          </plugin>
      </plugins>
  </build>
</project>

2、Application.class代码编写

package com.zkk.springBootStudy;

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

@SpringBootApplication
public class FirstApplication {

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

3、application.yml

spring:
 profiles:
  active: prod

server:
 port: 8081
 context-path: /study

4、helloword例子

package com.zkk.springBootStudy;

import org.json.JSONException;
import org.json.JSONObject;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import com.zkk.springBootStudy.model.ModelRes;

@RestController
public class HelloWorld {

//    @RequestMapping(value ="/hello", method = RequestMethod.GET)
    @GetMapping(value="/hello")
    public String say(@RequestParam("id") String id){
        return "id:" + id;
    }
}
