springboot实现多环境配置动态解析 springboot实现多环境配置动态解

springboot实现多环境配置动态解析原文在github，有些相对路径连接不能跳转，如想看原文项目地址 spingboot2.1.3加springcloud G版本,如果觉的不错给个star 谢谢！
在项目整个流程中，开发、测试和线上可能会用不同的环境配置。如果每次都更改配置的话，太过麻烦和笨重。springboot为了方便
提供了spring.profiles.active机制。只要按照application-{profile}.properties建立文件，即可切换不同的配置。
项目测试

在resource下新建三个文件

application-dev.properties //开发环境配置文件 application-rc.properties //线上环境配置文件 application-test.properties //测试环境配置文件

选择使用的配置文件
在resource/application.properties配置文件中添加一下配置项目：

spring.profiles.active=dev

.测试多环境配置
我们分别在

application-dev.properties //开发环境配置文件 application-rc.properties //线上环境配置文件 application-test.properties //测试环境配置文件

文件中添加以下配置：

#端口号 server.port=8081 server.port=8082 server.port=8083

依次修改application.properties文件中的以下配置：

spring.profiles.active=dev、test、rc

修改后依次重启服务。
当使用dev的时候控制台输出一下内容：

2019-02-26 16:35:39.137INFO 6089 --- [main] o.a.catalina.core.AprLifecycleListener: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: [/Users/zwd-admin/Library/Java/Extensions:/Library/Java/Extensions:/Network/Library/Java/Extensions:/System/Library/Java/Extensions:/usr/lib/java:.] 2019-02-26 16:35:39.690INFO 6089 --- [main] o.a.c.c.C.[Tomcat].[localhost].[/]: Initializing Spring embedded WebApplicationContext 2019-02-26 16:35:39.690INFO 6089 --- [main] o.s.web.context.ContextLoader: Root WebApplicationContext: initialization completed in 6071 ms 2019-02-26 16:35:40.082INFO 6089 --- [main] o.s.s.concurrent.ThreadPoolTaskExecutor: Initializing ExecutorService 'applicationTaskExecutor' 2019-02-26 16:35:40.401INFO 6089 --- [main] o.s.b.w.embedded.tomcat.TomcatWebServer: Tomcat started on port(s): 8081 (http) with context path '' 2019-02-26 16:35:40.405INFO 6089 --- [main] c.e.z.s.SpringBootProfilesApplication: Started SpringBootProfilesApplication in 8.212 seconds (JVM running for 9.8)

使用rc的时候控制台输出一下内容：

使用test的时候控制台输出一下内容：

2019-02-26 16:37:07.174INFO 6100 --- [main] o.a.c.c.C.[Tomcat].[localhost].[/]: Initializing Spring embedded WebApplicationContext 2019-02-26 16:37:07.174INFO 6100 --- [main] o.s.web.context.ContextLoader: Root WebApplicationContext: initialization completed in 3532 ms 2019-02-26 16:37:07.505INFO 6100 --- [main] o.s.s.concurrent.ThreadPoolTaskExecutor: Initializing ExecutorService 'applicationTaskExecutor' 2019-02-26 16:37:07.760INFO 6100 --- [main] o.s.b.w.embedded.tomcat.TomcatWebServer: Tomcat started on port(s): 8083 (http) with context path '' 2019-02-26 16:37:07.770INFO 6100 --- [main] c.e.z.s.SpringBootProfilesApplication: Started SpringBootProfilesApplication in 4.898 seconds (JVM running for 6.37)

可以看出在服务启动的时候分别用了不同的配置文件。
