Erro logo após criar ProdutoDAO

Oi Ronney, tudo bom?

Parece que não foi encontrado a classe ProdutoDao dentro do pacote com.mkyong.daos. Repare que aqui faz diferença as maiusculas e minusculas. Verifica se sua classe ProdutoDao existe. No curso usamos o nome ProdutoDAO, pode ser algo por ai =)

Abraço!

Olá André. Obrigado pela resposta. Como as importações foram feitas automaticamente creio que não seja essa a fonte do erro, de qualquer forma renomeei a classe, mas mesmo assim persiste

O console me mostra erro em uma versão que não estou usando

<spring.version>4.3.4.RELEASE</spring.version>

Ronney,

Pode postar o seu config no spring ?

Entendo... Verifica pra mim só se sua classe ProdutoDAO está anotada com @Repository?

@Repository
@Transactional
public class ProdutoDAO {

    @PersistenceContext
    private EntityManager manager;

    @RequestMapping("/produtos")
    public void gravar(Produto produto) {
        manager.persist(produto);
    }
}

Essa diferença de versão do Console que não vejo nexo.

O erro estava em Deployment Assembly
