@Component annotation to detect the class like in Springboot

As many people surely know SpringBoot has an @Component annotation to detect a class is a great feature, but I would like to have it implemented in Guice.

I once developed a small example of what it looks like when a component is scanned.

I would consider this feature appropriate, because you can scan and filter out all classes if the class has @Config annotation, for example, and then inject the class automatically.
