springboot 配置檔案之多環境配置

1. application.properties

在父配置檔案(application.properties)中啟用要選用的子配置檔案

spring.profiles.active=dev

子配置檔案 dev 內容如下:

server.port=9996
spring.application.name=idea-first-springboot
spring.datasource.url=jdbc:mysql://localhost:3306/boxcloud?useUnicode=true&characterEncoding=utf-8&useSSL=false&generateSimpleParameterMetadata=true
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

teacher.name=hh
teacher.sex=man

子配置檔案 master 內容如下:

server.port=9996
spring.application.name=idea-first-springboot
spring.datasource.url=jdbc:mysql://localhost:3306/boxcloud?useUnicode=true&characterEncoding=utf-8&useSSL=false&generateSimpleParameterMetadata=true
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

student.name=anna
student.age=18
student.content:name:${student.name},age:${student.age}

說明:

子配置檔案命名格式要滿足: application-***.properties 的格式

2. application.yml

yml 配置多環境只需要一個配置檔案,yml配置檔案有區分的能力

spring:
  profiles:
    active: master
---
spring:
  profiles: dev
server:
  port: 9999
teacher:
  name: aa
  sex: woman
---
spring:
  profiles: master
server:
  port: 9998
teacher:
  name: dd
  sex: man

 注意:yml 配置的形式需要有層次,“:”後面必須有一個空格

spring:
  profiles:
    active: dev

不能寫成:spring.profiles.active:dev
