Re: [cdi-dev] @New and producer methods/fields
Section 3.12 states "For each managed bean, and for each session bean, a second bean
exists which:"
So, there are no @New beans for producers.
What is the use case you are trying to address?

Hi folks!
We recently talked about ways to properly destroy beans which got created via Instance or
@New.
I just realized that only having
@Inject @New MyClass dings;
might not be enough.
Imagine you have 2 producer methods which create EntityManagers
public class EntityManagerProducer {
@Produces @RequestScoped @UserDb
public void createUserDbEm() {
return entityManagerFactory.createEntityManager("userdb");
}
@Produces @RequestScoped @AdminDb
public void createAdminDbEm() {
return entityManagerFactory.createEntityManager("admindb");
}
}
If I need a 'temporarily self managed' userdb EntityManager, I cannot just
type
@Inject @New @UserDb EntityManager userDbEm;
because according to the spec there is only 1 Bean with exactly @New (and none with
additional @UserDb)
The @New is basically useless for producer methods, isn't?
Do we like to address this somehow?
LieGrie,
