- 配置web.xml

（2）
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
- 配置 spring文件

<welcome-file>index.jsp</welcome-file>

</web-app>
- 配置struts文件

源碼：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN"
"http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
<package name="struts" extends="struts-default">
<!-- 前面是action類名(com.hw.controller.UserAction) ，后面是方法名
,如果和spring整合class里也可以用控制層注解 -->
<action name="user_*" class="userController" method="{1}">
<result name="add">/WEB-INF/user/add.jsp</result>
<result name="update">/WEB-INF/user/update.jsp</result>
<!-- struts中默認為轉發即 type="dispatcher",redirect為重定向-->
<result name="success" type="redirect">user_list</result>
<result name="list">/WEB-INF/user/list.jsp</result>
</action>
</package>
</struts>
