文章介绍了在企业项目开发中，如何利用Maven的环境隔离功能来管理不同环境（如开发、测试、生产）的配置。通过创建不同的配置文件，设置Maven的profiles，并在SpringBoot应用中动态激活所需配置，实现无缝切换。

1.简介
在企业项目开发时，开发环境和生产环境的配置信息是不一样的，比如连接MySQL、Redis等配置，如果每次部署或者开发都要更改配置文件就太麻烦了，这时就可以使用Maven的环境隔离。

2.隔离
(1).创建配置文件
在这里插入图片描述

(2).pom配置

            </properties>
        </profile>
    </profiles>

</project>

(3).在SpringBoot配置文件中配置需要启用的配置文件

server:
  port: 8080

spring:
  profiles:
    active: @build.profile.id@

(4).选择prd配置启动项目
在这里插入图片描述
可以看到，激活配置项为prd。
