同一消息的多个订阅者重新连接Azure服务总线

Question

我有两个完全相同的消费者

消费者1

using (var adapter = new BuiltinHandlerActivator())
        {
            adapter.Handle<string>(async (bus, message) =>
            {
                Console.WriteLine("Got message > " + message);

                await bus.Reply("Received in consumer 1");
            });

            Configure.With(adapter)
                .Transport(t => t.UseAzureServiceBus(connectionString, "server"))
                .Start();

            adapter.Bus.Subscribe<string>().Wait();

            Console.WriteLine("Press ENTER to quit");
            Console.ReadLine();
        }

消费者2

using (var adapter = new BuiltinHandlerActivator())
        {
            adapter.Handle<string>(async (bus, message) =>
            {
                Console.WriteLine("Got message > " + message);

                await bus.Reply("Received in Consumer 2");
            });

            Configure.With(adapter)
                .Transport(t => t.UseAzureServiceBus(connectionString, "server"))
                .Start();

            adapter.Bus.Subscribe<string>().Wait();

            Console.WriteLine("Press ENTER to quit");
            Console.ReadLine();
        }

制作人

using (var adapter = new BuiltinHandlerActivator())
        {
            adapter.Handle<string>(async message =>
            {
                Console.WriteLine("Returned > " + message);
            });

            var bus = Configure
                .With(adapter)
                .Transport(t => t.UseAzureServiceBus(connectionString, "client"))
                .Routing(r => r.TypeBased().Map<string>("server"))
                .Start();

            Console.WriteLine("Press Q to quit or any other key to produce a job");
            while (true)
            {
                Console.Write("Write something > ");
                var text = Console.ReadLine();

                if (string.IsNullOrWhiteSpace(text)) break;

                bus.Publish(text).Wait();
            }
        }

我期望的是，每当我从生产者发送消息时，我的两个消费者都将显示该消息。现在，仅在其中之一中执行此操作。当我关闭该邮件并发送另一封邮件时，剩下的一封邮件会收到。

[基本上，您只需要给使用者一个不同的名字。 Rebus为每个生产者创建一个主题（基于程序集，名称空间，类型），并在这些主题中为每个消费者创建订阅。如果两个使用者使用相同的名称，他们将争夺消息。

                .Transport(t => t.UseAzureServiceBus(connectionString, "consumer1"))
                .Transport(t => t.UseAzureServiceBus(connectionString, "consumer2"))
