Hibernate - ServiceRegistryBuilder

Question

I\'m just trying to learn Hibernate (version 4 final) but I have a problem when trying to create the session factory. Here is some code related to the problem:

hi

Answer 1

The methods buildSessionFactory and ServiceRegistryBuilder in Hibernate 4.3.4 are deprecated.

The right code is here.

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;


.....

    Configuration conf = new Configuration()
              .configure();


    ServiceRegistry sr = new StandardServiceRegistryBuilder().applySettings(conf.getProperties()).build();


    SessionFactory sf = conf.buildSessionFactory(sr);

    Session session = sf.openSession();

    session.beginTransaction();


    YourDominClass ydc = new YourDominClass();

    ydc.setSomething("abcdefg");

    session.save(ydc);

    session.getTransaction().commit();

    session.close();

    sf.close();
            ........

Answer 2

As answered in hibernate 4.0.0. CR4: org.hibernate.internal.util.config.ConfigurationException with hibernate.cfg.xml, the new way of creating SessionFactories doesn't work yet. It will be ready in Hibernate 4.1.

Answer 3

Here is the deprecated method from Configuration that still works. It is doing a lot of hibernate specific setup that hibernate users wouldn't really want to do. Things like veryifying properties and copying them from one object to another. I have also been looking for a working example of Hibernate configuration for Hibernate 4 that does not use the deprecated buildSessionFactory() method and have been unable to find one so far. I believe that the intent is to deprecate Configuration entirely.

public SessionFactory buildSessionFactory() throws HibernateException {
    Environment.verifyProperties( properties );
    ConfigurationHelper.resolvePlaceHolders( properties );
    final ServiceRegistry serviceRegistry =  new ServiceRegistryBuilder()
            .applySettings( properties )
            .buildServiceRegistry();
    setSessionFactoryObserver(
            new SessionFactoryObserver() {
                @Override
                public void sessionFactoryCreated(SessionFactory factory) {
                }

                @Override
                public void sessionFactoryClosed(SessionFactory factory) {
                    ( (StandardServiceRegistryImpl) serviceRegistry ).destroy();
                }
            }
    );
    return buildSessionFactory( serviceRegistry );
}
