Re: [Springframework-developer] MethodMatchers and Introductions

[Rod J. <rod...@in...>]

The new IntroductionAdvice is the only way to add an introduction. This has
only a ClassFilter. It doesn't make sense for an introduction to be
conditional by method: it's set up when the proxy is created.

If an introduction interceptor wanted to let a particular method call
through even on one of its introduced interfaces (an unusual scenario that
you might use only if you wanted to mask some methods of a target that also
implemented the introduced interface) it could override invoke() and call
proceed() on those methods.

Btw, the DelegatingIntroductionInterceptor could probably be used to achieve
what you wanted regarding the introduction advice implementing the interface
(ie an abstract IntroductionAdvice that subclasses
DelegatingIntroductionInterceptor and leaves subclasses to implement a
single target method). I think this can be handled by subclassing, rather
than in the core framework.

Regards,
Rod
