hibernate Criteria中多个or和and的用法 and ( or or)

/s筛选去除无效数据
/* detachedCriteria.add(
Restrictions.or(
Restrictions.like("chanpin", "冰箱", MatchMode.ANYWHERE),
Restrictions.or(
Restrictions.like("chanpin", "洗衣机", MatchMode.ANYWHERE),
Restrictions.or(
Restrictions.like("chanpin", "热水器", MatchMode.ANYWHERE),
Restrictions.like("chanpin", "空调", MatchMode.ANYWHERE))))
);
*/
Disjunction dis=Restrictions.disjunction();
dis.add(Restrictions.like("chanpin", "冰箱", MatchMode.ANYWHERE));
dis.add(Restrictions.like("chanpin", "洗衣机", MatchMode.ANYWHERE));
dis.add(Restrictions.like("chanpin", "热水器", MatchMode.ANYWHERE));
dis.add(Restrictions.like("chanpin", "空调", MatchMode.ANYWHERE));
detachedCriteria.add(dis);
//e筛选去除无效数据

用来组合一组逻辑或【or】条件的方法

Restrictions.disjunction();

用来组合一组逻辑与【and】条件的方法

Restrictions.conjunction();

实际中有sql如下: where transportType=1 and ((pol=1 and pod=2) or (pol=1 and pod=3) or (pol=1 and pod=4))

代码如下

Criteria criteria = getCriteria();

        if(transportType!=null)criteria.add(Restrictions.eq("transportType", transportType));

        if(polIdStr!=null && podIdStr!=null) {

            List<Integer> polIdList = ListUtil.stringToList(polIdStr);

            List<Integer> podIdList = ListUtil.stringToList(podIdStr);

            List<Criterion> CriterionList=new ArrayList<Criterion>();

            Disjunction dis = Restrictions.disjunction();//多个or可以拼蛸

            for(int polId:polIdList){

                for(int podId:podIdList){

                    Conjunction con=Restrictions.conjunction();//多个and拼接

                    con.add(Restrictions.eq("polId", polId));

                    con.add(Restrictions.eq("podId", podId));

                    dis.add(con);

                }

            }

            criteria.add(dis);

        }
