How to define an aspectj pointcut that picks out all constructors of a class that has a specific annotation?

Question

Here is the annotation:

@Target(value = ElementType.TYPE)
@Retention(value = RetentionPolicy.RUNTIME)
@Inherited
public @interface MyAnnotation {
    String          


        

Answer 1

Your pointcut should look like this:

execution((@MyAnnotation *).new(..))

If the annotation is in another package:

execution((@de.scrum_master.aop.demo.MyAnnotation *).new(..))

Or if you do not want to fully qualify the package:

execution((@*..MyAnnotation *).new(..))

Edit: Okay, some more info about your question in the comment:

Constructor executions have no return value which you could capture in

after() returning(Object myObject) : myJoinpoint()

This only works for methods. So please use

after(Object myObject) returning : myJoinpoint() && this(myObject)

instead if you do need the constructed object for any purpose.
