Olá pessoal, minha dúvida é parecida com a desse tópico, porém não consegui a solução por ele.
http://www.guj.com.br/java/200907-vraptor----duvidas-no-fj-28
Comecei a ler a apostila FJ-28 mas empaquei num erro aqui na hora de criar o ProdutosController.
Eu sou iniciante na parte de hibernate e no conceito de injeção de depêndencias, porém penso que o erro está relacionado ao hibernate.
Estou usando o hibernate.properties, ainda não aprendi a mexer no hibernate com xml.
Aqui está o stacktrace:

Aqui os codigos das classes onde eu creio que o problema esteja:
Controller:
package br.com.caelum.goodbuy.controller;
import java.util.List;
import br.com.caelum.goodbuy.dao.ProdutoDao;
import br.com.caelum.goodbuy.modelo.Produto;
import br.com.caelum.vraptor.Resource;
<a class="mention" href="/u/resource">@Resource</a>
public class ProdutosController {
private final ProdutoDao dao;
public ProdutosController(ProdutoDao dao) {
this.dao = dao;
}
public List<Produto> lista(){
return dao.listaTudo();
}
}
Dao:
package br.com.caelum.goodbuy.dao;
import java.util.List;
import org.hibernate.Session;
import br.com.caelum.goodbuy.modelo.Produto;
import br.com.caelum.vraptor.ioc.Component;
@Component
public class ProdutoDao {
private Session session;
public ProdutoDao(Session session) {
this.session = session;
}
public List<Produto> listaTudo() {
return this.session.createCriteria(Produto.class).list();
}
}
HibernateUtil:
package br.com.caelum.goodbuy.hibernate;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.AnnotationConfiguration;
import br.com.caelum.goodbuy.modelo.Produto;
public class HibernateUtil {
private static SessionFactory factory;
static {
AnnotationConfiguration cfg = new AnnotationConfiguration();
cfg.addAnnotatedClass(Produto.class);
factory = cfg.buildSessionFactory();
}
public Session getSession() {
return factory.openSession();
}
}
