一、创建SSH2项目，导入Struts2并测试。

 

 

web.xml

     
       
            
          
       
        index.jsp
         
        
            
       
        struts2
             
       
                  org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter      
         
        
            
       
        struts2
             
       
        *.action
         
      
     

default.jsp

<%@ page language="java" contentType="text/html; charset=utf-8"    pageEncoding="utf-8"%><%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
     default page

UserAction.java

package com.cwq.action;import com.opensymphony.xwork2.ActionSupport;public class UserAction extends ActionSupport {    @Override    public String execute() throws Exception {        // TODO Auto-generated method stub        //return super.execute();        return SUCCESS;    }    /**     * @param args     */    public static void main(String[] args) {        // TODO Auto-generated method stub    }}

struts.xml

     
         
              
                   
        
         default.jsp
                
           
      
     

发布项目，启动Tomcat，运行结果：

 二、导入Spring包，配置数据源

三，Spring与Hibernate整合

在web.xml中加入

<!-- 必须放在顶上 -->

 <!-- 指定spring的配置文件，默认从web根目录寻找配置文件，我们可以通过spring提供的classpath:前缀指定从类路径下寻找 -->

 <context-param>

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

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

 </context-param>

 <!-- 对Spring容器进行实例化 -->

 <listener>

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

 </listener>

     
             
          
          
             
       
        contextConfigLocation
              
       
        classpath:applicationContext.xml
           
          
          
                
       
        org.springframework.web.context.ContextLoaderListener
           
            
            
          
       
        index.jsp
         
        
            
       
        struts2
             
       
                  org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter      
         
        
            
       
        struts2
             
       
        *.action
         
      
     

applicationContext.xml(自动生成)

     
         
              
               
               
               
               
           
          
              
                   
                
               
                   
                        
         
                              org.hibernate.dialect.MySQLDialect                
                     
                
           
      
     

测试，发布，启动Tomcat，如果启动成功则整合成功。

 四、根据数据库反向生成代码

  

 

Users.java

package com.cwq.model;import java.sql.Timestamp;/** * Users entity. @author MyEclipse Persistence Tools */public class Users implements java.io.Serializable {    // Fields    private Integer id;    private String username;    private String password;    private Timestamp birthdate;    // Constructors    /** default constructor */    public Users() {}    /** full constructor */    public Users(String username, String password, Timestamp birthdate) {        this.username = username;        this.password = password;        this.birthdate = birthdate;    }    // Property accessors    public Integer getId() {        return this.id;    }    public void setId(Integer id) {        this.id = id;    }    public String getUsername() {        return this.username;    }    public void setUsername(String username) {        this.username = username;    }    public String getPassword() {        return this.password;    }    public void setPassword(String password) {        this.password = password;    }    public Timestamp getBirthdate() {        return this.birthdate;    }    public void setBirthdate(Timestamp birthdate) {        this.birthdate = birthdate;    }}

user.hbm.xml

UserDao.java

package com.cwq.dao;import java.sql.Timestamp;import java.util.List;import org.hibernate.LockMode;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.context.ApplicationContext;import org.springframework.orm.hibernate3.support.HibernateDaoSupport;import com.cwq.model.Users;/** * A data access object (DAO) providing persistence and search support for Users * entities.

applicationContext.xml

     
         
              
               
               
               
               
           
          
              
                   
                
               
                   
                        
         
                              org.hibernate.dialect.MySQLDialect                
                     
                
               
                   
                        
         
          com/cwq/model/Users.hbm.xml
         
                
       
          
              
                   
                
           
      
     

 五、Struts整合Spring

UserAction.java

package com.cwq.action;import java.util.List;import com.cwq.dao.UsersDAO;import com.cwq.model.Users;import com.opensymphony.xwork2.ActionSupport;public class UserAction extends ActionSupport {        private List
     
       users = null;        private UsersDAO userDao;        public void setUserDao(UsersDAO userDao) {        this.userDao = userDao;    }    @Override    public String execute() throws Exception {        // TODO Auto-generated method stub        //return super.execute();        users = userDao.findAll();        return SUCCESS;    }    public List
      
        getUsers() {        return users;    }    public void setUsers(List
       
         users) {        this.users = users;    }    /**     * @param args     */    public static void main(String[] args) {        // TODO Auto-generated method stub    }}
       
      
     

applicationContext.xml

加入

<bean id="userAction" class="com.cwq.action.UserAction">

  <property name="userDao"><!-- 依赖注入（单例），在UserAction中必须要有一个userDao的属性有其set方法 -->

   <ref bean="UsersDAO"/>

  </property>

 </bean>

     
         
              
               
               
               
               
           
          
              
                   
                
               
                   
                        
         
                              org.hibernate.dialect.MySQLDialect                
                     
                
               
                   
                        
         
          com/cwq/model/Users.hbm.xml
         
                
       
          
              
                   
                
           
          
              
       
                    
                
           
          
     

 struts.xml

加入

<!-- 由Spring来代理控制层 -->

 <constant name="struts.objectFactory" value="spring" />

     
         
          
              
              
               
       
                    
        
         default.jsp
                
           
      
     

default.jsp

<%@ page language="java" contentType="text/html; charset=utf-8"    pageEncoding="utf-8"%><%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
     default page
      
      
           ${user.username}--${user.password}--${user.birthdate} 
       
      

 如果要指定进入某个action加入下面代码

 <script type="text/javascript">

  document.location.href = "showUsers.action";

 </script>

index.jsp

<%@ page language="java" import="java.util.*" pageEncoding="GB18030"%><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%>                  
         
         
             
         
         
                   This is my JSP page.
