AOP, annotation-based pointcut and overriden methods

[Romain Wilbert]

Hi,

I have a aspect which declares an annotation based pointcut :

"@annotation(my.package.MyAnnotation)"

I have a spring bean which is abstract and parametrized :

public abstract class MyAbstractBeanBOImpl<T extends MyGenericType> extends
		AbstractBOImpl<T> implements MyAbstractBeanBO {

This bean declares an "update" method :

public T update(T entity) {

I have an typed spring bean which extends MyAbstractBeanBOImpl, and overrides the update method :

@MyAnnotation("XXX")
         @Override
	public MyTypedType update(MyTypedType entity) {

My beans are configured to expose proxies and to proxy target classes with CGLIB.

AOP does not trigger when I call the "update" method from ImageBOImpl.
AOP does trigger if I annotate the "update" method from MyAbstractBeanBOImpl with @MyAnnotation.

This is a issue to me as I want to pass a particular value to my annotation in the child class.

Is this normal behavior ? Why does AOP rely on the parent method signature ?

I took a look at Spring Security because I noticed that this does not behave like this. In that case, an interceptor registers all eligible methods and save the @Secured annotation attribute in a cache, which is read when the aspect is called. I wish I had not to create such mechanism...

Any hint ?
