Oi Mateus.

Temos os projetos para download em cada aula. É esse projeto que está com erro? Usando eles você poderá ter mais tempo para estudar pois o código já está funcionando.

Ok Lazaro , obrigado.. vou tentar prosseguir utilizando o projeto do curso.

Nessa classe

IConvidadoRepository

Está anotado informando que ele é um bean do Spring? O erro está aprontando nesse caminho.

por Mateus Marquezini
| 39.9k xp | 25 posts

Lazaro, não está anotado pois eu segui seu exemplo, portanto eu não cheguei a anotar conforme você fez.

por Lazaro Prates Junior

Realmente eu confundi. A anotacao que quis falar foi o @Autowired na classe ConvidadoController.

@Autowired
private ConvidadoRepository repository;
por Mateus Marquezini
| 39.9k xp | 25 posts

Sim sim! Estava anotado exatamente assim, e mesmo assim o erro acontecia.

Coloca aí o código dessa interface para eu dar uma olhada.

E a classe de configuracao tbm, por favor

por Mateus Marquezini
| 39.9k xp | 25 posts

Aqui: 

public interface IConvidadoRepository extends CrudRepository<Convidado, Long> {

}
@SpringBootApplication
public class Configuracao {

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

    @Bean
    public DataSource dataSource(){
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName("com.mysql.jdbc.Driver");
        dataSource.setUrl("jdbc:mysql://localhost:3306/listavip");
        dataSource.setUsername("root");
        dataSource.setPassword("root");
        return dataSource;
    }

Caramba, parece tudo certo.

Qual é a versao do Spring q vc está usando? Alguns alunos reportaram problemas com a versao 1.4.1

Eu já nao sei oq pensar sobre esse erro.

por César Augusto

Eu estava com esse mesmo erro... meu pacote era br.com.alura.vips.controller e configuração e convidadoController estava dentro. Fiz varios testes inclusive alterei as versões do SpringBoot para as mais antigas, as mesmas usadas no curso. Não funcionou. Ai eu coloquei Configurações e ConvidadoController no pacote br.com.alura.vips, que era a unica diferença do meu projeto para o projeto da aula, e foi suave... deve ser isso seu problema tb.

muda seu ConvidadoController para o mesmo pacote onde esta o configuracao.class: br.com.alura.listavip
