Answer 1

You can explicitly specify your application properties location by setting the program arguments with as :

--spring.config.location=your_properties_path

Answer 2

This is not a sufficient description for your problem, where did you put the application.yml file ? if you are in a maven projet project, you should put it under src/main/resources folder.

Also I'm not sure if spring is able to interpret .yml file extension of your file, try to change it to application.yaml instead.

Note from spring.io :
