Error Spring boot call controller "This application has no explicit mapping for / error"

I'm having a problem because I'm learning to use the GET and POST methods using Spring Boot , but only controller I can manage to show on the screen. I am using JSP already configured no aplication.propertties .

spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp

The question is that I have 3 tables in MySQL one and the training and the other and courses

@Controller
public class MainControllerCur {
    @Autowired
    AppCursosRepo appRepocur;

    @RequestMapping("/cursos")
    public ModelAndView doHomeCur(){
        ModelAndView mv = new ModelAndView("cursos");
        mv.addObject("listscur",appRepocur.findAll());
        return mv;
    }

}


@Controller
public class MainControllerTr {
    @Autowired
    AppTreinamentoRepo appRepo;

    @RequestMapping("/treinamento")
    public ModelAndView doHome(){
        ModelAndView mv = new ModelAndView("index");
        return mv;
    }

But here is the employee and the only one who does not generate a server view when I call JSP .

@Controller
public class MainControllerFunc {
    @Autowired
    AppFuncionarioRepo appRepofunc;

    @RequestMapping("/funcionario")
    public ModelAndView doHomeFunc(){
        ModelAndView mv = new ModelAndView("funcionario");
        mv.addObject("listsfunc",appRepofunc.findAll());
        return mv;
    }
}

What is strange and that is exactly the same as the other two only changes the call /funcionario compila normal without no error no error log appears in the console.

The error is always this

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).
/WEB-INF/jsp/funcionario.jsp

If anyone can give me an explanation I'll be grateful.
