      @Nullable T doInHibernate(Session session) throws HibernateException
      Gets called by HibernateTemplate.execute with an active Hibernate Session. Does not need to care about activating or closing the Session, or handling transactions.

      Allows for returning a result object created within the callback, i.e. a domain object or a collection of domain objects. A thrown custom RuntimeException is treated as an application exception: It gets propagated to the caller of the template.

      Parameters:
      session - active Hibernate session
      Returns:
      a result object, or null if none
      Throws:
      HibernateException - if thrown by the Hibernate API
