DetachedCriteria多條件查詢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; }
兩個條件之間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()));
超過兩個,比如三個條件之間的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); }
瞬即漲姿勢!
