Mysql语句是:select * from Product as p order by p.addtime desc limit 6 

Hibernate的DAO类中的语句是：from Product as p order by p.addtime desc limit 6

在mybtis映射可以这样写：

	/**
	* @version 创建时间：2018年4月19日17:03:35
	* @introduction  主页查找最新的六条新闻
	*/
	@Select("select * from Makeup_news  where mdelete=0 order by pubdate desc limit 6 ")
	@Results(value={
			@Result(column="newsid",property="newsid"),
			@Result(column="content",property="content"),			
			@Result(one=@One(select="com.lnsf.warehouse.dao.Makeup_userDao.getOneUserByUserId"),column="userId",property="makeup_user"),	
			@Result(column="mdelete",property="mdelete"),
			@Result(column="picture",property="picture"),
			@Result(column="pointquantity",property="pointquantity"),
			@Result(column="pubdate",property="pubdate"),
			@Result(column="title",property="title"),
				
			@Result(one=@One(select="com.lnsf.warehouse.dao.Makeup_newstypeDao.getOneNewstypebyTypeId"),column="typeid",property="makeup_newstype")
			})
	public List<Makeup_news> getSixNewsDescLimitTime();
