I'd like to use dotenv files to configure my Spring Boot application.
What is the best way to do this?
In Ruby or Node world, I just creating .env file and it loads all stuff from there to application environment.
I don't like to create separate profiles for my app etc. I just want to load any environment variables I specified in file into my app.

I have built a proper integration between Spring and dotenv.
Follow this thread to understand the motivation. And then review the library:
Check out the spring-dotenv library here:
https://github.com/paulschwarz/spring-dotenv
The library includes a sample application to show you how to use it, and there you see that the integration with Spring is very natural:
https://github.com/paulschwarz/spring-dotenv/tree/master/application/src/main/resources
I stuck to two principles in designing this library:
- https://12factor.net/config
- Allow your code to be completely unaware of dotenv so that you continue to reference your application.yml/application.properties files using the normal Spring techniques. No funny business.

There's actually a java port of 'dotenv' tool.
