eclipse struts2 action访问总是404

最近开始学习struts2,建了个练习的项目，然而出手就卡死，index.jsp和success.jsp都可以直接访问，
但是问什么访问helloworld.action就404，跳转直接访问都不行，新手，求大神，妈的我传了6个图，为什么只有1张,我擦，我用手机根本看不到图，

由于看不到图，我再贴一次

</struts>

HelloWorldAction.java

 package cn.itcast.action;

import com.opensymphony.xwork2.ActionSupport;

public class HelloWorldAction extends ActionSupport{
    public String execute() throws Exception{
        System.out.println("dddddd");
        int i=0;
        return "success";
    }
}

贴个源码看看，一般都是路径没有配好

tomcat的server.xml中加了对应的模块的资源映射

可能是path=”/vweb” 与struts2的路径/vweb/view/vweb.action相冲突。
于是修改之：

兄弟，不要structs了，很少用了赶紧转到Spring大家庭吧

1.web.xml中添加struts2的filter

<filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

2.HelloWorldAction.java里写一个helloworld()方法

 public String helloworld(){
         return SUCCESS;
 }

3.struts.xml配置action

  <package name="hello" extends="struts-default">
    <!-- 定义处理请求URL为helloworld.action的Action -->
        <action name="helloworld" class="com.struts.action.HelloWorldAction">
        <!-- 定义处理结果字符串和资源之间的映射关系 -->
            <result name="success">/success.jsp</result>
            <result name="error">/error.jsp</result>
        </action>
    </package>

4.访问路径:项目路径+/helloworld
(因为在web.xml中设置的是/*，所以后面不用.action了)

现在都用springboot了

filter和struts.xlm都适配好了吗，地址栏真的发出了action请求吗看看
