Boa noite
Estou iniciando um novo projeto com VRaptor.
Ja trabalhei outros projetos, ams agora estou encontrando um erro logo no inicio da estrutura. Queria saber se algo mudou nas ultimas versoes (ja trabalhei com VRaptor 3 antes)
Tenho um DaoFactory
@Component
public class DaoFactory {
protected Session session;
public DaoFactory (Session session){
this.session = session;
}
public Session getSession() {
return session;
}
public Dao<Produto> getProdutoDao () {
return new Dao<Produto>(this.session, Produto.class);
}
}
Se seguir a apostila da Caelum, e criar as classes ComponentFactory para SessionFactory e para Session, funciona:
import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.AnnotationConfiguration;
import br.com.caelum.vraptor.ioc.ApplicationScoped;
import br.com.caelum.vraptor.ioc.Component;
import br.com.caelum.vraptor.ioc.ComponentFactory;
@SuppressWarnings("deprecation")
@Component
@ApplicationScoped
public class FabricaSessionFactory implements ComponentFactory<SessionFactory>{
private SessionFactory factory;
@PostConstruct
public void abre(){
AnnotationConfiguration conf = new AnnotationConfiguration();
conf.configure();
this.factory = conf.buildSessionFactory();
}
public SessionFactory getInstance() {
return this.factory;
}
@PreDestroy
public void fecha(){
this.factory.close();
}
}
import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import br.com.caelum.vraptor.ioc.Component;
import br.com.caelum.vraptor.ioc.ComponentFactory;
@Component
public class FabricaSession implements ComponentFactory<Session> {
private SessionFactory factory;
private Session session;
private Transaction tx;
public FabricaSession (SessionFactory factory){
this.factory = factory;
}
@PostConstruct
public void abre(){
this.session = factory.openSession();
tx = session.beginTransaction();
}
public Session getInstance() {
return this.session;
}
@PreDestroy
public void fecha(){
tx.commit();
this.session.close();
}
}
Contudo, tenho receio de estar tratando mal algum recurso que possa impactar no desempenho de minha aplicação, então tentei usar da maneira que já fiz em outros projetos que trabalhei com VRaptor 3, colocando no meu web.xml:
<context-param>
<param-name>br.com.caelum.vraptor.provider</param-name>
<param-value>br.com.caelum.vraptor.util.hibernate.HibernateCustomProvider</param-value>
</context-param>
E deixando o VRaptor e o Hibernate gerenciar as SessionFactory e as Session.
Mas quando tiro as duas classes acima, ComponenteFactory, e coloco isso no web.xml, da o seguinte erro:

Alguém sabe me dizer onde estou errando? com esse trecho do web.xml, o VRaptor e Hibernate não deveria disponibilizar a Session apra o meu DaoFactory?
Aproveito e pergunto se é melhor prática utilizar o provider do VRaptor/Hibernate ou usar as classes ComponentFactory, como na apostila e como fiz funcionar.
Desde já agradeço qualuqer ajuda.
