[resteasy-dev] SPI to add JAX-RS annotations dynamically

[Alessio Soldano]

Hi Christian,
I could not find something like what you mentioned, in RESTEasy. AFAICS,
the registry is meant for adding (registering) / removing resource
factories and getting resource invokers. Btw, I suspect it won't be safe to
alter a ResourceMethod metadata once it's been added to the registry. If
that's really the case, you should probably kick in before a resource
(factory) is actually added.
Have you looked at the resteasy-cdi integration btw? I'm wondering if your
scenario could be covered by extending the resteasy-cdi integration,
considering you said that MVC controllers are CDI-based JAX-RS resources.
Cheers
Alessio
