VRaptor - Como interceptar um StaleObjectStateException

tudo bom pessoal
preciso interceptar o StaleObjectStateException do Hibernate
pra isso criei um Interceptor mas ele tah engolindo a exceção

@Override
	public void intercept(InterceptorStack stack, ResourceMethod method, Object object) throws InterceptionException {
		try {
			stack.next(method, object);
		} catch (StaleObjectStateException exception) {
			// Preciso cair aqui...
		} catch (Exception exception) {
			// Sempre cai aqui...
		}
	}

e pelo objeto “Exception exception” eu não consigo chegar na causa da exceção (no caso o StaleObjectStateException)
alguma dica?
obrigado

Se você debugar, qual exception acontece?

CommanderShepard 13 de jun. de 2011

tudo bom Rafael
abaixo um print do Inspect do Eclipse com o objeto “Exception exception”

Rafael_Guerreiro 13 de jun. de 2011

Ele não está dando um StaleObjectStateException…

Ou o RollbackException extends StaleObjectStateException?

CommanderShepard 13 de jun. de 2011

o StaleObjectStateException acontece
ele é printado na stack trace, o funcionamento dele tá ok (estamos testando a concorrência e até agora tudo ok)
o problema tá sendo pegar ele no Interceptor pra jogar um erro legal pro usuário
senão me engano a árvore do StaleObjectStateException é “StaleObjectStateException->StaleStateException->HibernateException->RuntimeException->…” e o RollbackException é “javax.algumacoisa”

Lucas_Cavalcanti 13 de jun. de 2011

o problema é que antes de chegar em vc está passando pelo interceptor de transações, e ele tá tentando dar o commit de uma transação que já estava marcada como rollback only.

use a última versão do VRaptor e anote seu interceptor da StaleObject com:

@Intercepts(after=HibernateTransactionInterceptor.class)

assim a exception vai passar antes (na volta) pelo seu interceptor

tudo bom Lucas
implementando sua sugestão está gerando uma exceção

abaixo o código do meu Interceptor

package br.com.meuprojeto.web.interceptors;

import javax.servlet.http.HttpServletRequest;

import org.hibernate.StaleObjectStateException;
import org.springframework.beans.factory.annotation.Autowired;

import br.com.caelum.vraptor.InterceptionException;
import br.com.caelum.vraptor.Intercepts;
import br.com.caelum.vraptor.Result;
import br.com.caelum.vraptor.core.InterceptorStack;
import br.com.caelum.vraptor.interceptor.Interceptor;
import br.com.caelum.vraptor.ioc.RequestScoped;
import br.com.caelum.vraptor.resource.ResourceMethod;
import br.com.caelum.vraptor.util.hibernate.HibernateTransactionInterceptor;

@Intercepts(after = HibernateTransactionInterceptor.class)
@RequestScoped
public class StaleObjectStateExceptionInterceptor implements Interceptor {

	private Result result;
	private HttpServletRequest request;

	@Autowired
	public StaleObjectStateExceptionInterceptor(Result result, HttpServletRequest request) {
		this.result = result;
		this.request = request;
	}

	@Override
	public boolean accepts(final ResourceMethod method) {
		if (method.getMethod().getName().equals("saveOrUpdate")) {
			return true;
		}

		return false;
	}

	@Override
	public void intercept(InterceptorStack stack, ResourceMethod method, Object object) throws InterceptionException {
		try {
			stack.next(method, object);
		} catch (StaleObjectStateException e) {
			System.out.println("Testando StaleObjectStateException...");
		} catch (Exception e) {
			System.out.println("Testando Exception...");
		}
	}

}

e outra dúvida… o HibernateTransactionInterceptor é um open session in view?

obrigado

Lucas_Cavalcanti 13 de jun. de 2011

desculpe, vc está usando jpa… o interceptor é JPATransactionInterceptor. Use:

@Intercepts(after=JPATransactionInterceptor.class)

e sim, ele é um OpenSessionInView.

Detalhe importante: vc está controlando transações ou é o VRaptor que está fazendo isso? se for você isso que eu falei não vai funcionar

CommanderShepard 13 de jun. de 2011

quem está controlando as transações é o Spring
será que tem jeito de pegar o StaleObjectStateException via Interceptor?
ficaria perfeito pra mim pois já tenho um Interceptor para erros genéricos que faz isso (o que recebe o objeto “Exception exception”)
aí seria apenas adicionar mais um catch no try

Lucas_Cavalcanti 13 de jun. de 2011

vc está usando o @Transactional então, certo?

o problema é que ele tá escondendo a exception, não sei se vc vai conseguir capturá-la de um jeito legal…
pq vc quer fazer isso mesmo? vc vai conseguir se recuperar do erro? ou é só logging?

CommanderShepard 13 de jun. de 2011

isto
estou utilizando "@Transactional(rollbackFor = Exception.class, propagation = Propagation.REQUIRED)"
eu vou me recuperar do StaleObjectStateException e mostrar uma mensagem pro usuário: "Este registro foi atualizado por outro usuário, recarregue os dados e tente novamente."
essa vai ser a mensagem padrão pra quando algum erro de concorrência acontecer

e eu tb não to conseguindo pegar o StaleObjectStateException direto do meu Controller

// No meu Controller, no método de salvar...
	try {
		super.saveOrUpdate(objeto);
	} catch (Exception e) { // Esperando um StaleObjectStateException aqui.
		e.printStackTrace(); // Apenas o TransactionSystemException e o RollbackException.
	}

tah foda

Lucas_Cavalcanti 13 de jun. de 2011

tenta fazer esse try…catch mais perto da session/entityManager… por exemplo no dao ou coisa do tipo
