DetachedCriteria多条件查询or，disjunction

[java] view
plaincopy





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)】：

[java] view
plaincopy





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();】：

[java] view
plaincopy





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);

}
