import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;

public class HibernateUtil {
private static SessionFactory sessionFactory = buildSessionFactory();

private static SessionFactory buildSessionFactory()
{
try
{
if (sessionFactory == null)
{
Configuration configuration = new Configuration().configure(HibernateUtil.class.getResource("/hibernate.cfg.xml"));
StandardServiceRegistryBuilder serviceRegistryBuilder = new StandardServiceRegistryBuilder();
serviceRegistryBuilder.applySettings(configuration.getProperties());
ServiceRegistry serviceRegistry = serviceRegistryBuilder.build();
sessionFactory = configuration.buildSessionFactory(serviceRegistry);
}
return sessionFactory;
} catch (Throwable ex)
{
System.err.println("Erro criacao session Facotry :" + ex);
