Class TextFormatter

  • public class TextFormatter
extends java.util.logging.Formatter
    A pattern-driven log formatter. Inspired by Log4j's PatternLayout Set a different output pattern with .format.

    The default format is "%5$tT %3$-5s %2$-20s :: %6$s\n".

    Examples:

    • "%5$tT.%5$tL %3$-5s %2$-20s :: %6$s\n" for milliseconds.
    • "%tF %5$tT.%5$tL %3$-5s %2$-20s :: %6$s\n" for date

    The log message formatting call is: 

         String.format(format, 
                   loggerName,                        // 1
                   loggerNameShort,                   // 2
                   levelOutputName,                   // 3
                   Thread.currentThread().getName(),  // 4
                   new Date(record.getMillis()),      // 5
                   formatted$) ;                      // 6
    where formatted$ is the LogRecord message string after parameters have been processed.
