1、先完成Struts2简单登录例子的实现，当前的目录结构如下

2、右击项目添加spring开发能力

70 1

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>
  <!--      spring配置文件位置  -->
    <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/classes/applicationContext.xml</param-value>
    </context-param>
    <!--     spring监听器  -->
    <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">
            <!-- 用户登录action -->
            <action name="main" class="mainAction">
                <result name="success">/success.jsp</result>
                <result name="error">/error.jsp</result>
            </action>
        </package>
        <!-- <constant name="struts.i18n.encoding" value="gb2312"></constant> -->
    </struts>
