Struts2.1 处理未知Action 和访问不存在的页面

你可以配置个默认action，当请求的action不存在时，他就会去找默认的action

  
          
            /default.jsp  
          

Struts.xml配个全局的 如

 
  /exception.jsp 
   

Action Default  

Usually, if an action is requested, and the framework can't map the request to an action name, the result will be the usual "404 - Page not found" error. But, if you would prefer that an omnibus action handle any unmatched requests, you can specify a default action. If no other action matches, the default action is used instead.
