RabbitMQ:Fanout Exchange

一.Fanout Exchange相关介绍

不处理路由键，只需要将简单的将队列绑定到交换机上。

发送到交换机的消息都会被转发到与该交换机绑定的所有队列上。

Fanout交换机转发消息是最快的。

二.消费者

public static void main(String[] args) throws IOException, TimeoutException, InterruptedException {
        //创建一个连接工厂
        ConnectionFactory connectionFactory = new ConnectionFactory();
        connectionFactory.setHost("192.168.10.132");
        connectionFactory.setPort(5672);
        connectionFactory.setVirtualHost("/");
        //创建连接
        Connection connection = connectionFactory.newConnection();
        //通过连接创建一个Channel
        Channel channel = connection.createChannel();
        //创建一个队列
        String exchangeName = "test_fanout_exchange";
        String exchangeType = "fanout";
        String queueName1 = "fanout1";
        String queueName2 = "fanout2";
        String routingKey = "";
        //声明一个交换机
        channel.exchangeDeclare(exchangeName,exchangeType,true,false,false,null);
        //声明队列
        channel.queueDeclare(queueName1,false,false,false,null);
        channel.queueDeclare(queueName2,false,false,false,null);
        //建立交换机、队列的绑定关系
        channel.queueBind(queueName1,exchangeName,routingKey);
        channel.queueBind(queueName2,exchangeName,routingKey);
        //创建一个消费者
        QueueingConsumer consumer = new QueueingConsumer(channel);
        //设置Channel
        channel.basicConsume(queueName1,true,consumer);
        channel.basicConsume(queueName2,true,consumer);
        //获取消息
        while (true){
            QueueingConsumer.Delivery delivery = consumer.nextDelivery();
            String msg = new String(delivery.getBody());
            System.out.println("消费端："+msg);
        }

    }

三.生产者

    public static void main(String[] args) throws IOException, TimeoutException {
        //创建一个连接工厂
        ConnectionFactory connectionFactory = new ConnectionFactory();
        connectionFactory.setHost("192.168.10.132");
        connectionFactory.setPort(5672);
        connectionFactory.setVirtualHost("/");
        //创建连接
        Connection connection = connectionFactory.newConnection();
        //通过连接创建一个Channel
        Channel channel = connection.createChannel();
        //通过Channel发送数据
        channel.basicPublish("test_fanout_exchange","",null,"test fanout exchange".getBytes());
        channel.basicPublish("test_fanout_exchange","",null,"test fanout exchange".getBytes());
        //关闭连接
        channel.close();
        connection.close();
    }
