class level injection using custom annotation

[asookazian]

So this is a Seam 2 example that I'm wondering how 299/WB handles.

I use this boilerplate code a lot in my Seam components:

@In     
private EntityManager entityManager;
     
@Logger     
private Log log;

So in WB it would be:

@PersistenceContext EntityManager userDatabase;

@Current Logger log;

So my idea (or request) is to inject n instances simultaneously using a custom annotation.

something like this:

@InjectPCandLogger
public class foo{
...
}

Would this be implemented using a stereotype or is this a totally different idea/implementation (perhaps extending an abstract class)?

The purpose of this is to reduce the amount of boilerplate code that we must write for each Web Bean component or Seam component.  Would work well when there's only one datasource for a particular app.

Use a superclass for the em and logger? Or an interceptor/decorator? Seems like even more hardcoding to use a custom annotation (and figure out where to process it).

PS. @Current is now @Inject

[nickarls]

But yes, @InjectPCandLogger could be a stereotype which carries the interceptor

Good.  that's clearer now, I did not like @Current...
