在我的 Spring Boot 应用程序中，我想创建特定于环境的属性文件.我的应用程序在 war 中的打包类型，我正在嵌入式 tomcat 中执行它.我使用 sts 并从 sts 本身执行 main.
In my Spring Boot application, i want to create environment specific properties file. The packaging type of my application in war and i am executing it in embedded tomcat. I use sts and execute the main from sts itself.
在上述情况下，env-value 的值为 local/devl/test/prod
In above case, env-value will have values as local/devl/test/prod
在哪里设置 env-value 文件?对于本地，我可以通过 sts 将其设置为 jvm 参数

如何加载环境特定的属性文件?例如 - 如果我在环境特定的属性文件中设置数据库 uid、pwd、schema 等，在这种情况下，数据源是否能够理解其中的属性?
How to load the environment specific properties file? For ex - if i set the database uid,pwd, schema etc in environment specific property file, in that case will the datasource be able to understand the properties in it?
我可以同时使用 application.properties 和 application-local.properties 文件吗?
Can i use application.properties and application-local.properties file at same time?
推荐答案Spring Boot 已经 支持 profile 基于属性.
Spring Boot already has support for profile based properties.
只需添加一个 application-[profile].properties 文件并使用 spring.profiles.active 属性指定要使用的配置文件.
Simply add an application-[profile].properties file and specify the profiles to use using the spring.profiles.active property.
-Dspring.profiles.active=local这将加载 application.properties 和 application-local.properties ，后者覆盖第一个属性.
This will load the application.properties and the application-local.properties with the latter overriding properties from the first.
