解决方案 »

  1.   


    红色部分的总拦截器能在struts2-core-2.1.8.1包下找到吗？是不是写错了
      

  2.   

    貌似 你Action对应的Class没找到。检查下class路径写正确没有？
      

  3.   


    确实是找不到，但是我看struts2-src里面的webapp里面的web.xml是这么配的。
    我改成org.apache.struts2.dispatcher.ng.PrepareOperations，这个class能找到，我觉得可能是这个class做filter-class,可是报错严重: Exception starting filter Struts2

  4.   


    我把filter-class改了一下，你帮我看看改了之后是什么问题
      

  5.   

    file:/C:/tomcat/apache-tomcat-6.0.20/webapps/Struts/WEB-INF/classes/struts.xml:30:53 红色部分是什么内容。看看是不是写错了啊。
      

  6.   

    action.UploadAction  你确定UploadAction的包名只有字符串"action"?
      

  7.   

    你写的这个类org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter 。换成这个类试试org.apache.struts2.dispatcher.FilterDispatcher
