Question

我想使用struts2构建一个Web应用程序并将我的网页部署在服务器上。

我从Youtube上的教程开始。链接。

并且我收到错误为原始服务器找不到目标资源的当前表示，或者不愿意透露其存在。

我使用Java版本8 带有Eclipse版本2019-03 我的运行时服务器是Apache Tomcat v9.0。操作系统是Windows 10。

教程链接： https://www.youtube.com/watch?v=f46WEeM8HTA&list=PLB7BB551126EDD5E0

我写的代码如下：

struts.xml（写在下面）

<?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>
 <package name="Struts2.1" extends="struts-default" >
<action name="getTutorial" class="org.yat.javabrains.action.TutorialAction">
<result name="success">/success.jsp</result>
<result name="error">/error.jsp</result>
</action>
</package>
</struts>

web.xml文件如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd" id="WebApp_ID" version="4.0">
  <display-name>Struts2.1</display-name>
<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>

</web-app>

TutorialAction.java

package org.yat.javabrains.action;

public class TutorialAction {

     public String execute()
     {
      String success="success";
      return success;
     }  


}

：success.jsp的代码

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Struts2 tutorial</title>
</head>
<body bgColor="lightblue">
Hello world!!!This is Struts 2 tutorial
</body>
</html>

error.jsp的代码

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
Error!!!!
</body>
</html>


im getting the output as
[enter image description here][1]

The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.



 Could someone please tell me what is going wrong.
I intially thought it to be an error due to some struts jar error.
I've tried with the srtuts(v2.5.20, v2.3.27,v2.3.30) 
but all gave the same error.

即使我已经编写了正确的代码也会出现错误源服务器未找到目标的当前表示形式
