HQL实现新闻上一篇下一篇

要实现新闻的上一篇下一篇功能，关键是HQL语句

上一篇：HQL="from News d where d.id<? order by id desc";

下一篇：HQL="from News d where d.id>? order by id asc ";

daoImpl实现的方法：

public News nextPage(News news){
		try{
			String queryString="from News d where d.id<? order by id desc";
			Query queryObject=getSession().createQuery(queryString);
			queryObject.setLong(0,news.getId());
			queryObject.setFirstResult(0);
			queryObject.setMaxResults(1);<pre name="code" class="java">public News nextPage(News news) {
		try {
			String queryString = "from News d where d.id>? order by id asc";
			Query queryObject = getSession().createQuery(queryString);
			queryObject.setLong(0,news.getId());
			queryObject.setFirstResult(0);
			queryObject.setMaxResults(1);
			return (News)queryObject.list().get(0);
		} catch (RuntimeException re) {

			throw re;
		}
		
	}
