How to override SpringBoot config external file to classpath file?

I would like override SpringBoot external's some config into classpath file., when I run jar by command line.

classpath -> application-config.yaml (Not application.yaml)

server:
  port: 8080
  servlet:
    contextPath: /myapp
test-message: this config no need to export as external config.

external -> D:/test/application-config-override.yaml

server:
  port: 9090

command

java -Dspring.config.location=classpath:application-config.yaml,file:///D:/test/application-config-override.yaml -jar myapp.jar

when I run above commend, the application is running 8080, contextPath is "myapp". My expected one is http://localhost:9090/myapp

But, if I put all of same config structure of application-config.yaml into application-config-override.yaml as below

application-config-override.yaml

server:
  port: 9090
  servlet:
    contextPath: /yourapp
test-message: this config no need to export as external

Application is running 9090, contextPath is "yourapp".

How to override SpringBoot external some config into classpath file? I am using 2.5.4.

I don't want to export unnecessary some configs to external. I would like to marge and override by order.

Solution

  • Try to provide both spring.config.additional-location and spring.config.name like this,

    -Dspring.config.additional-location=D:///test/ -Dspring.config.name=application-config,application-config-override
