Question

我有这个简单的hello world spring appplication通过spring工具编码，当我想访问jsp时，我得到错误404。我一步一步地按照主要教程进行操作，但仍未找到解决此问题的任何方法。有什么建议吗？

**Hello Controller**

package com.pluralsight.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller 
public class HelloController {

@RequestMapping(value="/greeting")   //url navigation
public String sayHello(Model model){  // model = mapmash for servlet
    model.addAttribute("greeting","Hello World");
    return "hello";
}
}

**hello.jsp**

<%@ 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>
<h1>${greeting}</h1>
</body>
</html>
