Hi Paul,
I've gone ahead and logged an enhancement issue.
I personally prefer the getInjectableInstance(Object resource) approach as it deferrs injection to Jersey and is more resistant to change.
Many thanks,
Duncan Eley

Hi Paul,
I've not looked in any great detail at the new component provider but I can't see how the AOP trick can be applied using it. The getInstance() method in the SPI by Marc gave access to a ResourceProviderContext. This allowed me to inject dependencies on the proxy's target object and then return the proxied object itself from getInstance(). The target object cannot be the object returned from getInstance().
Using the component provider, how can we do the DI on the target object? Or there there some other solution to this that I'm not aware of?
Ah! you are right, can you please log an issue so that i don't forget about this?
We may need another method on ComponentProvider e.g. Object getInjectableInstance(Object resource) that Jersey can call and perform injection on the returned instance. Or we have to provide a context as before.
Thanks,
Paul.
Many thanks,

Yes, you should be able to do the same AOP trick with the component
provider [1].

Very much agree. I would like to consider something like that for 0.7
(see my blog on the 0.6 release), my concern is Marc, Jakub and I are a
little maxed out so i was wondering if anyone would like to volunteer to
contribute Spring & Guice stuff to the Jersey distribution ?
Paul.
