如何在java中使用多线程中的log4j？ [英] how to use log4j in Multithread using java?

问题描述

我想使用log4j为每个线程写日志，日志文件名为workthread..log，第一个线程打印日志文件为workthread-1.log，第二个线程为workthread-2.log等等。

I want to write log for each thread using log4j and log file name will be "workthread..log",first thread print log on file "workthread-1.log" and second thread on "workthread-2.log" and so on.

class MyRunnable implements Runnable 
  {
       private Logger logger=null;

       public MyRunnable()
        {
            DOMConfigurator.configure(this.getClass().getClassLoader().getResource(LOG4J_FILEPATH));
            logger =Logger.getLogger(classname);
        }

        public void run() 
        {
          logger.info("Important job running in MyRunnable"+Thread.currentThread().getName());
        }
   }


public class TestThreads 
{
    public static void main (String [] args) 
     {
        Thread[] worker=new Thread[3];
        MyRunnable r = new MyRunnable();

        for(int i=0;i<3;i++) {
           worker[i]=new Thread(r);
           worker[i].start();
        }


    }
}//class

请帮帮我？

推荐答案

也许你可以试试这样的东西：

perhaps you could try somezthing like this:

logger = Logger.getLogger(classname);
logger.removeAllAppenders();                                        
logger.addAppender(new FileAppender(layout, "your-thread-name.log", true)); 

你可以用thread.getName（）这样的东西来获取你的线程的名称。 ）

you could get the name of your thread with something like "thread.getName()" i think ;)
