我收到以下错误，我用谷歌搜索了很多，得到了许多不同类型的解决方案，但无法解决。

我的 Struts.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
    <constant name="struts.devMode" value="true" />
    <constant name="struts.multipart.maxSize" value="20480000" />
    <constant name="struts.enable.DynamicMethodInvocation" value="false" />

    <package name="default" extends="struts-default">
        <action name="CreateTicket" class="com.ticketservice.CreateTicket">
            <result name="success">Welcome.jsp</result>
            <result name="error">Login.jsp</result>
        </action>


    </package>
</struts>

我的目录结构

在此处输入图像描述

CreateTicket.java

package com.ticketservice;

import com.opensymphony.xwork2.ActionSupport;

public class CreateTicket extends ActionSupport {

    public String execute() {

       return "success";
    }
}

欢迎.jsp

<p>done</p>

登录.jsp

<p>not done</p>

我创建了这个项目来学习 Struts，所以只想看看 struts.xml 到动作类的映射是如何完成的

我能够成功运行 localhost:8080/TicketSystem/index.html。
但是当我运行 localhost:8080/TicketSystem/CreateTicket.action 时。我得到了上述错误..

请帮我解决它。

问候， 马赫什

我认为这是因为您尚未定义名称空间。

尝试这个。

<package name="default" namespace="/" extends="struts-default">

The reason I was getting this error was my build path. My build path was set to other directory not at WEB-INF classes. Doing this change, solved my problem.

可能是您在 struts.xml 文件中犯了错误。所以这里有几种配置xml文件的方法。

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
    <package name="default" extends="struts-default">
        <action name="helloWorld" class="controller.HelloWorld">
            <result name="success">/HelloWorld.jsp</result>

        </action>
    </package>
</struts>

因此，如果您以这种方式执行此操作，只需确保您必须通过操作名称从 jsp 调用操作，您不需要编写会导致错误的 .action。这可能是您问题的理想答案。

我相信这会奏效。
