Emily Jiang commented on CDI-420:
Thank you Matej for the explanation! Since Martin's snippet does not mention bean-discovery-mode, I thought it was the default one, "annotated". Hence the confusion.
If the proposal is to add exclusion in the mode of bean-discovery-mode="all", it seems to introduce a half veto, opting in for Type Discovery but not Bean Discovery. I think this should work and involves less change. I think if we directly expand the section 12.4.2. Exclude filters, we might be able to explain well.
> add a bean-discovery-mode 'scoped'
> Key: CDI-420
> URL: https://issues.jboss.org/browse/CDI-420
> Project: CDI Specification Issues
> Issue Type: Bug
> Components: Packaging and Deployment
> Affects Versions: TBD
> Reporter: Mark Struberg
> Fix For: 2.0 (discussion)
> This is for some future CDI release.
> We currently only have 3 bean-discovery-modes
> * none
> * all
> * annotated
> The spec also currently says that ProcessAnnotatedType will only get fired (12.4) for
> • each Java class, interface or enum deployed in an explicit bean archive, and
> • each Java class with a bean defining annotation in an implicit bean archive.
> • each session bean
> Which means that we do not get the ProcessAnnotatedType (PAT) event for any class in an 'annotated' or 'implicit' BDA which does _not_ have a bean defining annotation.
> It might be useful to fire the ProcessAnnotatedType for all classes, but do not pick them up as Beans if they (after PAT) do not have a valid scope. Effectively doing the processing but not make them @Dependent automatically if there is no scope annotation at the end of the PAT processing.
> I'm not yet 100% sure how important this distinction is in practice. Just writing this up to not forget about the idea...
