View Code

 

7.新建 controller 目录，在此目录下新建   HelloController 文件，内容如下：

 1 package com.example.demo.controller;
 2 
 3 
 4 import org.springframework.web.bind.annotation.*;
 5 
 6 
 7 /**
 8  * created by why
 9  * @date 20200531
10  *
11  */
12 
13 
14 @RestController
15 public class HelloController {
16 
17     @GetMapping("/hello")
18     public String say(){
19         return "Hello Spring boot";
20     }
21 
22     @GetMapping("add1")
23     public String h1(){
24         return "这add1";
25     }
26 }

 

8.运行 DemoApplication，如图，打开链接 http://127.0.0.1:8080/hello

 

 

 

 

 

9.启动后的端口 是 8080，可以在 application.properties 文件中 添加如图，修改启动端口

 

 

 

1 #端口号
2 server.port=8081
