如何创建日期具体的查询条件处于休眠

Question

如何创建休眠标准以下查询：

select * from xmppserveripinfo where update_dt > (select DATE_SUB(NOW(),INTERVAL 1 MINUTE)) 

Answer 1

这个例子演示了它是如何工作的：

public List<XmppServerIpInfo > find(final int intervalInMinutes) { 
    return getHibernateTemplate().execute(new HibernateCallback<List<XmppServerIpInfo>>() { 

     public List<XmppServerIpInfo> doInHibernate(Session session) throws HibernateException, SQLException { 
      Criteria crit = session.createCriteria(XmppServerIpInfo.class); 
      Calendar cal = Calendar.getInstance(); 
      cal.add(Calendar.MINUTE, -intervalInMinutes); 
      crit.add(Restrictions.ge("updateTime", cal.getTime())); 
      crit.addOrder(Order.asc("updateTime")); 
      return crit.list(); 
     } 
    }); 
}
