采用线程中断信号量停止线程
采用控制一个中断标识符的方式来停止一个线程:
package thread.test; class InteruptTest extends Thread { volatile boolean stop = false;// 线程中断信号量 public static void main(String args[]) throws Exception { InteruptTest thread = new InteruptTest(); System.out.println("Starting thread..."); thread.start(); Thread.sleep(3000); System.out.println("Asking thread to stop..."); // 设置中断信号量 thread.stop = true; Thread.sleep(3000); System.out.println("Stopping application..."); } public void run() { // 每隔一秒检测一下中断信号量 while (!stop) { System.out.println("Thread is running..."); long time = System.currentTimeMillis(); /* * 使用while循环模拟 sleep 方法,这里不要使用sleep,否则在阻塞时会 抛 * InterruptedException异常而退出循环,这样while检测stop条件就不会执行, 失去了意义。 */ while ((System.currentTimeMillis() - time < 1000)) { } } System.out.println("Thread exiting under request..."); } }
