Interrupt中断线程

 

package com.wistron.swpc.ecs.util;

public class WrongWayStopThread extends Thread{

    public static void main(String[] args) {
        WrongWayStopThread thread = new WrongWayStopThread();
        System.out.println("Starting thread...");
        thread.start();
        try {
            Thread.sleep(3000);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        
        System.out.println("Interrupting thread... ");
        thread.interrupt();
        
        try {
            Thread.sleep(3000);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        
        System.out.println("Stopping application...");
    }
    
    public void run(){
        while(!this.isInterrupted()){
            System.out.println("Thread is running...");
            //下面几行代码是模拟Thread.sleep(1000),至于为啥不用sleep是因为用了sleep无法正确中断线程
            long time = System.currentTimeMillis();
            while(System.currentTimeMillis()-time < 1000){
              //减少屏幕输出的空循环
            }
        }
    }

}

运行结果：

Starting thread...
Thread is running...
Thread is running...
Thread is running...
Thread is running...
Interrupting thread... 
Stopping application...

上面模拟的sleep的方法换成sleep

package com.wistron.swpc.ecs.util;

public class WrongWayStopThread extends Thread{

    public static void main(String[] args) {
        WrongWayStopThread thread = new WrongWayStopThread();
        System.out.println("Starting thread...");
        thread.start();
        try {
            Thread.sleep(3000);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        
        System.out.println("Interrupting thread... ");
        thread.interrupt();
        
        try {
            Thread.sleep(3000);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        
        System.out.println("Stopping application...");
    }
    
    public void run(){
        while(!this.isInterrupted()){
            System.out.println("Thread is running...");
            //下面几行代码是模拟Thread.sleep(1000),至于为啥不用sleep是因为用了sleep无法正确中断线程
            /*long time = System.currentTimeMillis();
            while(System.currentTimeMillis()-time < 1000){
              //减少屏幕输出的空循环
            }*/
            
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }

}

运行结果：

Starting thread...
Thread is running...
Thread is running...
Thread is running...
Interrupting thread... 
java.lang.InterruptedException: sleep interrupted
    at java.lang.Thread.sleep(Native Method)

换成sleep之后不能结束线程
