How to override internal configuration file in Spring Correctly?

Question

I have an internal application.yml configuration file located in the resources folder on classpath.

I have an external configuration file: /home/username/config.properties which overrides some fields to run in a server context.

I want the fields in the external config file to override internal file and retain the fields in the internal file if not defined in external file.

The answers suggested Spring - how to override internal config file with external file doesn't work.

For example, the following command doesn't works for me:

java -jar application.jar --spring.config.location=classpath:/,file:///home/minister/config.properties

How do I achieve this desired outcome?

EDIT: This issue only happens on Linux. When I run it with the overriden configuration file on my Windows 10 machine, it works properly.

Answer 1

看起来您有太多/ ，请尝试：

java -jar application.jar --spring.config.location=classpath:/,file:/home/minister/config.properties

Answer 2

You can pass the path to file, relative to the .jar file, for example,

java -jar application.jar -Dspring.config.location=./config/application.properties

or

java -jar application.jar -Dspring.config.location=../common/config

either of these work. Please refer - Spring Documentation for further details on how externalized configuration works.

Hope this helps.
