如何在Spring-Boot生产期间覆盖application.properties？ [英] How to override application.properties during production in Spring-Boot?

问题描述

我正在使用spring boot和 application.properties 在开发期间通过 @Configuration @Profile（dev）选择数据库。

I'm using spring boot and application.properties to select a database during development by @Configuration @Profile("dev").

spring.profiles.active=dev
spring.config.location=file:d:/application.properties

在制作期间，我想在应用程序上下文之外创建一个文件应加载，然后激活不同的配置文件，使用d：/application.properties：

During production I'd like to create a file outside of the application context that should be loaded and then active a different configuration profile, with d:/application.properties:

spring.profiles.active=production

结果：当我启动应用程序时，配置仍然是 dev ，因此不会考虑生产属性文件的其他位置。我错过了什么吗？

Result: when I start the app, the configuration is still dev, so somehow the additional location of the productive properties file is not taken into account. Am I missing anything?

spring boot 1.1.0.BUILD-SNAPSHOT

spring boot 1.1.0.BUILD-SNAPSHOT

注意：这个问题是 NOT 关于 tomcat 。

Note: this question is NOT about tomcat.

推荐答案

我知道你问怎么做。

但答案是，你不应该这样做。

But the answer is, you should not do this.

你可以拥有application.properties应用程序 - default.properties application-dev.properties等

You can have application.properties application-default.properties application-dev.properties etc

您可以通过命令行参数将配置文件切换到jvm

you can switch profiles by command line args to the jvm

你可以在测试时使用@TestPropertySource覆盖一些东西

you can override some things at test time using @TestPropertySource

理想情况下，一切都应该在源代码控制中，这样就不会有任何意外 - 你怎么知道这些属性在哪里？您的服务器位置，以及缺少的位置。如果开发人员介绍新内容会发生什么。

Ideally everything should be in source control so that there are no surprises - how do you know what properties are sitting there in your server location, and which ones are missing. What happens if developers introduce new things.

Spring boot已经为你提供了足够的方法来做到这一点。

Spring boot is already giving you enough ways to do this right.
