消息不会在masstransit中到达订阅者

Question

我有两个项目在不同的进程中运行,RMQ部署在一台单独的机器上.

这是我的发布商代码

Bus.Initialize(config =>
            {
                config.UseRabbitMq();
                config.UseRabbitMqRouting();
                config.UseControlBus();
                config.EnableMessageTracing();
                config.EnableRemoteIntrospection();
                config.ReceiveFrom("rabbitmq://debug:debug@data.sampleserver.com:5672/bus/response-queue");
            });

            Console.ReadLine();

            int i = 0;

            while (i < 20)
            {
                i += 1;

                Console.WriteLine("Publishing...");
                Bus.Instance.Publish(new Message
                    {
                        Body = String.Format("Body = {0}", i)
                    });

                Console.ReadLine();
            }

            Console.ReadLine();

这是我的订阅者代码:

Bus.Initialize(config =>
            {
                config.UseRabbitMq();
                config.UseRabbitMqRouting();
                config.ReceiveFrom("rabbitmq://debug:debug@data.sampleserver.com:5672/bus/response-queue");
                config.UseControlBus();
                config.EnableMessageTracing();
                config.UseHealthMonitoring(10);
            });

            var service = HostFactory.New(config =>
            {
                config.SetServiceName("survey");
                config.SetDisplayName("survey");
                config.SetDescription("Survey service");

                config.Service<Service>(s =>
                {
                    s.ConstructUsing(sv => new Service(Bus.Instance));
                    s.WhenStarted(sv => sv.Start());
                    s.WhenStopped(sv => sv.Stop());
                });
            });

            Task.Factory.StartNew(() =>
            {
                try
                {
                    service.Run();
                }
                catch (Exception e)
                {
                    Console.WriteLine(e);
                }
            });

在服务器中,我有以下订阅:

public Service(IServiceBus serviceBus)
        {
            _serviceBus = serviceBus;
            _serviceBus.SubscribeHandler<Message>(Handle);
        }

        void Handle(Message message)
        {
            Console.WriteLine("Receive a new message with body {0}", message.Body);
        }

当我通过发布者发送一组消息时,只有少数消息成功到达订阅者.其中大多数属于响应队列错误.

我是masstransit的新手,我不明白里面发生了什么,也不明白我怎么弄明白.

你能在这种情况下推荐什么？

Answer 1

我注意到您示例中的发布者和订阅者正在侦听同一队列.通常,您应该将每个端点放在单独的队列中.MassTransit将根据类型处理消息路由.
