Hibernate query for multiple items in a collection

Question

I have a data model that looks something like this:

public class Item {
    private List attributes;
    // other stuff
}

public class Item         


        

Answer 1

Could you use aliasing to do this?

Criteria itemCriteria = session.createCriteria(Item.class);
itemCriteria.createAlias("itemAttributes", "ia1")
            .createAlias("itemAttributes", "ia2")
            .add(Restrictions.eq("ia1.name", "foo1"))
            .add(Restrictions.eq("ia1.attributeValue", "bar1")))
            .add(Restrictions.eq("ia2.name", "foo2"))
            .add(Restrictions.eq("ia2.attributeValue", "bar2")))

Not sure how hibernate handles joining on the same property twice explicitly like that, maybe worth trying?
