hibernate3.X构造SessionFactory方法

//读取hibernate.cfg.xml文件  Configuration cfg = new Configuration().configure();        //建立SessionFactory  SessionFactory factory = cfg.buildSessionFactory();

 在hibernate4.3中函数buildSessionFactory()已经作废，以下是新的构造方法

private static ServiceRegistry serviceRegistry = null;    private static Configuration cfg = null;    private static SessionFactory sessionFactory = null;        cfg = new Configuration().configure();        serviceRegistry = new StandardServiceRegistryBuilder().applySettings(cfg.getProperties()).build();        sessionFactory = cfg.buildSessionFactory(serviceRegistry);        //取得session          Session session = null;        //开启session          session = sessionFactory.openSession();
