javaloggingstack-trace

Java logger that automatically determines caller's class name

public static Logger getLogger() {
    final Throwable t = new Throwable();
    final StackTraceElement methodCaller = t.getStackTrace()[1];
    final Logger logger = Logger.getLogger(methodCaller.getClassName());
    logger.setLevel(ResourceManager.LOGLEVEL);
    return logger;
}

This method would return a logger that knows the class it's logging for. Any ideas against it?

Solution

  • I guess it adds a lot of overhead for every class. Every class has to be 'looked up'. You create new Throwable objects to do that... These throwables don't come for free.
