java - log4j 以编程方式获取控制台附加程序以将 System.out 包含到文件中

Question

我正在以编程方式使用 log4j。它似乎在控制台消息之外工作。不出现 System.out 消息。 logger.info/error/etc 都出现在文件中。不能记录System.out信息吗？我做错了什么？

   Logger logger = Logger.getRootLogger();
            logger = Logger.getLogger("com.mycodebase");

  ConsoleAppender consoleAppender = new ConsoleAppender();
        PatternLayout consolePatternLayout = new PatternLayout();
        consolePatternLayout.setConversionPattern("%d{dd MMM yyyy} %d{HH:mm:ss}: %5p %c{1}:%L - %m%n");
        consoleAppender.setLayout(consolePatternLayout);
        consoleAppender.setName("Iridium Suite Console appender");
        consoleAppender.setThreshold(Level.INFO);
        consoleAppender.activateOptions();

        //Create Iridium Suite log file appender
        isAppender = new RollingFileAppender();
        isAppender.setFile(logFileName);
        PatternLayout isPatternLayout = new PatternLayout();
        isPatternLayout.setConversionPattern("%d{dd MMM yyyy} %d{HH:mm:ss}: %5p %c{1}:%L - %m%n");
        isAppender.setLayout(isPatternLayout);
        isAppender.setThreshold(Level.INFO);
        isAppender.setName("log appender");
        isAppender.setAppend(true);
        isAppender.setMaxBackupIndex(0);
        isAppender.setMaxFileSize("2MB");
        isAppender.activateOptions();

        Logger.getRootLogger().addAppender(consoleAppender);
        Logger.getRootLogger().addAppender(isAppender);

ConsoleAppender 用于将日志消息定向到 stdout，但反之则不然。人们在这里想出了很好的解决方案: log4j redirect stdout to DailyRollingFileAppender
