Java logger that automatically determines caller’s class name

javaloggingstack-trace

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?

Best Solution

The MethodHandles class (as of Java 7) includes a Lookup class that, from a static context, can find and return the name of the current class. Consider the following example:

import java.lang.invoke.MethodHandles;

public class Main {
  private static final Class clazz = MethodHandles.lookup().lookupClass();
  private static final String CLASSNAME = clazz.getSimpleName();

  public static void main( String args[] ) {
    System.out.println( CLASSNAME );
  }
}

When run this produces:

Main

For a logger, you could use:

private static Logger LOGGER = 
  Logger.getLogger(MethodHandles.lookup().lookupClass().getSimpleName());
