I can't map the Rest Endpoint with Spring Boot - postgresql

Question

I'm starting work with SpringBoot in a new project, and I'm trying create a environment like a base.
So, I'm mappping the endpoins, but when I iniciality the server, I can see that those endpoint don't load.
My Rest Class
#RestController
#RequestMapping("/estados")
public class EstadoResource {
#Autowired private EstadoRepository estadoRepository;
#RequestMapping(value = "/criar", method = RequestMethod.GET)
public String criar() {
Estado estado = new Estado();
estado.setNome("Rio de Janeiro");
return "Rest Funcionando";
}
}
I tried with #GetMapping and didn't work too.

Someone know what I can be doing it wrong?
Thanks!
Edit1: When I tried to access localhost:8080/estados/criar show the springboot white page with 404 error
Edit2: Guys, after some tests, I was able to make it work, I percebed that if I put the Main Spring Class in the same package of Controllers the system map the endpoints correctly, but I believe that is not ideal, someone know how can I configure it?
