1.匯入struts和spring各自需要的jar包， 再匯入兩者整合需要的jar包

2.UserDao.java

package com.ssh.dao;

import org.springframework.stereotype.Repository;

@Repository 
public class UserDao {

    public void add() {
        System.out.println("userDao ......");
    }

}

UserServiece.java

package com.ssh.service;

import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import com.ssh.dao.UserDao;

//@Service(value="userService")--value="userService"可不要，因為UserServiece的預設bean的name為小寫字母開頭的類名
@Service
public class UserService {
	
    @Resource
    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 org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;

import com.opensymphony.xwork2.ActionSupport;
import com.ssh.service.UserService;

@Controller
@Scope("prototype")
public class UserAction extends ActionSupport {
	
    @Autowired
    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 .......");
        // 呼叫userService中方法發
        userService.add();

        return NONE;    // 表示返回到任何頁面中去
    }

}
 

2.三個配置檔案

struts對應的struts.xml檔案

<?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>
	<!-- 在struts.xml中指定objectFactory物件工廠為spring，即action的建立交由spring進行 -->
	<constant name="struts.objectFactory" value="spring"/>
	
	<package name="demo1" extends="struts-default" namespace="/">
        <!-- class屬性是從Spring IoC中獲取的 -->
        <action name="userAction" class="userAction">
        </action>

    </package>
</struts>
 

spring對應的applicationContext.xml檔案

<?xml version="1.0" encoding="UTF-8"?>

<!-- 引入的Spring的約束，已經很全了 -->
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	<!-- 開啟註解掃描 -->
    <context:component-scan base-package="com.ssh">  
        <!-- 不掃描controller包下的UserController類，既去除註解   -->
        <!-- <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> -->  
    </context:component-scan>
    <!-- userDao -->
    <!-- <bean id="userDao" class="com.ssh.dao.UserDao"></bean> -->

    <!-- userService -->
    <!-- <bean id="userService" class="com.ssh.service.UserService">
        <property name="userDao" ref="userDao"></property>
    </bean> -->
    
    <!-- 配置action的物件 -->
    <!-- 注意action是多例項的，因此我們這裡把scope配置為prototype的 -->
    <!-- <bean id="userAction" class="com.ssh.action.UserAction" scope="prototype">
        <property name="userService" ref="userService"></property>
    </bean> -->
     

</beans>

<web-app>
	<!-- 1.配置struts2的過濾器 -->
    <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>
 	
 	<!-- spring配置檔案對應的引數，如果applicationContext.xml放在/WEB-INF/目錄下，可以忽略；若不是，則需要配置 -->
 	<!-- <context-param>
	 <param-name>contextConfigLocation</param-name>
	 <param-value>/WEB-INF/applicationContext-*.xml,classpath*:applicationContext-*.xml</param-value>
	</context-param> -->
	<!-- 2.配置Spring的監聽器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
     
</web-app>
