Environment Specific application.properties file in Spring Boot application
提问by user3534483
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。
- Can i have environment specific properties file like application-${env-value}.properties?
- 我可以拥有特定于环境的属性文件，例如 application-${env-value}.properties 吗？
In above case, env-value will have values as local/devl/test/prod
在上述情况下，env-value 的值将是 local/devl/test/prod
Where to set the env-value file? For local, i can set it as the jvm argument through sts
Who reads the application.properties in Spring Boot application.
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?
Can i use application.properties and application-local.properties file at same time?
在哪里设置环境值文件？对于本地，我可以通过 sts 将其设置为 jvm 参数
谁读取 Spring Boot 应用程序中的 application.properties。
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、模式等，在这种情况下，数据源是否能够理解其中的属性？
我可以同时使用 application.properties 和 application-local.properties 文件吗？

Spring Boot already has supportfor profilebased properties.
Simply add an application-[profile].propertiesfile and specify the profiles to use using the spring.profiles.activeproperty.
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。
-Dspring.profiles.active=local
This will load the application.propertiesand the application-local.propertieswith the latter overriding properties from the first.
这将加载application.properties和application-local.properties，后者覆盖第一个属性。

Yes you can. Since you are using spring, check out @PropertySourceanotation.
是的你可以。由于您使用的是 spring，请查看@PropertySource注释。
Anotate your configuration with
注释您的配置
@PropertySource("application-${spring.profiles.active}.properties")
You can call it what ever you like, and add inn multiple property files if you like too. Can be nice if you have more sets and/or defaults that belongs to all environments (can be written with @PropertySource{...,...,...} as well).
您可以随意称呼它，如果您也喜欢，还可以添加多个属性文件。如果您有更多属于所有环境的集合和/或默认值（也可以用 @PropertySource{...,...,...} 编写），那就太好了。
@PropertySources({
@PropertySource("application-${spring.profiles.active}.properties"),
@PropertySource("my-special-${spring.profiles.active}.properties"),
@PropertySource("overridden.properties")})
Then you can start the application with environment
然后您可以使用环境启动应用程序
-Dspring.active.profiles=test
In this example, name will be replaced with application-test-properties and so on.
在此示例中，名称将替换为 application-test-properties 等。

we can do like this:
我们可以这样做：
in application.yml:
在application.yml 中：
spring:
profiles:
active: test //modify here to switch between environments
include: application-${spring.profiles.active}.yml
in application-test.yml:
在application-test.yml 中：
server:
port: 5000
and in application-local.yml:
在application-local.yml 中：
server:
address: 0.0.0.0
port: 8080
then spring boot will start our app as we wish to.
然后 spring boot 将按照我们的意愿启动我们的应用程序。
