发布的时候是申明了交换器和队列并绑定，然而订阅的时候只需要声明队列就可。从下面代码能看到，捕获到异常的时候，会把消息送到自定义的“死信队列”里，由另外的JOB进行定时重发，因此，finally是应答成功的。
/// <summary> /// 获取Model /// </summary> /// <param>队列名称</param> /// <param></param> /// <returns></returns> private static IModel GetModel(string queue, bool isProperties = false) { return ModelDic.GetOrAdd(queue, value => { var model = _conn.CreateModel(); QueueDeclare(model, queue, isProperties); //每次消费的消息数 model.BasicQos(0, 1, false); ModelDic[queue] = model; return model; }); } /// <summary> /// 接收消息 /// </summary> /// <typeparam></typeparam> /// <param>队列名称</param> /// <param></param> /// <param>消费处理</param> /// <param></param> public void Subscribe<T>(string queue, bool isProperties, Action<T> handler, bool isDeadLetter) where T : class { //队列声明 var channel = GetModel(queue, isProperties); var consumer = new EventingBasicConsumer(channel); consumer.Received += (model, ea) => { var body = ea.Body; var msgStr = body.DeserializeUtf8(); var msg = msgStr.FromJson<T>(); try { handler(msg); } catch (Exception ex) { ex.GetInnestException().WriteToFile("队列接收消息", "RabbitMq"); if (!isDeadLetter) PublishToDead<DeadLetterQueue>(queue, msgStr, ex); } finally { channel.BasicAck(ea.DeliveryTag, false); } }; channel.BasicConsume(queue, false, consumer); }
下次是本机测试的发布速度截图：
快的时候有1.9K/S，慢的时候也有1.7K/S
