Re: [aspectj-users] aspectj help : pointcut annotation binding not work

[Andrew Clement <CLEMAS@xxxxxxxxxx>]

Hi there,

In your pointcut:

public pointcut checkSecurityCallAdd(Security securityAnnotation)
: 
  execution(@Security public * *(..)) && @this(securityAnnotation)

@this(securityAnnotation)

will attempt to bind on the annotation
associated with the *type* containing your secure method,
rather than the method - so it won't
match (as the type isn't annotated).  To bind against the 
annotation for the method you need to
use @annotation:

public pointcut checkSecurityCallAdd(Security securityAnnotation)
: 
  execution(@Security public * *(..)) && @annotation(securityAnnotation)

Adrian has a blog entry with a real
example in:

        http://www.aspectprogrammer.org/blogs/adrian/2005/03/event_driven_ar.html

cheers,
Andy.

Subject	[aspectj-users] aspectj help : pointcut annotation binding not work

Hi, 

I'm beginner on aspectj.
My aspect want to catch method scoped annotation of type Security using
MyFirstWeaveAspect aspect on MyClass class

The AJDT detect the poincut matching but during runtime, the advise is
never 
executing.

Please help me.
Thanks
MAC

Aspect code :
public aspect MyFirstWeaveAspect {
public pointcut checkSecurityCallAdd(Security securityAnnotation) : 
execution(@Security public * *(..)) && @this(securityAnnotation)

before(Security annotation) : checkSecurityCallAdd(annotation){
 if (annotation.style().equals(SecurityType.NORMAL)) {
 System.out.println("NORMAL SECURITY");
 }
 if (annotation.style().equals(SecurityType.PARANOIAC)) {
 System.out.println("PARANOIAC SECURITY");
 }
 if (annotation.style().equals(SecurityType.SIMPLE)) {
 System.out.println("SIMPLE SECURITY");
 } else
 {
 System.out.println("BIZARRE"); 
}
 }
}

Class to weave : 

public class MyClass extends MyBaseClass{

 @Security (style=SecurityType.NORMAL)
 public void doGoodThing () {
 System.out.println("doGoodthing");
 }
