2. DispatcherServlet从Spring6 才开始使用jakarta.servlet.http.Servlet
3. Spring6 需要JDK 17+

4. Controller
package com.ityj.springmvc.controller;import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;@Controller
public class HelloController {@GetMapping("/hello")public String hello() {System.out.println("hello");return "hello";}
}<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>Hello</title>
</head>
<body>
Hello
</body>
</html>
6. 部署到Tomcat并测试
