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

Why wouldn't the following work?

return getSession().createCriteria(Item.class)
    .createAlias("itemAttributes", "ia")
    .add(Restrictions.or()
        .add(Restrictions.conjunction()
            .add(Restrictions.eq("ia.name", "foo1"))
            .add(Restrictions.eq("ia.attributeValue", "bar1")))
        .add(Restrictions.conjunction()
            .add(Restrictions.eq("ia.name", "foo2"))
            .add(Restrictions.eq("ia.attributeValue", "bar2"))))
    .list();

That would be (name=foo1 && attributeValue=bar1) OR (name=foo2 && attributeValue=bar2)
