Hi folks,
I have came up with a logging heirachy problem recently.
The situation looks basically like this:
public abstract class A {
logger = .... A.class;
public void out() {
logger.info("this is out");
}
abstract protected void moreOut();
}
public class B extends A {
logger = ... B.class;
@Override
public void moreOut() {
logger.info("this is moreOut");
}
public static void main(String[] args) {
B name = new B();
name.out();
name.moreUut();
}
}
The output is of course:
0 [main] INFO A - this is out
0 [main] INFO B - this is moreOut
Well, since I use the abstract class as a skeleton, it should be
completely transparent and not appear in log statements.
There seems not to be a reasonable solution except this:
public abstract class A {
public void out() {
getLogger().info("this is out");
}
abstract protected void moreOut();
abstract protected Logger getLogger();
}
public class B extends A {
logger = ... B.class;
@Override
public void moreOut() {
logger.info("this is moreOut");
}
@Override
public Logger getLogger() {
return LoggerFactory.getLogger(B.class);
}
public static void main(String[] args) {
B name = new B();
name.out();
name.moreUut();
}
}
and the output is as desired:
0 [main] INFO B - this is out
0 [main] INFO B - this is moreOut
I'd like to know your opinion on that. Is my solution the best way to go?
Thanks!
