Beans added via Extensions and Interceptors and Decorators

[David Blevins <da...@gmail.com>]

Looks as though we don't support Interceptors or Decorators for beans added via extension that are not subclasses of AbstractOwbBean.

ThirdpartyBeanImpl returns an inner class impl of Producer from getProducer.  Since it doesn't extend AbstractProducer it doesn't have the defineInterceptorStack method and we skip it at the time where we would resolve those.

Is there a reason we don't have the inner class in ThirdpartyBeanImpl extend AbstractProducer?

Yes, that was the case until CDI-2.0 ;)

In CDI 2.0 we sat together at the face2face meeting in Brno and as a team created the javax.enterprise.inject.spi.InterceptionFactory
This can be used in producerMethods to create a proxy. Simply have the InterceptionFactory as injection point in the producer method.

  public MyStuff createIt(InterceptionFactory<MyStuff> interceptionFactory) {
    MyStuff myStuff = new MyStuff(...);
    return interceptionFactory
        .configure()  <- this gives you an AnnotatedTypeConfigurator<MyStuff>
        .add(new SomeInterceptorAnnotation())
        .createInterceptedInstance(myStuff);
  }

The same can be done withIn Bean#create, but you have to get the InterceptionFactory from the BeanManager.

Imo that's one of the coolest new features of CDI-2.0!
And one of the reasony I'd love to further push the work on TomEE8 ;)

Hi Romain, David,

I remember that discussion in the EG and that outcome, too. The conclusion
was, that 3rd party beans have to define their own interceptor decorator
stack and create it in Bean#create

Cheers,
Arne

Hi David

IIRC 3rd party beans - including @Produces - dont support producers (in the
spec) since there are fully let to the user. This is why deltaspike has
this partialbean interceptor support.

ThirdpartyBeanImpl returns an inner class impl of Producer from
getProducer.  Since it doesn't extend AbstractProducer it doesn't have the
defineInterceptorStack method and we skip it at the time where we would
resolve those.

Is there a reason we don't have the inner class in ThirdpartyBeanImpl
extend AbstractProducer?
