直接码项目

1.项目目录

![70][]

先导入struts和spring各自需要的jar包，再导入两者整合需要的jar包

2.UserDao.java

package com.ssh.dao;
    
    public class UserDao {
    
        public void add() {
            System.out.println("userDao ......");
        }
    
    }

UserService.java

package com.ssh.service;
    
    import com.ssh.dao.UserDao;
    
    public class UserService {
    
        private UserDao userDao;
    
        public UserDao getUserDao() {
            return userDao;
        }
    
        public void setUserDao(UserDao userDao) {
            this.userDao = userDao;
        }
    
        public void add() {
            System.out.println("userService ......");
            userDao.add();
        }
    
    }

UserAction.java

package com.ssh.action;
    
    import com.opensymphony.xwork2.ActionSupport;
    import com.ssh.service.UserService;
    
    public class UserAction extends ActionSupport {
    
        private UserService userService;
    
        public UserService getUserService() {
            return userService;
        }
    
        public void setUserService(UserService userService) {
            this.userService = userService;
        }
    
        @Override
        public String execute() throws Exception {
    
            System.out.println("userAction .......");
            // 调用userService中方法发
            userService.add();
    
            return NONE;    // 表示返回到任何页面中去
        }
    
    }

3.三个配置文件

struts.xml

<?xml version="1.0" encoding="UTF-8"?>
    
    <!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
        "http://struts.apache.org/dtds/struts-2.3.dtd">
    
    <struts>
    	
    	<constant name="struts.objectFactory" value="spring"/>
    	
    	<package name="demo1" extends="struts-default" namespace="/">
            
            <action name="userAction" class="userAction">
            </action>
    
        </package>
    </struts>

applicationContext.xml(默认放在WEB-INF目录下，如果放在其他位置需要在web.xml文件中指定）

<?xml version="1.0" encoding="UTF-8"?>
    
    
    <beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:context="http://www.springframework.org/schema/context"
        xmlns:aop="http://www.springframework.org/schema/aop"
        xmlns:tx="http://www.springframework.org/schema/tx"
        xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx.xsd">
    
        
        
        <bean id="userDao" class="com.ssh.dao.UserDao"></bean>
    
        
        <bean id="userService" class="com.ssh.service.UserService">
            <property name="userDao" ref="userDao"></property>
        </bean>
        
        
        
        <bean id="userAction" class="com.ssh.action.UserAction" scope="prototype">
            <property name="userService" ref="userService"></property>
        </bean>
    
    </beans>

在web.xml中配置struts2的过滤器

<web-app>
    	
        <filter>
            <filter-name>struts2</filter-name>
            <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
        </filter>
     
        <filter-mapping>
            <filter-name>struts2</filter-name>
            <dispatcher>FORWARD</dispatcher>
            <dispatcher>REQUEST</dispatcher>        
            <url-pattern>/*</url-pattern>
        </filter-mapping>
     	
     	
     	
    	
        <listener>
            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
        </listener>
         
    </web-app>

4.index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
        pageEncoding="UTF-8"%>
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>Insert title here</title>
    </head>
    <body>
    	<a href="userAction">点击后会，发送action为userAction的请求，由拦截器拦截，跳转到空的页面</a>
    </body>
    </html>

5.测试

运行index.jsp，点击超链接，跳转到空白页

控制台打印如下结果

6.整合Struts和Spring的基本思路是将Action生命周期由原本的Struts进行管理，交由Spring进行管理
