application.yml application.properties priority

There is a question on stackoverflow is: Can application.properties and application.yml be mixed?

Spring Boot has done a lot of work to simplify configuration, but it's still quite complex!
There are as many as 17 external configuration methods supported, which is flexible, but flexibility means increased complexity.

Let's just talk about the priorities of the two files, application.yml and application.properties

If the application.properties file exists in your project,
Then the application.yml file is just a decoration.

Why do you say that?
I configured in the application.properties file:
server.port=8085

In the application.yml file, the following is configured:

server:

port: 8086

Start the project, console output:

main] s.b.c.e.t.TomcatEmbeddedServletContainer : Tomcat started on port(s): 8085 (http)

This is fully illustrated.
