I just want to point out these each of these is somewhat of a rube 
solution.  A better approach is to use the logger method with parameters:

<http://docs.oracle.com/javase/7/docs/api/java/util/logging/Logger.html#log%28java.util.logging.Level,%20java.lang.String,%20java.lang.Object[]%29>

All of the other ideas mentioned above call the toString() method of 
every object concerned, and also use a StringBuilder to construct a new 
string.  Both of these can have considerable overhead.

Whereas the log method with parameters doesn't invoke any of these if 
the log level test does not pass, thus being much "lighter weight" at 
run time.

The parameter substitution is "{n}" where n is a number encoded as a 
string >= 0.  Example:

   logger.log( Level.FINEST, "myVar = {0}, otherVar = {1}", myVar,
                otherVar );

Read the bit here (at the TOP of the page) where it talks about "msg 
argument".

<http://docs.oracle.com/javase/7/docs/api/index.html?java/util/logging/Logger.html>

Back on topic: no I don't know of a macro that auto generates those for 
you. :)
