hibernate SessionFactory的获取方法

Hibernate 4 已经将configuration的buildSessionFactory方法已经划线了，说明已经过时了。

Configuration configuration = new Configuration().configure();
SessionFactory sessionFactory = configuration.buildSessionFactory();

4.1之后的方法是：

ServiceRegistry serviceRegistry = null;

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

SessionFactory sessionFactory = configuration.buildSessionFactory(serviceRegistry);
