在 SpringBoot 中定义所有环境通用的属性的位置? [英] Where to define properties in SpringBoot which are common across all environments?

问题描述

我在资源目录下的 application.properties 中保存了一些所有环境通用的属性(例如 spring.jpa.properties.hibernate.ejb.interceptor).

I have few properties common to all environments (Ex. spring.jpa.properties.hibernate.ejb.interceptor) which I have kept in application.properties under resource directory.

我在基于环境的属性文件中定义了数据库属性，我在启动应用程序时通过命令行从外部传递这些属性:

I have DB properties defined in environment based properties file which I pass externally through command line while starting the app:

java -jar -Dspring.config.location=<path-to-file> mySpringBootProject.jar

但是，当我从外部传递属性文件时，没有设置 spring.jpa.properties.hibernate.ejb.interceptor.

However, spring.jpa.properties.hibernate.ejb.interceptor is not being set when I am passing properties file externally.

我是否需要在外部文件中定义通用属性?或者有没有一种方法可以在一个地方定义它们，在不被覆盖时重复使用?

Do I need to define common properties even in external file? Or is there a way I can define them in a single place which is reused when not overridden?

推荐答案

您可以使用多个配置文件来执行此操作.例如，创建属性文件:

You can use multiple profiles to do this. For example, create property files:

application-dev.properties
application-prod.properties
application.properties

将特定于环境的属性放在 application-${env}.properties 文件中，将常用属性放在 application.properties 中.

Place your environment-specific properties in the application-${env}.properties file and your common properties in application.properties.

有多种方法可以告诉 spring 使用哪些配置文件，例如 --spring.profiles.active 标志.

There are multiple ways to tell spring which profiles to use, for example the --spring.profiles.active flag.

见Spring Boot 文档 了解有关属性文件搜索顺序的更多详细信息.

See the Spring Boot documentation for more details about the property file search order.
