Preprocessor logging statements in java

for example I want to replace before compilation:

#debug("${enclosing_method} this is debug message for " + u开发者_如何学PythonserName)

with:

if (log.isDebugEnabled())
{
  log.debug("<real method name> this is debug message for " + userName);
}

Don't. Use slf4j instead which allows you to avoid the check with {}.

Consider using log4j if your example reflects your primary aim.

Quote needed: Preprocessor usage is bad OO practice could be of interest as well.
