我认为没有必要在此处粘贴我的代码，因为它正是上面教程链接中所述的代码。除了我取代

  <filter-class>
     org.apache.struts2.dispatcher.FilterDispatcher
  </filter-class>

与

  <filter-class>
     org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
  </filter-class>

正如本回答中提出的那样，无法解决问题：java.lang.ClassNotFoundException: org.apache.struts2.dispatcher.FilterDispatcher 我正在使用struts 2.3.4，但也尝试使用struts 2.2和2.5 - 它们都不起作用。

1 个答案:

答案 0 :(得分：0)

我发现了这个缺陷：我在“部署程序集”中留下了struts 2.5个罐子，因为其他一些帖子在显示其他异常时提出了这个问题。我删除了他们和booom ..现在它的工作原理。 谢谢，亚历山大！
