多線程中線程的殺除問題

在拿到一個項目或者需求之後,都會根據需求來先把架構設計完好,設計架構是有時會遇到多個線程的問題,自然就會遇到線程沒有殺除成功的問題,

若是採用一個volatile 類型的thread,然後在殺除她的時候,將正在run的thread傳給一個臨時變量,將臨時變量賦予null.

 

public class SocketThread extends Thread{
    private volatile Thread runner;
   
    private Socket socket;
   
    public SocketThread(){
       
    }

    public SocketThread(Socket socket){
      
        this.socket = socket;
        this.runner = null;

    }
    public synchronized void startChecking(){
        if (runner == null) {
            runner = new Thread(this);
           
            runner.start();
        }
    }

    public synchronized void stopChecking(){
        if(runner != null){
            Thread moribund = runner;
            if (socket != null && socket.isConnected()) {
                try {
                    socket.close();
                } catch (IOException e) {
                    // do nothing
                }
            }
            socket = null;
            runner = null;
            moribund.interrupt();
        }
    }

public void run(){

    while (Thread.currentThread() == runner) {

 

// do something

   }

 

}

 

}

 

這樣的話可以解決thread的殺除問題,如有異意,請提出.
