你是否為SpringBoot一個功能多個yml和多個properties檔案區分不同執行環境配置，經常為這些配置檔案的管理而頭疼，現在通過這篇文章，將徹底解決你的煩惱，這篇文篇介紹，怎麼通過yml檔案構建多文件塊，區分不同環境配置，自由切換不同環境啟動專案，一個配置檔案搞定。

準備工作

環境：

windows
jdk 8
maven 3.0
IDEA

修改YML配置

#選擇哪一個環境的配置
#這裡可以在每個環境配置redis，資料庫（mysql），訊息（kafka）等相關的元件的配置
spring:
  profiles:
    active: prod

#文件塊區分為三個---
---
server:
  port: 8081
spring:
  profiles: test

#文件塊區分為三個---
---
server:
  port: 8082
spring:
  profiles: test

#文件塊區分為三個---
---
server:
  port: 8083
spring:
  profiles: prod

建立啟動類

@SpringBootApplication
public class SpringBootConfigApplication {

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

至此YML多文件塊多環境配置是不是非常簡單，切換環境只需要修改

spring:
  profiles:
    active: prod

中active對應的環境的值即可。
