[Hibernate] Hibernate 4 에서의 getSessionFactory

Hibernate 4.0 메뉴얼상의 HibernateUtil 
-------------------------------------------------------------------------
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
/**
 * http://docs.jboss.org/hibernate/core/4.0/manual/en-US/html_single/
 */
public class HibernateUtil {
    private static final SessionFactory sessionFactory = buildSessionFactory();
    private static SessionFactory buildSessionFactory() {
        try {
            // Create the SessionFactory from hibernate.cfg.xml
            return new Configuration().configure().buildSessionFactory();
        }
        catch (Throwable ex) {
            // Make sure you log the exception, as it might be swallowed
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }
    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }
}
-------------------------------------------------------------------------
하지만 buildSessionFactory() 가 deprecation 된 상태이다
Deprecated. Use buildSessionFactory(ServiceRegistry) instead
라고나와있다
그래서 새로운 소스로 대체하였다.

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