Good afternoon! I'm starting spring studies, I'm following a tutorial the same way, but it returns an error:
Folder structure:
The strange thing is: If I insert the "EventoController.java" into br.com.SpringApp.SpringApp, it works correctly.
package br.com.SpringApp.SpringApp;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class SpringAppApplication {
public static void main(String[] args) {
SpringApplication.run(SpringAppApplication.class, args);
}
}
.
package br.com.SpringApp.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class EventoController {
@RequestMapping("/cadastroEvento")
public String form() {
return "evento/formEvento";
}
}
As requested, I'm adding pom.xml

Can someone tell me where I'm wrong, please?
Make sure that your main class is in a root package above other classes.
When you run a Spring Boot Application, (i.e. a class annotated with @SpringBootApplication), Spring will only scan the classes below your main class package.
So your declaration goes like this
package br.com.SpringApp.SpringApp;
inside this main class i.e SpringAppApplication
package br.com.SpringApp.SpringApp.controller;
name of your controllers i.e EventoController & indexControllers
package br.com.SpringApp.SpringApp.model;
name of your models i.e Evento
After This clean your project and re-run spring boot application;
