When setting up a Spring boot project, have your Application class (the one that contains the @SpringBootApplication annotation in the base package.

One of the things the @SpringBootApplication does is a component scan. But, it only scans on sub-packages. i.e. if you put that class in com.mypackage, then it will scan for all classes in sub-packages i.e. com.mypackage.*.

If you do not want to do it this way, you can also add a @ComponentScan to a class specifying the root package i.e @ComponentScan("com.mypackage")

I would recommend you have a base package i.e com.mypackage. And within those packages, have your sub-packages. Have you class containing the @SpringBootApplication in that base package.
