Bom dia a todos. Após criar o index,html, criar a classe ConvidadoController e incluir a dependência thymeleaf, estou tomando erro 404. Segue o código na execução da aplicação:

Códigos das classes:

package br.com.alura.listavip;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Configuracao {

    public static void main(String[] args){
        SpringApplication.run(Configuracao.class, args);
    }
}
package br.com.alura.listavip.controller;

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

@Controller
public class ConvidadoController {
    @RequestMapping("/")
    public String index(){
        return "index";
    }
}

Oi Alexander, tudo bem?

de acordo com a linha

main] s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/]}" onto public java.lang.String br.com.alura.listavip.controller.ConvidadoController.index()

o problema não parece ser no Controller

Suspeito que o arquivo index.html esteja no diretório errado, confirma se ele está em "src\main\resources\templates\index.html"

Boa noite Otávio. Depois de "bater cabeça" com o código, resolvi refazer o exercício, no qual funcionou. Provavelmente o problema era realmente o Index.html fora do diretório. Obrigado

Perfeito amigo, fico feliz que tenha dado certo.

Obrigado pelo retorno.

Bons estudos, abraço! ;)
