Do you know why IntelliJ IDEA Community Edition 2022.02.1 does not see properties in aplication.properties? enter image description here Does the compiler recognize and use them even though it cannot see them? If you need more information about this problem ask me I will write back as soon as possible.

This is my pom.xml

Spring & Spring Boot assistance comes with IntelliJ IDEA Ultimate which can detect all your Beans (along with its usages and injections), Rest Controller Endpoints, Application Properties (along with the classes that use those properties), Spring relevant auto completions, etc. The said features are not available in IntelliJ IDEA Community Edition which is why you see those application properties as unused. Still, in reality, it is being used and your application should pick them up just fine (assuming you've set up things correctly).

These missing features however should not stop you from developing Spring Boot (or any JVM frameworks for that matter) applications using IntelliJ IDEA Community Edition.
