Hi to all,
I am pretty new to AspectJ and was wondering about a thing...
I saw some nice examples like logging methods the start and the end. In that
example there was just an System.out used. I was trying that using log4j but
did not get along directly.
After some googling I found a kind of reflective workaround so it looks like
this;
import org.apache.log4j.Logger;
import org.aspectj.lang.Signature;
import de.lala.Klasse1
import de.lala.Klasse2;
import de.lala.Klasse3;
public aspect Performance
{
pointcut classes() : within(Klasse1) || within (Klasse2) ||
within(Klasse3);
pointcut constructors() : classes() && execution(new(..));
pointcut methods() : classes() && execution (* *(..));
before () : constructors() || methods()
{
Signature<http://www.google.com/search?hl=en&q=allinurl%3Asignature+java.sun.com&btnI=I%27m%20Feeling%20Lucky>
sig = thisJoinPointStaticPart.getSignature();
Logger logger = Logger.getLogger(sig.getDeclaringType());
logger.info("----- start:"+sig);
}
after () : constructors() || methods()
{
Signature<http://www.google.com/search?hl=en&q=allinurl%3Asignature+java.sun.com&btnI=I%27m%20Feeling%20Lucky>
sig = thisJoinPointStaticPart.getSignature();
Logger logger = Logger.getLogger(sig.getDeclaringType());
logger.info("----- end:"+sig);
}
}
The disadvantage is that I need the aspect-library to run my program.
Is there any way to use the static logger field provided in eaqch class of its
own for the advice? If yes, what is the correct syntax for that?
Thanks for useful hints in advance
Malte
