为什么struts2框架的通配符没效果报错了?

Question

struts.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC

    <package name="default" namespace="/" extends="struts-default">
        <action name="helloworld_*" method="{1}" class="com.imooc.action.HelloWorldAction">

            <result name="{1}">/{1}.jsp</result>
        </action>
    </package>

</struts>

HelloWorldAction.java

package com.imooc.action;

import com.opensymphony.xwork2.ActionSupport;

public class HelloWorldAction extends ActionSupport {
    
    public String execute() throws Exception{
        System.out.println("执行action");
        return SUCCESS;
    }
    
    public String add(){
        System.out.println("add");
        return SUCCESS;
    }
    
}

http://127.0.0.1:8080/HelloWorld/helloworld_add.action

HTTP Status 404 - There is no Action mapped for namespace [/] and action name [helloworld_add] associated with context path [/HelloWorld].

报这个错误。。我明明是按照教程的写的啊？哪里出错了？

Answer 1

namespace是不是应该为/HelloWorld

Answer 2

下划线改成中横线试试， 这个框架BUG众多，注意安全。

Answer 3

请问找到问题出在哪了吗？我最近也碰到这个问题了
