E ai Amigos Hipsters…

Eis que eu estava programando ontem a noite e me deparei com o seguinte erro numa aplicação do Spring Boot…

Segundo o erro, é da do CommandLineRunner na Aplicação Master do Spring Boot, destrinchei todas as classes do meu projeto e não encontrei o erro.

Quem pode me dar uma orientação melhor?

Julgando pelo log, o erro é um NPE, e pelo que parece, está sendo executada uma migration do banco de dados, mais especificamente destruindo tudo e recriando, chegou a verificar os inserts de categoria, ambos estão sendo logados com null?
Qualquer coisa habilite o nível de log DEBUG para receber mais detalhes do que pode estar ocorrendo.

Apenas o ID esta sendo mandado como null, pois é cadastros de dados para leitura de testes.

vou checar isso tudo com calma e ai te respondo.
Beleza @Jonathan_Medeiros? Mais uma vez obrigado pela atenção!!

Então @Jonathan_Medeiros, acabei de descobrir o problema…

@SpringBootApplication
public class CursoSpringbootApplication implements CommandLineRunner {
	
	@Autowired
	private CategoriaRepository categoriaRepository;
	
	@Autowired
	private ProdutoRepository produtoRepository;
	
	public static void main(String[] args) {
		SpringApplication.run(CursoSpringbootApplication.class, args);
	}

Eu tinha esquecido de adicionar o " @Autowired " em um dos Repositories que adicionei e nem tinha reparado rs.

Mais uma vez muito obrigado pela atenção e a sugestão!!

Abraços @tncardoso
