Spring Boot 2.4.0.M2 has just been released, and it brings with it some interesting changes to the way that application.properties and application.yml files are loaded.

If your applications use the fairly typical setup of only using a single application.properties or application.yml file, then you’ll probably not notice any difference. If, however, you have applications that use more complex setups (such as profile specific properties), you might want to read on to learn about what we’ve changed and why.

Why We’re Making These Changes

With recent versions of Spring Boot we’ve been working hard…
