Mark Struberg updated DELTASPIKE-315:
-------------------------------------
Description:
I found myself using the following pattern quite often in projects in the last
time. I have a @Qualifier UnitName(value) and a producer for a @Dependent
EntityManagerFactory for it. The configuration is mostly provided via the
persistenceProperties Map in
EntityManagerFactory#createEntityManagerFactory(unitname,
persistenceProperties);
We can further tweak the config lookup path and define a route which makes the
most sense.
This can be used to create the EntityManager producer very easily.
@ApplicationScoped
public class MyEntityManagerProducer {
private @Inject @UnitName("orderUnit") EntityManagerFactory emf;
@Produces @RequestScoped
public EntityManager createEm() {
return emf.createEntityManager();
}
.. + disposer
}
Please note that the EMF producer doens't clash with anything else as it only
produces EMFs with the Qualifier @UnitName!
