org.apache.struts2.dispatcher.FilterDispatcher is now deprecated。因此，需要将web.xml中的配置做如下修改：

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

改为

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