Spring-boot 2 中的多个配置文件属性配置

Question

我有一个 spring-boot 2.1。3.RELEASE 应用程序有多个 properties 个文件。

在我的 /src/main/resources 中，我有 my-app.properties 并分析了 my-app-local.properties。

此外，在项目之外我还有另一个配置文件 /config/my-app-local.properties。

此配置的要点是具有以下属性层次结构：

/resources/my-app.properties
/resources/my-app-local.properties
/config/my-app-local.properties

因此，当我尝试运行具有以下参数的应用程序时：

--spring.profiles.active=local --spring.config.name=my-app --spring.config.location=config/my-app.properties

应用程序无法启动，因为它找不到任何 properties 个文件。

但是，此配置和参数在 spring-boot 1.5.19.RELEASE 上运行良好。如何在 spring-boot 2 中实现同样的效果？

使用spring.config.additional-locationdoc

When custom config locations are configured by using spring.config.location, they replace the default locations. For example, if spring.config.location is configured with the value classpath:/custom-config/,file:./custom-config/, the search order becomes the following:

file:./custom-config/
classpath:custom-config/

Alternatively, when custom config locations are configured by using spring.config.additional-location, they are used in addition to the default locations. Additional locations are searched before the default locations. For example, if additional locations of classpath:/custom-config/,file:./custom-config/ are configured, the search order becomes the following:

file:./custom-config/
classpath:custom-config/
file:./config/
file:./
classpath:/config/
classpath:/
