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 (?, ?, ?, ?)
