测试一
public void testSave1(){
Session session = null;
Transaction tx = null;
try{
session = HibernateUtils.getSession();
tx = session.beginTransaction();
User user = new User();
user.setName("李四");
user.setPassword("123");

user.setExpireTime(new Date());
session.save(user);
tx.commit();
}catch (Exception e) {
tx.rollback();
}finally{
HibernateUtils.closeSession(session);
}
}
执行：
Hibernate: insert into User (name, password, createTime, expireTime, id) values (?, ?, ?, ?, ?)
