主方法开启线程

生产者生产连接 ,消费者获取连接

/**
 * 线程池阻塞队列
 */
public class Test {
    public static void main(String[] args) {
        BlockingQueue<String> blockingQueue = new LinkedBlockingQueue<String>(10);

        ProducerThread producerThread = new ProducerThread(blockingQueue);
        ConsumerThread consumerThread = new ConsumerThread(blockingQueue);

        Thread p = new Thread(producerThread);
        Thread c = new Thread(consumerThread);

        p.start();
        c.start();

        try {
            //等待10秒
            Thread.sleep(1000*10);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        producerThread.stop();

    }
}

生产者线程

/**
 * 生产者添加队列
 */
class ProducerThread implements Runnable{

    public BlockingQueue<String> blockingQueue;
    public volatile Boolean FLAG = true;
    AtomicInteger atomicInteger =new AtomicInteger();

    public ProducerThread(BlockingQueue<String> blockingQueue){
        this.blockingQueue = blockingQueue;
    }

    @Override
    public void run() {
        System.out.println("生产者线程已经启动");

        try {
            while (FLAG){
                //i++的意思,保证安全
                String data = atomicInteger.incrementAndGet() +"";

                   boolean offer =  blockingQueue.offer(data,2, TimeUnit.SECONDS);
                   if (offer){
                       System.err.println("生产者存入队列成功!data:" + data);
                   }else {
                       System.err.println("生产者存入队列失败!data:" + data);
                   }
                Thread.sleep(1000);
            }
        } catch (InterruptedException e) {
            e.printStackTrace();
        } finally {
            System.out.println("生产者生产结束");
        }


    }

    //线程停止
    public void stop(){
        this.FLAG = false;
    }
}

消费者线程

/**
 * 消费者消费队列
 */
class ConsumerThread implements Runnable{

    public BlockingQueue<String> blockingQueue;
    public volatile Boolean FLAG = true;
    AtomicInteger atomicInteger =new AtomicInteger();

    public ConsumerThread(BlockingQueue<String> blockingQueue){
        this.blockingQueue = blockingQueue;
    }


    @Override
    public void run() {
        System.out.println("消费者线程启动");
        try {
            while (FLAG){
                String data = blockingQueue.poll(2, TimeUnit.SECONDS);
                if (data == null){
                    System.out.println("超过两秒时间没有获取到");
                    FLAG = false;
                    return;
                }
                System.out.println("消费者获取队列data:"+data);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }finally {
            System.out.println("消费结束");
        }

    }
}
