如何在使用 Apache 的 Tailer 包监控文件时获取文件名？

Question

我可以使用org.apache.commons.io.input.Tailer包来跟踪多个日志文件，但无法获得它们的名称。可用的侦听器 (TailerListenerAdapter( 不提供任何方法来获取发生事件的文件的名称。

public class ApacheLogFileTailer {
public static void main(String[] args) {
    String filelog1 = "C:\Users\eventfile1.log";
    String filelog2 = "C:\Users\eventfile2.log";
    ApacheLogFileTailerListener listener = new ApacheLogFileTailerListener();
    Tailer tailer1 = new Tailer(new File(filelog1), listener, 50);
    Thread tailerThread1 =new Thread(tailer1);
    tailerThread1.start();
    Tailer tailer2 = new Tailer(new File(filelog2), listener, 50);
    Thread tailerThread2 =new Thread(tailer2);
    tailerThread2.start();
    }
}
public class ApacheLogFileTailerListener extends TailerListenerAdapter {
@Override
public void handle(String line) {
    // How to get the name of the file changed ?? 
    System.out.println("Log file change "+line);
    super.handle(line);
   }
}

请指教。

一种方法可能是设置线程名称

    public class ApacheLogFileTailer {
    public static void main(String[] args) {
    String filelog1 = "C:\Users\eventfile1.log";
    String filelog2 = "C:\Users\eventfile2.log";
    ApacheLogFileTailerListener listener = new ApacheLogFileTailerListener();
    Tailer tailer1 = new Tailer(new File(filelog1), listener, 50);
    Thread tailerThread1 =new Thread(tailer1);
    tailerThread1.setName("eventfile1.log");
    tailerThread1.start();
    Tailer tailer2 = new Tailer(new File(filelog2), listener, 50);
    Thread tailerThread2 =new Thread(tailer2);
    tailerThread1.setName("eventfile2.log");
    tailerThread2.start();
    }
    }
   public class ApacheLogFileTailerListener extends TailerListenerAdapter {
   @Override
   public void handle(String line) {
    // How to get the name of the file changed ?? 
    System.out.println("Log file change "+line);
    System.out.println("Log file change name "+Thread.currentThread().getName());
    super.handle(line);
   }
}
