Question

如果线程在run（）完成或有异常时死亡，为什么我的日志会不断添加数字。例如，我有一个线程，在每个循环迭代中打开一个新线程并通过套接字发送一些东西。我的问题，线程正在消亡吗？

class otherClass implements Runnable {
    private static Logger logger = LogManager.getLogger(otherClass.class);  


    String dir_dest = "localhost";
    Integer port_dest = 8888;


    public ServerExecuter(){            
        Thread miHilo = new Thread(this);       
        miHilo.start(); 

    }   

    public void run() {
        try {

            while (true) {
                Socket sock = server.accept();

                BufferedReader in= new BufferedReader(new InputStreamReader(miSocket.getInputStream(), "UTF8"));
                String msg = in.readLine();
                logger.info(msg);


                oneClass ex = new oneClass();           

                if (ex.isClose()) {
                    sock.close();
                }

            }

        } catch (IOException e) {
            e.printStackTrace();
        }       
    }

}




public class onClass implements Runnable {
    private static Logger logger = LogManager.getLogger(oneClass.class);

    private String host = "localhost";
    private Integer port = 9999;

    public oneClass(){  

        Thread my_thread = new Thread(this);        
        my_thread.start();          
    }   

    public void run() {

        socket = new Socket(host, port);
        DataOutputStream out = new DataOutputStream(socket .getOutputStream());
        msg = "Hi";
        out.writeBytes(msg);

        socket.close();

        logger.info("thread finish");

   }    
    public boolean isClose() {
        return close;
    }

    public void setClose(boolean close) {
        this.close = close;
    }   

}

我的代码与此类似，它在控制台中打印以下内容：

11:22:50.810 [Thread-2] INFO  
11:22:50.811 [Thread-92] INFO 
11:22:50.813 [Thread-92] INFO - thread finish
11:22:50.937 [Thread-2] INFO  
11:22:50.938 [Thread-93] INFO 
11:22:50.947 [Thread-93] INFO  - thread finish

线程名称由ThreadFactory分配。 Java默认使用＆＃34; Thread-X＆＃34;其中X是递增的索引。每个新线程都会获得一个新索引。具有循环的线程（线程-2）不会完成/死亡，但其他线程似乎是（如果可以信任日志记录）
