RabbitMQ 消费端 Client CPU 100%的解决办法

 Func<bool> run = () =>
            {
                try
                {
                    using (IConnection conn = cf.CreateConnection())
                    {
                        using (IModel channel = conn.CreateModel())
                        {
                            var consumer = createConsumer(channel);
                            while (channel.IsOpen)
                            {
                                Thread.Sleep(10);
                                BasicDeliverEventArgs ea = null;
                                try
                                {
                                    ea = consumer.Queue.DequeueNoWait(null);
                                    if (ea == null) continue;
                                }

                                catch (Exception ex)
                                {
                                    TraceLogHelper.WriteError("RabbitMQ", "【里面】", ex.StackTrace);
                                    break;
                                }
                                var body = ea.Body;
                                var message = Encoding.UTF8.GetString(body);
                                var b = func(message);
                                if (b)
                                {
                                    channel.BasicAck(ea.DeliveryTag, false);
                                    Console.WriteLine("接收消息成功:" + message);
                                }

      
                            }
                        }
                    }
                    return true;
                }
                catch (Exception ex)
                {
                    TraceLogHelper.WriteError("RabbitMQ", "[外层]", ex.StackTrace);
                    return false;
                }
            };

　　

增加一个 Thread.Sleep(10);即可解决。

 

以后遇到无线循环的时候，需要加Sleep
