理解中断
中断可以理解为线程的一个标识位属性，它表示一个运行中的线程是否被其他线程进行了中断操作（通过调用该线程的interrupt()进行操作）。
运行中的线程自身通过检查是否被中断进行响应，
1.线程通过isInterrupted()来进行判断是否被中断
2.线程调用静态方法Thread.interrupted()对当前线程的中断标识位进行复位。
如果该线程处于终结状态，即使该线程被中断过，在调用该线程对象的isInterrupted()时依旧为返回false.
许多声明抛出InterruptedException的方法（例如 Thread.sleep(long millis)方法）这些方法抛出InterruptedException之前，java虚拟机会先将该线程的中断标示位清除，然后抛出interruptedException,此时调用isInterrupted()方法将会返回false.
package com.qdb.thinkv.thread.base; import java.util.concurrent.TimeUnit; import com.qdb.thinkv.thread.utils.SleepUtils; public class Interrupted { public static void main(String[] args) throws Exception { //Sleep不停的尝试睡眠 Thread sleepThread=new Thread(new SleepRunner(),"SleepRunner"); sleepThread.setDaemon(true); //Busy不停的运行 Thread busyThread=new Thread(new BusyRunner(),"BusyRunner"); busyThread.setDaemon(true); sleepThread.start(); busyThread.start(); //休眠5秒 TimeUnit.SECONDS.sleep(5); sleepThread.interrupt(); busyThread.interrupt(); System.out.println("SleepThread interrupted is "+sleepThread.isInterrupted()); System.out.println("BusyThread interrupted is "+busyThread.isInterrupted()); SleepUtils.second(2); } static class SleepRunner implements Runnable { public void run() { while(true){ SleepUtils.second(10); } } } static class BusyRunner implements Runnable { public void run() { while(true){ } } } }
