Maven与SpringBoot多环境兼容

 

Maven的pom.xml设了多环境，Boot的application.yml也设置了多环境

要使得Boot读取到Maven中的配置就需要在Maven的pom.xml中设置<profile.active>

pom.xml中主要修改这里

 

 

 pom.xml全部

application.yml

#设置启用的环境
spring:
  profiles:
    active: ${profile.active}

---
#不过时的写法
#开发
spring:
  config:
    activate:
      on-profile: dev
server:
  port: 80
---
#过时的写法,但也能用
#生产
spring:
  profiles: pro
server:
  port: 81
---
#测试
spring:
  profiles: test
server:
  port: 82
---

 

程序启动时

Boot的application.yml就修改为Maven的pom.xml配置

 

 

 注意要使得application.yml的${profile.active}被正确解析，在pom.xml添加 maven-resources-plugin 插件才行

多说一句，如果这个插件标红，要加入<version>才行，version与org.springframework.boot对于一致即可
