Hibernate查询时如何接收多个字段值

最近做项目碰到一个Hibernate的多字段查询时，如何接收的问题，如接收多个查询函数的结果。

JAVA：
Java代码  

//**************************
        hql="select a.productId,a.productName,a.productPrice,a.validDate,(select nvl(sum(b.orderNum-b.refundNum),0) from Order b where b.orderStatus not in (1,7,8) and b.product.productId=a.productId) from  Product a where a.status in (1,3)";

        if(goodCode!=null&&!"".equals(goodCode)){
            hql +=" and a.productId=:goodCode";
        }
        if(goodName!=null&&!"".equals(goodName)){
            hql +=" and a.productName like :goodName";
        }
        hql+=" order by a.status asc,a.productId desc";
        query = sessionFactory.getCurrentSession().createQuery(hql);
        if(goodCode!=null&&!"".equals(goodCode)){
            query.setString("goodCode", goodCode);
        }
        if(goodName!=null&&!"".equals(goodName)){
            query.setParameter("goodName", "%"+goodName+"%");
        }


        int spag = (pag - 1) * pagnum;
        query.setFirstResult(spag);
        query.setMaxResults(pagnum);
        List results = query.list();
        List<Map> lm = new ArrayList();
        for (Iterator iterator = results.iterator(); iterator.hasNext(); ) {
            Object[] rows = (Object[]) iterator.next();
            Map map = new HashMap();
            map.put("productId", (Integer) rows[0]);
            map.put("productName", (String) rows[1]);
            map.put("productPrice", (Double) rows[2]);
            map.put("validDate", CommonUtil.fmtDate((Date) rows[3]));
            map.put("productNum", (Long) rows[4]);
            lm.add(map);

        }

在页面上用struts2标签：
