4.启动即可

最简单的启动起来了

5.试着写一个controller访问一下

package com.sxd.firstdad.controller;

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

/**
 * @Author: SXD
 * @Description:
 * @Date: create in 2019/10/9 15:37
 */
@RestController
public class FirstController {

    @RequestMapping(value = "/myTest",method = {RequestMethod.GET,RequestMethod.POST})
    public String myTest(){
        System.out.println("进入Controller");
        return "访问成功 ";
    }
}
