Log4j无法打印到文件或标准输出

Question

我刚下载了Log4j,我正试图测试它.我复制了一个样本属性文件,从这里打印到stdout和一个文件,但它没有.

这是我的代码:

public class ClientTest {
    //static CanvasFrame canvas = new CanvasFrame("Web Cam");

    static Logger logger = Logger.getLogger(ClientTest.class);
    public static void main(String [] args) {

        BasicConfigurator.configure();

        logger.debug("HERPADERP");

        Client bob = new Client("localhost", 6789);
        bob.startRunning();

    }
}

和log4j.properties:

# Root logger option
log4j.rootLogger=INFO, file, stdout

# Direct log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=Log/log.log
log4j.appender.file.MaxFileSize=1MB
log4j.appender.file.MaxBackupIndex=1
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

# Direct log messages to stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

创建了log.log文件,但没有写入任何内容......

任何人都可以找到我错的地方吗？谢谢 !

您的记录器级别设置为 INFO。您正在使用调试语句。改变

log4j.rootLogger=INFO, file, stdout

到

log4j.rootLogger=DEBUG, file, stdout
