Solution: If you are using @Controller over the Controller class then it will be treated as a MVC controller class. But if you want a special controller used in RESTFul web services then you to use @Controller along with @ResponseBody annotation or you can directly use @RestController over the Controller class. It worked for me as I was getting the same error while creating SpringBoot project with RestFul webservices.

package br.com.SpringApp.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class EventoController {

    @RequestMapping("/cadastroEvento")
    @ResponseBody
    public String form() {      
        return "evento/formEvento"; 
    }

}

or:

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@RestController
public class EventoController {

    @RequestMapping("/cadastroEvento")
    public String form() {      
        return "evento/formEvento"; 
    }

}
