带有注释的类的子类的@AspectJ切入点 [英] @AspectJ pointcut for subclasses of a class with an annotation

问题描述

我正在寻找一个切入点，该切入点与类中具有特定注释的子类的类中的方法执行相匹配.出色的 AspectJ速查表帮助我创建了以下切入点:

I'm looking for a pointcut that matches method executions in classes that subclass a class with a specific annotation. The excellent AspectJ cheat sheet helped me to create the following pointcut:

within(@my.own.annotations.AnnotationToMatch *) && execution(* *(..))

这与带有@AnnotationToMatch的类A的所有方法调用匹配，但与扩展了A的类B的方法匹配.我如何将两者都匹配?

This matches all method calls of a class A that carries the @AnnotationToMatch, but not method of a class B that extends A. How can I match both?

推荐答案

public aspect AnnotatedParentPointcutAspect {   

//introducing empty marker interface
declare parents : (@MyAnnotation *) implements TrackedParentMarker;

public pointcut p1() : execution(* TrackedParentMarker+.*(..));

before(): p1(){
    System.out.println("Crosscutted method: "
            +thisJoinPointStaticPart.getSignature().getDeclaringTypeName()
            +"." 
            +thisJoinPointStaticPart.getSignature().getName());
}
}
