RabbitMQ---fanout广播模型

public class Provider {
    public static void main(String[] args) throws IOException {
        Connection connection = RabbitMQUtil.getConnection();
        Channel channel = connection.createChannel();
        //通道声明交换机  参数1：交换机名称(不存在则创建) 参数2：交换机类型  fanout：广播类型
        channel.exchangeDeclare("testForFanout","fanout");
        //发送消息
        channel.basicPublish("testForFanout","",null,"fanout".getBytes());
        RabbitMQUtil.closeAll(channel,connection);
    }
}

因为是广播模型，绑定同一个交换机的消费者就可以收到相同的消息，只是消费者的业务处理可能不同，因此简略，此处只有一个消费者

public class Consumer1 {
    public static void main(String[] args) throws IOException {
        Connection connection = RabbitMQUtil.getConnection();
        Channel channel = connection.createChannel();
        //通道绑定交换机
        channel.exchangeDeclare("testForFanout","fanout");
        //临时队列
        String queue = channel.queueDeclare().getQueue();
        //绑定交换机和队列
        channel.queueBind(queue,"testForFanout","");
        //消费消息
        channel.basicConsume(queue,true,new DefaultConsumer(channel){
            @Override
            public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body) throws IOException {
                System.out.println("消费者1："+ new String(body));
            }
        });
    }
}
