目的：

编写第一个 spootboot 程序

完成内容

• 新建 maven 项目
• 配置 pom.xml
• 开发一个 controller 类

  有二个方法，一个问早上好，一个说再见

• 开发主类
• 运行测试，分别测试问早上好和说再见

controller

package com.controller;

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

@RestController
public class HelloController {
    @RequestMapping("/morning")
    public String sayHello(){
        return "早上好";
    }
    @RequestMapping("/bye")
    public String sayBye(){
        return "再见";
    }
}

启动类

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class app {
    public static void main(String[] args) {
        SpringApplication.run(app.class, args);
    }
}
