在其他类中调用记录器类的java

Question

static public void setup(String className, Exception e, Level level) {

    System.out.println("className = " + className);
    Logger logger = Logger.getLogger(className);
    logger.setLevel(Level.INFO);



    try {
        fileTxt = new FileHandler("Logging.%u.%g.txt",1024 * 1024, 10, true );
        // create a TXT formatter
        formatterTxt = new SimpleFormatter();
        fileTxt.setFormatter(formatterTxt);

        logger.addHandler(fileTxt);
        logger.log(level, e.toString(), e);
    } catch (IOException | SecurityException ex) {
        System.out.println("SecurityException ");
        Logger logger2=Logger.getLogger(MyLogger.class.getName());
        logger2.addHandler(new ConsoleHandler());
        logger2.log(Level.SEVERE, null, ex);
    }

}

您可以使用java.util.logging.SimpleFormatter的format属性来使用记录器名而不是源类名。

修改启动脚本以设置以下系统属性：

-Djava.util.logging.SimpleFormatter.format="%1$tc %3$s%n%4$s: %5$s%6$s%n"

或者修改logging.properties以包括：

java.util.logging.SimpleFormatter.format=%1$tc %3$s%n%4$s: %5$s%6$s%n
