hibernate4 获取SessionFactory

//读取hibernate.cfg.xml文件
Configuration cfg = new Configuration().configure();
//      建立SessionFactory
//buildSessionFactory 过时
//      SessionFactory factory = cfg.buildSessionFactory();
//ServiceRegistryBuilder 过时
//      ServiceRegistry serviceRegistry = new ServiceRegistryBuilder().applySettings(cfg.getProperties()).buildServiceRegistry();
//      SessionFactory factory = cfg.buildSessionFactory(serviceRegistry);
//4.X
StandardServiceRegistry standardServiceRegistry = new StandardServiceRegistryBuilder().applySettings(cfg.getProperties()).build();
SessionFactory factory = cfg.buildSessionFactory(standardServiceRegistry);
