hibernate配置

今天在学习Hibernate、在配置的过程报了一个如下的错误、

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

仔细检查了一下、也没发现有什么错、配置也都是参照官方文档写的、

后来在网上查了一下、说是Hibernate  4.X之后废弃了原来的buildSessionFactory方法、改为最新的后、就可以正常运行了、代码如下、

错误的代码:

                Familly f = new Familly();		f.setFamilyid(1);		f.setSex("1");		f.setCifname("杨");		f.setRelname("军");				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();

  

修改后的正确代码:

                Familly f = new Familly();		f.setFamilyid(1);		f.setSex("1");		f.setCifname("杨");		f.setRelname("军");				Configuration cfg = new Configuration().configure();		StandardServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder()		                    .applySettings(cfg.getProperties()).build();		SessionFactory sessionFactory = cfg.buildSessionFactory(serviceRegistry);				/* 废弃一下		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如下:

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