404 sempre

Bom dia Srs, gostaria de ajuda, a aplicação sempre está retornando 404.

Estou esquecendo algo?

Abaixo as configurações

package br.com.alura.listavips;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@SpringBootApplication
@Controller
public class Configuracao {

    @RequestMapping(path="/ola")
    @ResponseBody
    String ola() {
        return "Ola";
    }

    public static void main(String[] args) {
        SpringApplication.run(Configuracao.class, args);

    }

}

Whitelabel Error Page

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