Hibernate Criteria 多层次查询关联问题

[code="java"]
class House{
private string houseid;
private string housename;
}
class Shelf{
private string shelfid;
private House house;
}
class Position{
private string positionid;
private Shelf shelf;
}
class Warehouse{
private string warehouseid;
private Position position;
}
[/code]

只用QBC能不能这样类似的解决呢?
[quote]
Criteria criteria = BaseUtil.getCriteria(Warehouse.class);

criteria.add(Expression.eq("position.shelf.house.houseid", "111"));

[/quote]
[b]问题补充：[/b]

1. Criteria criteria = BaseUtil.getCriteria(Warehouse.class);
   
2. CriteriaUtil.addAlias((CriteriaImpl)criteria, "position", "position");
   
3. CriteriaUtil.addAlias((CriteriaImpl)criteria, "position.shelf", "shelf");
   
4. criteria.add(Expression.eq("shelf.house.houseid", "111"));
   

这个不要贴了 我看过了 觉得麻烦才问的

我就是用你说的麻烦的方法同的原理实现，无限级联部份属性查询，
但是真正调用时，我的并不麻烦，我的业务代码中是类似这样的：
[code="java"]
//查询用户的三个字段，第一和第二个属性不说了，第三个是所属组织的父组织的名字
String[] columns = {"id","name","org.parentOrg.name"};
//得到Criteria
Criteria criteria = BaseUtil.getCriteria(Warehouse.class,columns,alias);
//查询
dao.findByDetached(criteria);
[/code]

业务代码写成这样你不觉得麻烦吧，级联查询是在框架中封装的，我觉得麻烦点无所谓，反正不用你去写，有兴趣可以到我博客看看

[code="java"]
Criteria criteria = BaseUtil.getCriteria(Warehouse.class);

CriteriaUtil.addAlias((CriteriaImpl)criteria, "position", "position");

CriteriaUtil.addAlias((CriteriaImpl)criteria, "position.shelf", "shelf");

criteria.add(Expression.eq("shelf.house.houseid", "111"));

[/code]
