创建controller
package com.kuang.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class HelloController {
@RequestMapping("/hello")//将请求映射
public String sayHello(Model model){
//向模型中添加属性msg与值，可以在JSP页面中取出并渲染
model.addAttribute("msg","hello,SpringMVC");
//最终会拼接成web-inf/jsp/hello.jsp
return "hello";
}
}
每一个方法都是一个url地址
jsp页面
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>SpringMVC</title>
</head>
<body>
${msg}
</body>
</html>
