休眠条件返回集

Question

I Have a class which contains a Set of objects. Using Hibernate Criteria, how can I return that Set of objects, as opposed to the objects of the class on which the query is being called?

In standard HQL, I'm using the following : select o.routes from Operator o where o.name = :diamond , where routes is the set of objects I wish to retrieve.

I think you are looking for something like this How to add Distinct in Hibernate Criteria where in you are setting the projection to a specific object. you can also convert it to the class of that object.
