@within not working Spring AOP [SPR-17285]

[spring-projects-issues]

sahil-ag opened SPR-17285 and commented

@within point-cut doesn't seem to be working when we extend a class and annotate the extended class.
This also doesn't seem to take into account the @inherited annotation

Sample project:
https://github.com/sahil-ag/Spring-AOP-Sample

Project works when we use @target but should also be working for @within

No further details from SPR-17285

Hi
Is there any update here?

Sorry, haven't had a chance, but I will take a look at the project you attached (thanks for that!) as soon as I can.

Ok, @within, like within, is about lexical scope and what is declared at compile/weave time. @target, like target, is about dynamic scope and what is happening at runtime.

For the 3 testcases:
If the pointcuts are
( A ): @within(SampleAnnotation) || @annotation(SampleAnnotation)
( B ): @target(SampleAnnotation) || @annotation(SampleAnnotation)

• testAnnotedMethod - Both A and B match because @annotation(SampleAnnotation) matches on the method in BaseMethod class.
• testAnnotatedBeanExtended - B matches, A does not match. The method getTestName() is declared in BaseClass and neither that method or that type is annotated, so if that is the static state 'as declared' and so neither of these pointcut components are true in A. Now B matches dynamically because the runtime type on which the getTestName() is being called is a BaseClassExtended which is annotated.
• testAnnotatedBean - Neither A nor B match. BaseClass nor getTestName() are annotated.

So I am saying it is working as designed. Does that help?

Correct me if I am wrong but shouldn't @within consider all the functions which are available to the class at compile time and based on how inheritance works, that function will hence be available in the lexical scope?

@annotation not working. I tried whole day to make it work. Is anyone has workaround it?
