How can i log every method called in a class automatically with log4j

Question

I have a class with database calls, and I generally want to log every method called (with arguments) in this class with log4j:

logger.debug(\"foo(id=\"+id+\") in

Try @Loggable annotation and an AspectJ aspect from jcabi-aspects (I'm a developer):

@Loggable(Loggable.INFO)
public String load(URL url) {
  return url.openConnection().getContent();
}

All method calls are logged through SLF4J.
