休眠4是否弃用了buildSessionFactory（）？

Question

当我将Hibernate的版本从3.6.8.final更新到4.0.0.final时，buildSessionFactory()在此行中收到有关过时方法的警告：private static final SessionFactory sessionFactory =         new Configuration().configure().buildSessionFactory();javadoc建议使用另一种方法buildSessionFactory(ServiceRegistry serviceRegistry)但是在文档中我发现不推荐使用的变体:(您能帮我解决这个小小的误会吗？

要么

public class Hbutil {

    private static SessionFactory sessionFactory;

    private static ServiceRegistry serviceRegistry;

    private static SessionFactory configureSessionFactory() throws HibernateException {

        Configuration configuration = new Configuration();

        configuration.configure();

        serviceRegistry = new ServiceRegistryBuilder().applySettings(configuration.getProperties()).buildServiceRegistry();        

        sessionFactory = configuration.buildSessionFactory(serviceRegistry);

        return sessionFactory;

    }

    public static SessionFactory getSessionFactory() {

        return configureSessionFactory();

    }

}
