我正在将带有 eclipse 的 Struts 2 项目导出到 webapps 中。

这是我的第一个 strtuts 程序,但在 url localhost:8080/HelloWorldStruts/index.jsp 之后,我在 tomcat 上收到“资源未找到”错误

我的配置:JDK 1.7、Tomcat 7、Struts lib 2.3

我的代码是,

Action 类

package com.home.struts;

public class HelloWorldAction{
private String name;

public String execute() throws Exception {
return "success";
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}
}

索引.jsp

    <%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>Hello World</title>
</head>
<body>
<h1>Hello World From Struts2</h1>
<form action="hello">
<label for="name">Please enter your name</label><br/>
<input type="text" name="name"/>
<input type="submit" value="Say Hello"/>
</form>
</body>
</html>

HelloWorld.jsp

 <%@ page contentType="text/html; charset=UTF-8" %>
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
<title>Hello World</title>
</head>
<body>
Hello World, <s:property value="name"/>
</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>
<constant name="struts.devMode" value="true" />
<package name="helloworld" extends="struts-default">

<action name="hello"
class="com.home.struts.HelloWorldAction"
method="execute">
<result name="success">/HelloWorld.jsp</result>
</action>
</package>
</struts>

最佳答案

在 struts.xml 中,您需要给出映射 index.jsp 页面,因为您的 url 表示 localhost:8080/HelloWorldStruts/index.jsp

示例代码如下,您需要相应修改struts.xml:

<action name="index">
<result>/index.jsp</result>
</action>
