源码：

<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN"

<struts>
<package name="struts" extends="struts-default">
<!-- 前面是action类名(com.hw.controller.UserAction) ，后面是方法名
,如果和spring整合class里也可以用控制层注解 -->
<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中默认为转发即 type="dispatcher",redirect为重定向-->
<result name="success" type="redirect">user_list</result>
<result name="list">/WEB-INF/user/list.jsp</result>
</action>
</package>
</struts>
