Question

enter image description here 当输入网址= http://localhost:8080/helloworld/home时，它表示请求的资源不可用。我无法弄清楚问题是什么。我在互联网上尝试了几乎所有的解决方案，但没有任何效果。

控制器类： -

package com.helloworld;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

@Controller

public class HelloWorldController {

    @RequestMapping("/home")
    public String homepage(){
        System.out.println("hello world!!!");
        return "home";
    }
}

针对home.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>
Hey Dude
</body>
</html>

   <display-name>Spring MVC Application</display-name>

   <servlet>
      <servlet-name>Hello</servlet-name>
      <servlet-class>
         org.springframework.web.servlet.DispatcherServlet

您好-servlet.xml中

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"  
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
    xmlns:p="http://www.springframework.org/schema/p"  
    xmlns:context="http://www.springframework.org/schema/context"  
    xsi:schemaLocation="http://www.springframework.org/schema/beans  
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd  
http://www.springframework.org/schema/context  
http://www.springframework.org/schema/context/spring-context-3.0.xsd"> 

<context:component-scan base-package="com.helloworld"/>

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"></property>
<property name="suffix" value=".jsp"></property>
</bean>

</beans>
