RabbitMQ經過Exchange.fanout、不一樣的隊列綁定同一個Exchange實現多播處理

消費者1:

 static void Main(string[] args)
        {
            ConnectionFactory factory = new ConnectionFactory()
            {
                HostName = "192.168.254.40",
                UserName = "admin",
                Password = "admin",
            };

            //第一步：建立connection
            var connection = factory.CreateConnection();

            //第二步：建立一個channel
            var channel = connection.CreateModel();

            //第三步：申明交換機【由於rabbitmq已經有了自定義的ampq default exchange】
            channel.ExchangeDeclare("myfanoutexchange", ExchangeType.Fanout, true, false, null);

            //第四步：建立一個隊列(queue)
            channel.QueueDeclare("myfanoutqueue", true, false, false, null);

            //將queue綁定到exchange之上。。。。
            channel.QueueBind("myfanoutqueue", "myfanoutexchange", string.Empty, null);

            EventingBasicConsumer consumer = new EventingBasicConsumer(channel);

            consumer.Received += (sender, e) =>
            {
                var msg = Encoding.UTF8.GetString(e.Body);

                Console.WriteLine(msg);
            };

            channel.BasicConsume("myfanoutqueue", true, consumer);

            Console.WriteLine("consumer1 端啓動完畢！！！");

            Console.Read();
        }

消費者2：

static void Main(string[] args)
        {
            ConnectionFactory factory = new ConnectionFactory()
            {
                HostName = "192.168.254.40",
                UserName = "admin",
                Password = "admin",
            };

            //第一步：建立connection
            var connection = factory.CreateConnection();

            //第二步：建立一個channel
            var channel = connection.CreateModel();

            //第三步：申明交換機【由於rabbitmq已經有了自定義的ampq default exchange】
            channel.ExchangeDeclare("myfanoutexchange", ExchangeType.Fanout, true, false, null);

            //第四步：建立一個隊列(queue)
            channel.QueueDeclare("myfanoutqueue2", true, false, false, null);

            //將queue綁定到exchange之上。。。。
            channel.QueueBind("myfanoutqueue2", "myfanoutexchange", string.Empty, null);

            EventingBasicConsumer consumer = new EventingBasicConsumer(channel);

            consumer.Received += (sender, e) =>
            {
                var msg = Encoding.UTF8.GetString(e.Body);

                Console.WriteLine(msg);
            };

            channel.BasicConsume("myfanoutqueue2", true, consumer);

            Console.WriteLine("consumer2 端啓動完畢！！！");

            Console.Read();
        }

生產者:

 static void Main(string[] args)
        {
            ConnectionFactory factory = new ConnectionFactory()
            {
                HostName = "192.168.254.40",
                UserName = "admin",
                Password = "admin",
            };

            //第一步：建立connection
            var connection = factory.CreateConnection();

            //第二步：建立一個channel
            var channel = connection.CreateModel();

            for (int i = 0; i < 10; i++)
            {
                var msg = Encoding.UTF8.GetBytes(string.Format("{0} :{1}", i, "你好"));

                //第五步：發佈消息
                channel.BasicPublish("myfanoutexchange", routingKey: string.Empty, basicProperties: null, body: msg);

                Console.WriteLine(i);
            }
        }

先啓動消費端進行綁定，生產者發送消息到exchange，兩個消費端綁定不一樣的隊列都獲得了相同的消息
