Emily Jiang commented on CDI-420:
Martin, for implementing of Include, the scan process has to be changed. I do agree that your exclusion involves less changes.
I think Martin's approach can do a finer-grain exclusion, on a package basis. e.g. If I have a jar containing some third party classes, org.apache.* plus in-house package com.abc.blah. I can exclude the classes without bean defining annotations from the package org.apache.* while I can include all classes from the package com.abc.blah.
> 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...
