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

1. /s筛选去除无效数据
2. /*      detachedCriteria.add(
3. Restrictions.or(
4. Restrictions.like("chanpin", "冰箱", MatchMode.ANYWHERE),
5. Restrictions.or(
6. Restrictions.like("chanpin", "洗衣机", MatchMode.ANYWHERE),
7. Restrictions.or(
8. Restrictions.like("chanpin", "热水器", MatchMode.ANYWHERE),
9. Restrictions.like("chanpin", "空调", MatchMode.ANYWHERE))))
10. );
11. */
12. Disjunction dis=Restrictions.disjunction();
13. dis.add(Restrictions.like("chanpin", "冰箱", MatchMode.ANYWHERE));
14. dis.add(Restrictions.like("chanpin", "洗衣机", MatchMode.ANYWHERE));
15. dis.add(Restrictions.like("chanpin", "热水器", MatchMode.ANYWHERE));
16. dis.add(Restrictions.like("chanpin", "空调", MatchMode.ANYWHERE));
17. detachedCriteria.add(dis);
18. //e筛选去除无效数据

用来组合一组逻辑或【or】条件的方法

1. Restrictions.disjunction();

用来组合一组逻辑与【and】条件的方法

1. 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);
        }
