All Implemented Interfaces:

UniversalORMDAO, org.springframework.beans.factory.InitializingBean

public class UniversalHibernateDAOImpl
extends org.springframework.orm.hibernate3.support.HibernateDaoSupport
implements UniversalORMDAO

This class serves as the a class that can CRUD any object witout any Spring configuration. The only downside is it does require casting from Object to the object class.
