2、右击项目添加spring开发能力

3、导入struts2的spring支持包struts2-spring-plus-2.0.11.jar(注意应该与struts核心包版本一致)，建立path

4、修改web.xml,添加监听器，param-value中定义applicationContext配置路径

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xmlns="http://java.sun.com/xml/ns/javaee"
      xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
       xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
        http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
    
      <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>
      
      
    	<context-param>
    	<param-name>contextConfigLocation</param-name>
    	<param-value>/WEB-INF/classes/applicationContext.xml</param-value>
    	</context-param>
    	
    	<listener>
    	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    	</listener>
      
    </web-app>

5、在applicationContext.xml中配置mainAction的Bean

<?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:p="http://www.springframework.org/schema/p"
    	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd">
    
    	<bean id="mainAction" class="action.MainAction"></bean>
    </beans>

6、修改在struts.xml中mainAction的class属性值为Bean的id值

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE struts PUBLIC
            "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
            "http://struts.apache.org/dtds/struts-2.0.dtd">
    	<struts>
    		<package name="default" extends="struts-default">
    			
    			<action name="main" class="mainAction">
    				<result name="success">/success.jsp</result>
    				<result name="error">/error.jsp</result>
    			</action>
    		</package>
    		
    	</struts>

7、启动Tomcat测试结果
