1.案例简单介绍

• 1.1项目结构
  
• 1.2 yml中的内容(不包括application.yml)

2.不借助maven的profile

• 2.1 application.yml中的内容----->这里指定dev为默认环境配置

spring:
  profiles:
    active: dev

• 2.2 打包----->在项目根目录下运行如下命令

mvn clean package -Dmaven.test.skip=true

• 2.3 项目部署 ----->在jar包所在目录运行如下命令

java -jar demo-0.0.1-SNAPSHOT.jar --spring.profiles.active=prod

等号后面等于prod则实际使用的是application-prod.yml文件里的配置,等于test则实际使用的是application-test.yml文件里的配置,以此类推,去掉 --spring.profiles.active=prod,则使用默认的application-dev.yml文件里的配置.

3.借助maven的profile标签

• 3.1 pom.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</project>

• 3.2 application.yml中需要修改成下面的样子

spring:
  profiles:
    active: @[email protected]

• 3.3 打包和部署同不借助maven的profile标签中内容相同.

4. 两者区别

我所知道的区别主要在idea的显示上,描述如下:
