Question

我在应该显示班级名称和行号的地方出现问号。

这是我的log4j.properties文件

logfile=C:/Softwares/logFiles

log4j.rootLogger=ERROR, generalDebug, generalError

log4j.appender.generalDebug.File=${logfile}/debug.log

日志同时处于DEBUG和ERROR级别。

[ERROR] 2019-04-11 22:40:30,975|0 ?|?| - I'm Writing
[DEBUG] 2019-04-11 22:40:30,975|0 ?|?| - I'm Writing

这是我的代码：

PropertyConfigurator.configure("C:\\Softwares\\ConfigFiles\\log4j.properties");
    Logger logger = Logger.getLogger(Logeverything.class);
    logger.log(Logeverything.class.getCanonicalName(), Level.ERROR, "I'm Writing", null);

有人可以告诉我这是怎么回事吗？

谢谢

使用logger.error("I'm Writing");代替logger.log(Logeverything.class.getCanonicalName(), Level.ERROR, "I'm Writing", null);

Logeverything.java

import org.apache.log4j.Logger;
import org.apache.log4j.PropertyConfigurator;

public class Logeverything {

    static {
        PropertyConfigurator.configure("src/main/resources/ConfigFiles/log4j.properties");
    }

    private static Logger logger = Logger.getLogger(Logeverything.class);

    public static void main(String[] args) {
        logger.error("I'm Writing");
    }
}

$ cat error.log
[ERROR] 2019-04-11 10:56:16,302|0 Logeverything|14| - I'm Writing

Log4j消息中用问号代替类名
