我是第一次使用 Struts2 做我的简单应用程序。
这是我的代码，
操作示例:
package com.demo;
import com.opensymphony.xwork2.Action;
public class ActionExample implements Action
{
@Override
public String execute() {
return SUCCESS;
}
}
成功.jsp:
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!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=UTF-8">
<title>Insert title here</title>
</head>
<body>
Success Page!.........
</body>
</html>
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>
<package name="default" extends="struts-default">
<action name="run" class="com.demo.ActionExample">
<result name="success">/success.jsp</result>
</action>
</package>
</struts>
Web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

我正在通过这个视频链接https://www.youtube.com/watch?v=ATrmHSfh6Tc做
即使我在运行此网址时收到 404 错误:8080/StrutsFirstApplication/run.action
为什么以及如何解决这个问题？
最佳答案
您没有发布您的index.jsp。应该是这样的:
<%@ taglib prefix="s" uri="/struts-tags"%>
...
...
<form action="run">
<s:submit/>
</form>
还有你的 struts.xml 文件:
<?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="default" extends="struts-default">
<action name="run" class="default.ActionExapmle " method="execute">
<result name="success">/success.jsp</result>
</action>
</package>
</struts>
现在，我不知道在 web.xml 文件中使用所有欢迎文件是否正确，请尝试使用以下内容:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
<display-name>Struts 2</display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<filter>
<filter-name>struts2</filter-name>
<filter-class>

</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
