Re: [Springframework-developer] InvokerInterceptor --> ??

I'd really need to see the code (maybe send it to me directly). I'm not
quite sure what this code is trying to do, but I'm almost positive there's a
better way :-)

It looks as though it's trying to invent its own pointcut model, instead of
using the framework's. Is it putting custom behaviour in the
InvokerInterceptor?

The replacement would be to set the target to the target object (you don't
normally need to use a TargetSource unless you want to do something fancy,
so this is just standard framework usage) and put the interception behaviour
in an interceptor that's distinct from the invocation of the target.

If some invocations need to go to an object other than the ultimate target,
any interceptor can do that. It just returns the result of reflective method
invocation on _its_ target, rather than invoking proceed().

Regards,
Rod
