Spring 引导附加属性

Question

I am using Spring Boot for creating microservices. By default it uses application.properties for configurations. But I have a requirement to use another property file which is outside of jar file. I tried following options in eclipse JVM arguments while running bootRun from Gradle but still it didn't work.

-Dspring.config.location=c:/another.properties  
-Dspring.config.additional-location=c:/another.properties
-Dspring.config.import=c:/another.properties

I also tried adding the above properties inside application.properties but still @Value annotation added in controller class which refers a property from c:/another.properties is not getting injected.

Answer 1

The spring.config.additional-location should be a folder and the value should end with /

From the documentation:

You can provide default values for your application in application.properties (or whatever other basename you choose with spring.config.name) in one of the default locations. These default values can then be overridden at runtime with a different file located in one of the custom locations.
