springboot外部配置-特定于配置文件的配置 [英] springboot external configuration - profile specific configuration

问题描述

根据SpringBoot文档，配置顺序为:

According to the SpringBoot documentation, the order of configuration is as:

打包的jar之外的特定于配置文件的应用程序属性(application- {profile} .properties和YAML变体)

Profile-specific application properties outside of your packaged jar (application-{profile}.properties and YAML variants)

打包在jar中的特定于配置文件的应用程序属性(application- {profile} .properties和YAML变体)

Profile-specific application properties packaged inside your jar (application-{profile}.properties and YAML variants)

打包的jar之外的应用程序属性(application.properties和YAML变体).

Application properties outside of your packaged jar (application.properties and YAML variants).

打包在jar中的应用程序属性(application.properties和YAML变体).

Application properties packaged inside your jar (application.properties and YAML variants).

在我的项目中，我有一个名为"prod"的个人资料，以及以下文件:

On my project I have a profile called "prod" and the following files:

• application.yml(在jar内)
• application-prod.yml(在jar中)

我还想使用外部文件覆盖某些属性.由于根据文档，外部application.yml将被内部application-prod.yml覆盖，因此我需要确保将外部文件视为profile specific配置文件.

And I also want to override some of the properties using an external file. Since according to the docs, an external application.yml will be overridden by the internal application-prod.yml, I need to make sure that the external file is considered as a profile specific config file.

我尝试使用:

-Dspring.config.location=<my path>/application-prod.yml

而且我也尝试过:

-Dspring.config.location=file:<my path>/application-prod.yml

在所有情况下，我都从内部 application-prod.yml

In all cases I get the value from the internal application-prod.yml

如果我完全删除了内部配置文件，那么我会从外部获取值(所以我知道配置会拾取该文件).

If I totally remove the internal config file then I get the value from the external (so I know that the config picks up the file).

我了解到，该外部文件被视为与通用application.yml等效，而不是特定于个人资料的文件.

I understand that this external file is considered as the equivalent to the generic application.yml and not a profile specific.

如何将其配置为配置文件特定的外部配置?

How can I configure it to be considered as a profile specific external config?

推荐答案

找到了答案:

您需要从外部使用Directory来设置特定于配置文件的配置文件，而不是直接使用该文件，并且该文件必须以/结尾.因此必须是:

You need to use a Directory externally to set the profile specific configuration files, not using the file directly and it needs to end in /. So it has to be:

-Dspring.profiles.active=prod

-Dspring.config.location=/<some-path>/config/(任何以/结尾的路径)

-Dspring.config.location=/<some-path>/config/ (any path that ends in /)

其中有一个:

application-prod.yml
