John D. Ament commented on DELTASPIKE-940:
------------------------------------------
While we shouldn't remove the old behavior pre-DS 2.0, it would be good to
provide similar capabilities in both.
As a result, I think it makes sense to include qualifier in the look up while
still allowing class based resolution.
> @Transactional and @EntityManagerConfig each use a different method to
> resolve EntityManagers

>
> When an application uses multiple {{EntityManager}}'s, there must be a way to
> specify which one(s) should be used. Currently, {{@Transactional}} and
> {{@EntityManagerConfig}} use different approaches:
> - {{@Transactional}} can take one or more qualifiers directly in its
> {{qualifier()}} member ({{@Transactional(qualifier = MyDB.class)}})
> - While {{@EntityManagerConfig}} must define an {{EntityManagerResolver}}
> ({{@EntityManagerConfig(entityManagerResolver =
> MyDBEntityManagerResolver.class}})
> I think both should be unified and use a single way to specify which
> {{EntityManager}} to use. IMHO, the {{@Transactional}} way of doing looks
> better and should be applied to {{@EntityManagerConfig}}.
