Can not mapping a controller with a path

Javier :

I have this simple java Spring Boot project without any beans or persistency. I've created multiple packages to separate classes by functionality.

I read that controllers must be inside initial package NameApplication.java. However, I launch project on port 8080 and put next url localhost:8080/hello/grettings show me Whitelabel Error Page but I put localhost:8080 and load index.html

Why doesn't work?

@Controller
@RequestMapping("/hello")
public class BasicController {

    @GetMapping(path = {"/grettings", "/helloworld"})
    public String grettings() {
        return "index";
    }
}

Package structure

Vimukthi_R :

CursoSpringApplication is the starting point of the application. when starting it searches for components such as @Controller, @Service, @Repository and @Component. Usually recommend that you locate your main application class in a root package above other classes. So this CursoSpringApplication class should be placed in most outer package. Change com.globalomnium.axis.maps to com.globalomnium.axis
