使用blockingqueue实现的简单生产者消费者模型

1、生产者消费者模型一般用于将复杂的业务逻辑异步化，多个线程来同时处理以提升系统的运行效率，典型的案例就是消息队列。

2、这里我使用的是blockingqueue，java提供的一种阻塞队列的实现，用来简单的实现生产者消费者模型。

3、生产者代码

public class Producer implements Runnable {

	private BlockingQueue<String> blockingQueue;

	public Producer() {
	}

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

	public void run() {
		try {
			String temp = "生产线程" + Thread.currentThread().getName();
			blockingQueue.put(temp);
		} catch (InterruptedException e) {
			e.printStackTrace();
		}

	}
}

4、消费者代码

public class Consumer implements Runnable {

	private BlockingQueue<String> blockingQueue;

	public Consumer() {
	}

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

	public void run() {
		try {
			// 取出阻塞队列中的消息
			String temp = blockingQueue.take();
			// 打印结果消息
			System.out.println("消费线程"+Thread.currentThread().getName()+" 消费 "+temp);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

}

5、测试代码

public class ProducerConsumerTest {

	public static void main(String[] args) {
		BlockingQueue<String> blockingQueue = new LinkedBlockingQueue<String>();
		Producer producer = new Producer(blockingQueue);
		Consumer consumer = new Consumer(blockingQueue);
		for(int i = 0; i < 5; i++){
			//生产者线程
			new Thread(producer).start();
			//消费者线程
			new Thread(consumer).start();
		}
	}
}
