Re: [aspectj-users] within pointcut only matches 'phisically'

[Simone Gianni <simoneg@xxxxxxxxxx>]

Hi Martin,
yes, within pointcuts are there exactly to do this, define the "other
end" of the call. So, yes, it is intended. They are most useful with the
call pointcut, for example :

Object around() : call(* DomainBean+.get*()) && within(WebExposedService) {
  if (doSomeSecurityChecks()) {
    return proceed();
  } else {
    throw new SecurityException("You cannot access this method from the
web");
  }
}

This avoids making the security check for each call to each bean method,
but limits it for calls made from a web service.
