In my project I have seperate application.yml files for each environments, inside each folder for an environment.

NOTE: Below red color yml file made temporarily, to make the code work. But should remove this after fixing. So what I want is to use separate application.yml file according to environment. Specially I need to use local/application.yml for local development

Below has an example of getting env variables in my project

public class ApplicationProperties {
    private String myServiceUrl;
   // getters setters and nedded stuff

But it doesn't work, since could not find a way to mention the needed environment. Because it is in a seperate folder. All the other examples mention the way to get the yml file inside resource folder, without seperate folders.

Any fix for the issue?

The classic solution is to setup one config file (I prefer properties because I'm sane) and allow for an overrides file to be placed on each installed host.

Spring supports this out-of-the-box.

Like properties in the Java platform, environment variables are key/value pairs, where If the variable is not defined, getenv returns null . Environment variables declared inside a shell command run step, for example FOO=bar make install, will override environment variables declared with the environment and contexts keys.
