Java Log4j创建动态文件

我有一个文件处理JAVA代码，在处理文件时，我想记录所有的文件处理细节，比如文件有这几行，它在一个单独的日志文件中有一些“Hello”字符串，用于处理每个文件

我在这里尝试的代码工作正常，但是如果我有两个文件，比如file1.txt和file2.txt，记录器会在log_file1.log中记录file1.txt的详细信息，然后在log_file2.log中记录file2.txt时，它也会在log_file2.log中保留log_file1.log的内容

File1.txt

Hello How are you
Hello How are you

Hello How are you
Hello How are you
Hello How are you

日志文件1.log

it has 2 lines and 2 Hello Strings

it has 2 lines and 2 Hello Strings
it has 3 lines and 3 Hello Strings

File2.txt

Hello How are you
Hello How are you

Hello How are you
Hello How are you
Hello How are you

日志文件2.log

it has 2 lines and 2 Hello Strings

it has 2 lines and 2 Hello Strings
it has 3 lines and 3 Hello Strings

我尝试过的代码：

public class DummyLog
{
    private static PatternLayout patternLayout = new PatternLayout("%d{ISO8601}\t%p\t%c\t%m%n");

    public static Logger getLogger(String fileName, Class clazz) throws Exception
        {
            fileName = "D:/New folder/log-properties/" + fileName + ".log";
            Logger logger = Logger.getLogger(clazz);
            FileAppender appender = new DailyRollingFileAppender(patternLayout,
                            fileName, "'.'yyyy-MM-dd");
            logger.addAppender(appender);
            logger.setLevel(Level.DEBUG);
            return logger;
        }
}

public class TestDummyLog
{
    public static void main(String args[]) throws Exception
    {
        for(int i = 2;i > 0;i--)
        {           
                 String loggerName = "Log1_"+new SimpleDateFormat("yyyyddMMHHmmssSSS").format(new Date());
                 Logger logger = DummyLog.getLogger(loggerName, TestDummyLog.class);
                 logger.info("Joseph Micheal TestLogger:" +new SimpleDateFormat("yyyyddMMHHmmssSSS").format(new Date()));
                 new TestLoggerChild().getChileStuff(loggerName);
                 Thread.sleep(6000);
        }

    }
}

public class TestLoggerChild
{
public static Logger logger = null;
public void getChileStuff(String fileName) throws Exception
{
    logger = DummyLog.getLogger(fileName,TestLoggerChild.class);
    logger.info("Child Sample info message"+new SimpleDateFormat("yyyyddMMHHmmssSSS").format(new Date()));
    logger.info("Class :::::: TestLoggerChild.class");
    logger.debug("fileName @@@@@@@@@@@@@:" + fileName);
    logger.info("Sample info message");
    logger.warn("Sample warn message");
    logger.error("Sample error message");
    logger.info("Sample info message ");
    logger.info("Class :::::: TestLoggerChild.class");
}
}

主类：

public class DummyLog
{
    private static PatternLayout patternLayout = new PatternLayout("%d{ISO8601}\t%p\t%c\t%m%n");

    public static Logger getLogger(String fileName, Class clazz) throws Exception
        {
            fileName = "D:/New folder/log-properties/" + fileName + ".log";
            Logger logger = Logger.getLogger(clazz);
            FileAppender appender = new DailyRollingFileAppender(patternLayout,
                            fileName, "'.'yyyy-MM-dd");
            logger.addAppender(appender);
            logger.setLevel(Level.DEBUG);
            return logger;
        }
}

public class TestDummyLog
{
    public static void main(String args[]) throws Exception
    {
        for(int i = 2;i > 0;i--)
        {           
                 String loggerName = "Log1_"+new SimpleDateFormat("yyyyddMMHHmmssSSS").format(new Date());
                 Logger logger = DummyLog.getLogger(loggerName, TestDummyLog.class);
                 logger.info("Joseph Micheal TestLogger:" +new SimpleDateFormat("yyyyddMMHHmmssSSS").format(new Date()));
                 new TestLoggerChild().getChileStuff(loggerName);
                 Thread.sleep(6000);
        }

    }
}

public class TestLoggerChild
{
public static Logger logger = null;
public void getChileStuff(String fileName) throws Exception
{
    logger = DummyLog.getLogger(fileName,TestLoggerChild.class);
    logger.info("Child Sample info message"+new SimpleDateFormat("yyyyddMMHHmmssSSS").format(new Date()));
    logger.info("Class :::::: TestLoggerChild.class");
    logger.debug("fileName @@@@@@@@@@@@@:" + fileName);
    logger.info("Sample info message");
    logger.warn("Sample warn message");
    logger.error("Sample error message");
    logger.info("Sample info message ");
    logger.info("Class :::::: TestLoggerChild.class");
}
}

是否有必要使用相同的类别（TestLoggerChild.class）？如果您传递自定义参数化字符串，它必须工作：DummyLog.getLogger（文件名，“Category”+i）
