Configuration configuration = new Configuration().configure();

//以下这两句就是4.3的新用法
StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());

StandardServiceRegistryImpl registry = (StandardServiceRegistryImpl) builder.build();

SessionFactory sessionFactory = configuration.buildSessionFactory(registry);

Session session = sessionFactory.openSession();

Transaction tx = session.beginTransaction();
