Imagine the path:



That means that entity1 has an object entity2.
Entity2 has an object entity3
(so on...)
entity5 has attribute "attribute".

I want to create an criteria to search for that "attribute" on "entity5". How should my criteria be:



or this only this works? :


PS: can I create an alias for the root entity?


I´m asking this, because I´m trying to create a generic filter using Criteria.
Thanks all!

entity1.entity2.entity3.entity4.entity5.attribute;

In this case i believe that entity1 has a reference of entity2 which intern has a reference of entity3....and entity5 has an attribute.
And You want to fetch value where the constraint is attribute in entity5.
What value you have with you is the entityObject1 and with this you gonna fetch the value.

What you can do here is.

While creating instance of your helper class, say like Query is your helper class. so


Query query2 - new Query(entity2.class);
query.addCriteria("query1", entity1Object);

Query query3 - new Query(entity3.class);
query.addCriteria(query2);

Query query4 - new Query(entity4.class);
query.addCriteria(query2);

Query query5 - new Query(entity5.class);
query5.addCriteria(query4);
query5.addCriteria("attribute", attribute);

Now pass this query5 to the hibernate using :

getDefaultDao().findUsing(query5)

Hope this will help you.
