        百度了，能用的解决方案都用了，错误一个接一个的来，索性谷歌，发现答案和百度是一模一样的。
        哥们，帮小弟解决一下吧！我实在不想去搜狗.....太么人性了！
[最优解释]

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

[其他解释]
直接参考struts包里面的demo重新搭建一次，现在你的那个FilterDispatcher已经不用了，换成楼上的尝试一下

  可以参考一下struts2的文档配置 org.apache.struts2.dispatcher.FilterDispatcher这个类好像不在struts中使用啦

这是我写struts的两个配置文件内容，能运行。

struts2中使用啦

谢谢楼上各位哥们的热心回复！我重装Tomcat 然后再把拦截器改成一楼的写法就好了！！
