hibernate配置

今天在學習Hibernate、在配置的過程報了一個以下的錯誤、

　 org.hibernate.HibernateException: Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set

仔細檢查了一下、也沒發現有什麼錯、配置也都是參照官方文檔寫的、

後來在網上查了一下、說是Hibernate  4.X以後廢棄了原來的buildSessionFactory方法、改成最新的後、就能夠正常運行了、代碼以下、

錯誤的代碼:

                Familly f = new Familly();
		f.setFamilyid(1);
		f.setSex("1");
		f.setCifname("楊");
		f.setRelname("軍");
		
		Configuration cfg = new Configuration();
		SessionFactory sessionFactory = cfg.configure().buildSessionFactory(new StandardServiceRegistryBuilder().build());
		Session session = sessionFactory.openSession();
		session.beginTransaction();
		session.save(f);
		session.getTransaction().commit();
		session.close();
		sessionFactory.close();

　　

修改後的正確代碼:

                Familly f = new Familly();
		f.setFamilyid(1);
		f.setSex("1");
		f.setCifname("楊");
		f.setRelname("軍");
		
		Configuration cfg = new Configuration().configure();
		StandardServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder()
		                    .applySettings(cfg.getProperties()).build();
		SessionFactory sessionFactory = cfg.buildSessionFactory(serviceRegistry);
		
		/* 廢棄一下
		Configuration cfg = new Configuration();
		SessionFactory sessionFactory = cfg.configure().buildSessionFactory(new StandardServiceRegistryBuilder().build());
		*/
		
		Session session = sessionFactory.openSession();
		session.beginTransaction();
		session.save(f);
		session.getTransaction().commit();
		session.close();
		sessionFactory.close();

打印生成的SQL以下：

Hibernate: insert into CR_FAMILY (cifname, relname, sex, familyid) values (?, ?, ?, ?)
