DetachedCriteria多条件查询or，disjunction

public Page getCoordByPage(Page queryHandler, TCoordinate conditions) {
        DetachedCriteria dc = DetachedCriteria.forClass(TCoordinate.class);
        if (conditions.getTAxis() != null) {
            dc.add(Restrictions.eq("TAxis", conditions.getTAxis()));
        }

        if(conditions.getCoordinateName()!=null){
            dc.add(Restrictions.like("coordinateName", conditions.getCoordinateName(),MatchMode.ANYWHERE).ignoreCase());
        }

        if(conditions.getParentCoordinate().getId()!=null){
            dc.add(Restrictions.eq("parentCoordinate.id", conditions.getParentCoordinate().getId()));
        }

        dc.addOrder(Order.desc("addDate"));
        Page page = this.coordinateDao.getPageByCriteria(queryHandler, dc);
        return page;
    }

两个条件之间or的用法【Restrictions.or(lhs, rhs)】：

dc.add(Restrictions.or(Restrictions.like("country", comm.getCountry(),MatchMode.ANYWHERE).ignoreCase(),
                    Restrictions.like("pinyin", comm.getCountry(),MatchMode.ANYWHERE).ignoreCase()));

超过两个，比如三个条件之间的or【Disjunction disjunction = Restrictions.disjunction();】：

if(!ValidateUtils.isEmpty(comm.getCountry())){
            Disjunction disjunction = Restrictions.disjunction();

            disjunction.add(Restrictions.like("country", comm.getCountry(),MatchMode.ANYWHERE).ignoreCase());
            disjunction.add(Restrictions.like("pinyin", comm.getCountry(),MatchMode.ANYWHERE).ignoreCase());
            disjunction.add(Restrictions.like("jianpin", comm.getCountry(),MatchMode.ANYWHERE).ignoreCase());

            dc.add(disjunction);
        }

瞬即涨姿势！
