JAVA正確地停止一個線程__JAVA

如何正確停止線程

關於如何正確停止線程，這篇文章(how to stop thread)給出了一個很好的答案, 總結起來就下面3點（在停止線程時）：

1. 使用violate boolean變數來標識線程是否停止

2. 停止線程時，需要調用停止線程的interrupt()方法，因為線程有可能在wait()或sleep(), 提高停止線程的即時性

3. 對於blocking IO的處理，盡量使用InterruptibleChannel來代替blocking IO

 

核心如下：

 

If you are writing your own small thread then you should follow the following example code.

    private volatile Thread myThread;    public void stopMyThread() {        Thread tmpThread = myThread;        myThread = null;        if (tmpThread != null) {            tmpThread.interrupt();        }    }    public void run() {        if (myThread == null) {           return; // stopped before started.        }        try {            // all the run() method's code goes here            ...            // do some work            Thread.yield(); // let another thread have some time perhaps to stop this one.            if (Thread.currentThread().isInterrupted()) {               throw new InterruptedException("Stopped by ifInterruptedStop()");            }            // do some more work            ...        } catch (Throwable t) {           // log/handle all errors here        }    }
