Answer 1

如果你用的是Struts2试一试在web.xml中
<filter>
    <filter-name>struts2</filter-name>
     <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>

Answer 2

你加点东西了。
<package name="strutspackage" extends="struts-default" namespace="/">
<action name="user" class="com.gridedu.action.UserAction">
<result>/index.jsp</result>
</action>
  </package>
