What is the best place to store the application.properties file for a Spring boot application?

Question

I have an application.properties file which I have placed at the same level as the src folder. Things are working correctly. But, is this the standard place to keep this file? What is the best practice?

Answer 1

I place them at src/main/resources. Some would prefer src/main/resources/config. When deploying, I put the customized properties at the same folder where the jar is placed. Again, some would prefer the config sub folder.

Spring Boot picks the files from these locations by default.
