POMassTransit Subscriptions and Receiving Own Messages
text
Body
copied!<p>I am trying to implement a proof of concept service bus using MassTransit. I have three applications which need to communicate changes of a common entity type between each other. So when the user updates the entity in one application, the other two are notified.</p> <p>Each application is configured as follows with their own queue:</p> <pre><code>bus = ServiceBusFactory.New(sbc => { sbc.UseMsmq(); sbc.VerifyMsmqConfiguration(); sbc.ReceiveFrom("msmq://localhost/app1_queue"); sbc.UseSubscriptionService("msmq://localhost/subscription"); sbc.UseControlBus(); sbc.Subscribe(subs => { subs.Handler<IMessage1>(IMessage1_Received); }); }); </code></pre> <p>There is also a subscription service application configured as follows:</p> <pre><code>subscriptionBus = ServiceBusFactory.New(sbc => { sbc.UseMsmq(); sbc.VerifyMsmqConfiguration(); sbc.ReceiveFrom("msmq://localhost/subscription"); }); var subscriptionSagas = new InMemorySagaRepository<SubscriptionSaga>(); var subscriptionClientSagas = new InMemorySagaRepository<SubscriptionClientSaga>(); subscriptionService = new SubscriptionService(subscriptionBus, subscriptionSagas, subscriptionClientSagas); subscriptionService.Start(); </code></pre> <p>The problem is that when one of the applications publishes a message, all three applications receive it (including the original sender).</p> <p>Is there any way to avoid this (without resorting to adding the application name to the message)?</p> <p>Thanks,</p> <p>G</p>
