Hibernate-4.3.6 创建sessionFactory的方式

在Hibernate4.3中ServiceRegistryBuilder被标记为过时，创建sessionFactory要用以下方式：

private static SessionFactory buildSessionFactory() {Configuration cfg = new Configuration();cfg.configure();serviceRegistry =  new StandardServiceRegistryBuilder().applySettings(cfg.getProperties()).build();SessionFactory sessionFactory = cfg.buildSessionFactory(serviceRegistry);return sessionFactory;}
