail.jsp</result> </action></package>14. 在web.xml中添加如下代码 <listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener><context-param> &

20、lt;param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/classes/applicationContext.xml </param-value> </context-param> 15. 然后添加页面Index.jsp<% page language="java" import="java.util.*" pageEncoding="utf-8"%><%taglib uri=&

21、quot;/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&qu
