No qualifying bean of type [xyz.sample.baremvc.service.CategoriaService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.{quote}

CategoriaService tem anotação do spring?

[evandro_araujo]

Esta sem anotação so spring, qual anotação colocar,

desculpe, estou começando a estudar agora spring.

obrigado

public interface CategoriaService {
	public List<Categoria> listCategoria();

}

public class CategoriaServiceImpl implements CategoriaService {
	
	@Autowired
	private CategoriaDAO categoriaDAO;
	

	@Override
	public List<Categoria> listCategoria() {
		
		return categoriaDAO.listCategoria();
	}

}

[evandro_araujo]

deu certo, inclui a anotação @Service no meu serviço e no meu dao.
