一样的问题， 已解决。

 hibernate换到最新的5.2.1

然后代码这样写

public class StudentTest {

private Configuration config ;

private SessionFactory sessionFactory;

private Session session;

private Transaction transaction;

@Before

public void init(){

config = new Configuration().configure();

sessionFactory = config.buildSessionFactory();

session = sessionFactory.openSession();

transaction = session.beginTransaction();

}

@Test

public void testSave(){

Student s = new Student(18, 16, "Lucy", new Date());

session.save(s);

}

@After

public void destory(){

transaction.commit();

session.close();

sessionFactory.close();

}

}
