代码 code:

 <action name="addRoleMenu" class="xxx.action.system.RoleAction" method="addRoleMenu">
    	 <param name="operation">-1</param>
    	 <result name="init" type="chain">
            <param name="namespace">/system</param>
    		<param name="actionName">queryMenuList</param>
    	 </result>
    </action>


 <action name="queryMenuList" class="xxx.action.system.MenuAction" method="queryMenuList">
   	 	<result name="success">/system/menu_list.jsp</result>
   	 	<result name="operation">/system/role_menu_add.jsp</result>
    </action>

这个问题没有人遇到过?没有 大侠,高手吗?太失望了?

RoleAction不能强转为MenuAction类，很明显的错误

<result name="init" type="chain"> 
           <param name="namespace">/system</param> 
        <param name="actionName">queryMenuList</param> 
     </result> 
这个 /system/queryMenuList.do  不是 RoleAction 中方法,是MenuAction中的方法,下面有配置 什么时候需要强行转换了?  而且我用 chain 怎么涉及到强制转换了.
我怀疑,是spring AOP　代理Action 后,如果用chain 只能在同一个Action中chian不能夸 Action

我觉得可以从设计上优化一下，避免action跳action，在service层引入，或者作为当前类中的函数，避免这些费时的事情
