结果演示：

html:

java:

public HibernateTableQueryState generateQueryState(boolean isRequery) {DocChannelDocmentDAO dao = getDocChannelDocmentDAO();HibernateTableQueryState queryState = new HibernateTableQueryState();queryState.setIsRequery(isRequery);// 设定DAOqueryState.setHibernateDAO(dao);String hql = dao.getHQL_All()+ " where docChannelDocmentHBM.docStatus='已发布' " +"and docChannelDocmentHBM.docChannel.docChannelId in ("+ getChannelIds(getDocChannelId())+ ") order by docChannelDocmentHBM.isTop desc,docChannelDocmentHBM.docment.createTime desc ";// 设定查询语句queryState.setHql(hql);// 设定查询结果的列表个数queryState.setRowCountHql(dao.getHQL_RowCount()+ " where docChannelDocmentHBM.docStatus='已发布' and docChannelDocmentHBM.docChannel.docChannelId in ("+ getChannelIds(getDocChannelId())+ ") order by docChannelDocmentHBM.isTop desc,docChannelDocmentHBM.docment.createTime desc");queryState.setHqlBuilder(getHqlBuilder());queryState.setHibernateDAO(getDocChannelDocmentDAO());return queryState;}
