spring yml file for specific environment
提问by Amar Dev
I have 3 ymlfiles namely
我有3个yml文件
application-default.yml-> default properties, should be available in all profilesapplication-dev.yml-> properties only for dev profileapplication-prod.yml-> properties only for prod profile
application-default.yml-> 默认属性，应该在所有配置文件中可用application-dev.yml-> 仅用于开发配置文件的属性application-prod.yml-> 仅适用于 prod 配置文件的属性
When I start my boot application by passing the -Dspring.profiles.active=dev,I am able to access the application-dev.ymlspecific properties.
But I cant get the properties defined in the application-default.ymlfiles.
Following is my application-dev.ymlfile:
当我通过传递 启动我的启动应用程序时-Dspring.profiles.active=dev，我能够访问application-dev.yml特定的属性。但我无法获得application-default.yml文件中定义的属性。以下是我的application-dev.yml文件：
Spring:
profiles:
include: default
spring.profiles: dev
prop:
key:value

I was able to solve my problem, here is what I did.
我能够解决我的问题，这就是我所做的。
Created a file application-common.yml, put the common properties there. Then in the application-{env}.yml files I put this on the top.
创建了一个文件 application-common.yml，把公共属性放在那里。然后在 application-{env}.yml 文件中我把它放在最上面。
spring:
profiles:
include: default
Since I dont need to ever load the default profile specifically, this works for me!!!
由于我不需要专门加载默认配置文件，这对我有用！！！

Just rename the application-default.ymlfile to application.ymland will work as you expect.
只需重命名该应用程序default.yml文件application.yml和您预期会工作。
Explanation
解释
According to the description in the docs, a file called application-{suffix}.ymlis activated when you run your application with the profile which name matches with the suffix. In addition, the main application.ymlis loaded by default so it's the perfect place to put common properties for all profiles. Alternatively, if you want to keep the name of your file as application-default.yml you can pass two profiles to your Spring Boot application:
根据文档中的描述，当您使用名称与后缀匹配的配置文件运行应用程序时，会激活名为application-{suffix}.yml的文件。此外，主application.yml是默认加载的，因此它是放置所有配置文件通用属性的理想场所。或者，如果您想将文件名称保留为 application-default.yml，您可以将两个配置文件传递给您的 Spring Boot 应用程序：
-Dspring.profiles.active=default,dev
This way you will activate two profiles and both properties files will be loaded.
这样您将激活两个配置文件，并且将加载两个属性文件。

What I do is:
我要做的是：
Put common settings in application.xml, and in this file add:
将常用设置放入application.xml，并在此文件中添加：
spring:
profiles:
active: dev, pro, xxx...
all the profiles you want to activate.
您要激活的所有配置文件。
So that you just edit this file to switch environment.
这样您只需编辑此文件即可切换环境。
Remember that external files procedes, so you can leave another application.xmloutside of the WAR to activate dev/pro/... environment instead of editing this file every time. Be sure to check the documentation:
请记住，外部文件会继续运行，因此您可以application.xml在 WAR 之外保留另一个文件来激活dev/ pro/... 环境，而不是每次都编辑此文件。请务必检查文档：
