hibernate Criteria中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 

Java代码  

1. Restrictions.disjunction();  

用来组合一组逻辑与【and】条件的方法 

Java代码 

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);
        }
