关于Hibernate底层的查询处理（忽略大小写，模糊匹配，自动加载属性）

问题描述：Hibernate下做模糊匹配不区分大小写的时候，控制打印出来的脚本出现两个coornateName，明明我只传了一个，为什么会有两个？

①模糊匹配 like("属性",条件)

②忽略大小写 like("属性",条件).ignoreCase()

原因：HibrenateUtils.createDetachedCriteria(class,true)
会自动加载属性，也就是说只要action接收了属性对应的值，查询的时候，就会自动给该值做匹配（=）

原始脚本：

select
this_.id as id24_0_,
this_.axisId as axisId24_0_,
this_.isLock as isLock24_0_,
this_.addDate as addDate24_0_,
this_.coordinateName as coordina5_24_0_,
this_.PROCESSID as PROCESSID24_0_,
this_.parentId as parentId24_0_,
this_.coordinateValue as coordina8_24_0_,
this_.isValid as isValid24_0_,
this_.adduser as adduser24_0_
from
t_coordinate this_
where this_.coornaditeName = ? <pre name="code" class="sql"><span style="white-space:pre">	</span>and lower(this_.coordinateName) like ?

and this_.axisId=? order by this_.addDate desc

然后把HibrenateUtils.createDetachedCriteria(class,true)
换成DetachedCriteria.forClass(TCoordinate.class);

select
this_.id as id24_0_,
this_.axisId as axisId24_0_,
this_.isLock as isLock24_0_,
this_.addDate as addDate24_0_,
this_.coordinateName as coordina5_24_0_,
this_.PROCESSID as PROCESSID24_0_,
this_.parentId as parentId24_0_,
this_.coordinateValue as coordina8_24_0_,
this_.isValid as isValid24_0_,
this_.adduser as adduser24_0_
from
t_coordinate this_
where
this_.axisId=?
and lower(this_.coordinateName) like ?
order by
this_.addDate desc

完整的java代码：

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;
}

模糊匹配，忽略大小写的关键代码：

dc.add(Restrictions.like("coordinateName", conditions.getCoordinateName(),MatchMode.ANYWHERE).ignoreCase());
