我需要你的帮助。我有struts.xml和文件Action类的问题。几天前，我的项目很好但是今天当我运行我的项目时，在网络浏览器上出现404错误如下：

HTTP状态404 - /Food/Home.jsp 类型状态报告消息/Food/Home.jsp description请求的资源（/Food/Home.jsp）不可用。 Apache Tomcat / 6.0.16

在Eclipse的控制台中： **

You should look at the error "**Caused by: Action class [controller_user.Login] not found - action - file:/E:/Java/.metadata/.plugins/org.eclipse.wst.server.core/tmp1/wtpwebapps/Food/WEB-INF/classes/struts.xml:7:75**".This is cause for Can not load my Home page or any else page

如果我在struts.xml中清除这些行

         <action name="login" class="controller_user.Login" method="loginAction">
        <result name="success">/User/Registration.jsp</result>
        <result name="failed">/User/LoginFailed.jsp</result>
    </action>

=＆GT;运行我的项目是好的

我不知道如何解决这个问题.Plz帮帮我

您需要将完全限定的类名放在class属性中。 controller_user是您的完整非标准包名吗？它应该是这样的：

<action name = "login" 
       class = "com.foo.bar.controller.user.Login" 
      method = "loginAction" >

如何修复404错误以关注struts 2框架中的Action类（控制器）和struts.xml
