Hibernate4的buildSessionFactory过时

今天想用Hibernate4时候发现原先的buildSessionFactory已经过时，百度谷歌API得之解决方案

原先是：

static {Configuration cfg = new Configuration();cfg.configure();sessionFactory = cfg.buildSessionFactory();}

改为：

static {Configuration cfg = new Configuration();cfg.configure();ServiceRegistry sr = new ServiceRegistryBuilder().applySettings(cfg.getProperties()).buildServiceRegistry();sessionFactory = cfg.buildSessionFactory(sr);}
