My suggestions is to keep Dao clean from your business logic but yes all the database related logic and customization should write at DAO layer like all hibernate logic, Casting of result into your Classes etc.. (As you are using Hibernate) should be written in DAO.

And whole iteration, setting/getting, result customization, preparation, request improvement to work as parameter for hibernate query should be written at service layer.

One another layer Controller should work over service layer which will receive request and call respective service Method and provide generated response.
