Olá pessoal,
Eu estou estudando a novo aposta da Caelum FJ-28, com base no vraptor-blank-project-3.3.0.
Bom até o momento eu não estava com muita dificuldade o problema foi quando cheguei no Cap. 15 no Exercícios: Transaction Manager.
Eu não sei o que aconteceu que agora só o Home do meu projeto funciona!
Vou calocar aqui meus arquivos seguido do Log erro!

para usar o Spring-Transactional, vc precisa usar interfaces/implementações nas classes que têm @Transactional

no eclipse faça o seguinte:
abra a classe ProdutoDao, digite Ctrl+3 extract interface, dê um nome pra interface, selecione os métodos pertinentes e deixe marcado o checkbox “use supertype where possible”

assim vai funcionar tranquilo.

Lucas, eu fiz o que vc falou mais agora apareceu isso:

ProdutoDao é a classe ou a interface?

a classe está anotada com @Component?

package br.com.caelum.goodbuy.dao;

import br.com.caelum.goodbuy.modelo.Produto;

public interface SpringTransactional {

	@Transactional
	public abstract void atualiza(Produto produto);

	@Transactional
	public abstract void remove(Produto produto);

	@Transactional
	public abstract void salva(Produto produto);

}

package br.com.caelum.goodbuy.dao;

não precisa do @Transactional na interface…

no controller vc está recebendo ProdutoDao ou SpringTransactional?

o melhor seria a interface se chamar ProdutoDao, e a implementação HibernateProdutoDao, ProdutoDaoImpl ou DefaultProdutoDao. E o controller recebendo a interface no construtor.

Lucas muito obrigado!
Funcionou!

Agora vou ter que fazer em todas as DaoS a mesma coisa?

Lucas_Cavalcanti
Lucas_Cavalcanti

se vc quiser usar o @Transactional nos daos sim.

é uma boa prática fazer interface/implementação, principalmente se vc for usar a classe como dependência de outra. Isso diminui o acoplamento entre as classes e torna mais fácil testar, mudar a implementação, usar implementações controladas, etc.

Lucas, depois vou tentar trabalha com base no seu post: Possibilidades de design no uso do seu Generic DAO.

E agora, como fecha esse post aqui?
