Pointcut intercepting methods with annotated arguments

[jarr]

Is it possible to write a pointcut to intercept execution of some method which has some of its arguments annotated with certain annotation. For example method declared as follows:

void someMethod(@SomeAnnotation String arg1) {...}

It would be nice if pointcut like this would be possible:

execution(* *->*(@SomeAnnotation *))

or even better:

execution(* *->*(.., @SomeAnnotation *, ..)) - it would mean, that pointcut should match execution of any method with any of its arguments being annotated with @SomeAnnotation.

If such pointcut worked it would be trivial to implement an aspect checking not null conditions on method arguments:
void exampleMethod(String nullable, @NotNull String notNullable) {...}

Hi!

Unfortunately, we currently don't support this feature.

I have created a Jira issue for adding this:

https://jira.jboss.org/jira/browse/JBAOP-711

[kabirkhan]

Actually we do and we have test http://anonsvn.jboss.org/repos/jbossas/branches/Branch_AOP_1_5/aop/src/resources/test/annotatedparams/jboss-aop.xml

I've closed the JIRA issue

Ooops...
Sorry, my mistake!

Thanks for reply.

Actually this test http://anonsvn.jboss.org/repos/jbossas/branches/Branch_AOP_1_5/aop/src/resources/test/annotatedparams/jboss-aop.xml is not for the case I was asking about.

In this test interceptor intercepts methods with with parameter that have an annotation on its type.

But I would like to intercept methods with annotation on method parameter itself. Something like this:

void someMethod(@NotNull String message) {
...
}

Here annotation is not on the type of parameter, but on the parameter itself.
Such annotations are possible and are sometimes used, for example in Spring MVC 2.5 for mapping request parameters to method parameters:
