hibernate in List查询条件 sum求和使用参考

    @Override
    public Integer getSumZongShuByidList(List<String> idList){
        Integer zongshu = 0;
        String hql="SELECT sum(zongshu) from Tab  where id in (:idList)";
        Query query=this.getSession().createQuery(hql);
        query.setParameterList("idList", idList);
        Long queryZongShu = (Long)query.uniqueResult();
        if(queryZongShu!=null){
            zongshu = Integer.parseInt(queryZongShu.toString());
        }
        return zongshu;
    }
