How Define PointCut for annotation on Interface ?

[och]

Hi,

I try to run an aspect when the method of class implementation is call if the interface of this class have an annotation...
With an example it's easier:

I have the interface with on annotation @Cacheable:

public interface AccountService {	
		
	@Cacheable
	public List<AccountDTO> getAccounts();	
}

And I have also an implementation of this interface

@Service
public class AccountServiceImpl implements AccountService{

	public List<AccountDTO> getAccounts() {
	...
	}
}

And also an Advice :

@Component
@Aspect
public class MyAdvice {
		
	@Pointcut("@within(Cacheable) || @Annotation(Cacheable)) 
	public static void addCachePointcut(){};
	
	@Around("addControlPointcut()")	
	public Object addCache(ProceedingJoinPoint point) throws Throwable{
	  ...	
	}

This code works fine if the annotation is on the method of the AccountServiceImpl class, but do nothing if the annotation is on AccountService.
I read Spring documentation about other Pointcut tools, but I found nothing to run this Advice.
I miss something?

Thanks for your help
