Logging a-la-printf with java

My C backgroud make me very unhappy when logging with java. I always have to type

log.info(String.format(“Logging field %s: with value: %d”, field, value));

Today I decide to extend the default log4j logger implementing my log.info & co using java varags.

I created two classes:
CustomLoggerFactory implements LoggerFactory:



@implement makeNewLoggerInstance(String name)Â return new MyLogger(name);

MyLogger extends Logger:



private MyLoggerFactory factory = new MyLoggerFactory();
@override getLogger(Class clazz)
info(String format, Object... params)

Now I can use MyLogger

MyLogger log = (MyLogger) MyLogger.getLogger(getClass());

log.info("Test base:string %s int %d" , "string", 0);
