Var globalPublicationTasks = Task.WhenAll(globalPublicationTasks) Īm i missing something? What am i doing wrong? I would expect that HandleAsync method is called when some integration event is published on the bus. Additionaly i append the code responsible for publishing my events: public async Task PublishAsync(params IIntegrationEvent events) But the problem is the HandleAsync method is never called, although some events are published. Public override async Task HandleAsync(IIntegrationEvent readyToBeSavedEvent = new _eventRepository.CreateAsync(readyToBeSavedEvent) Īwait _eventRepository.SaveChangesAsync() ĮventHandler base class implements the IConsumer interface, so i thought it should be somehow connected with all integration events occured on the bus. This means that you can publish an update and whoever is interested can get the new information. RabbitMQ can also be used to publish data even without knowing the subscribers. Today, I will implement RabbitMQ, so the microservices can exchange data while staying independent. Public EventHandler(IEventRepository eventRepository) In my last posts, I created two microservices using ASP. Private readonly IEventRepository _eventRepository Public abstract Task HandleAsync(TIntegrationEvent sealed class EventHandler : IntegrationEventHandler Public async Task Consume(ConsumeContext context) => IConsumer where TIntegrationEvent : class, IIntegrationEvent Here i attach the definition of EventHandler class, and it's parent: public abstract class IntegrationEventHandler : IIntegrationEventHandler, As you have noticed - i have only one consumer called "EventHandler" which has to handle all the IntegrationEvents. The connection parameters are correct, i've checked them few times. I've configured the communication in the event store like shown below: public static IServiceCollection RegisterMessagingDependencies(this IServiceCollection services, My event store has to handle all the integration events which are travelling across the bus. Back to the implementation - i have an event store (different container). The problem is any of my consumers don't respond to the corresponding message (probably due to some configuration errors). The messages from the service are published properly because i can notice them in RabbitMq Management System. It has no consumer due to our simplification - it only has to publish some message to the bus. Configure(configuration.GetSection(RabbitMQSettingsSectionKey)) AddSingleton(provider => provider.GetRequiredService()) HostConfigurator.Password(rabbitMQSettings.Password) Ĭonfigurator.ExchangeType = ExchangeType.Fanout good customer service skills an active listener good communication skills. HostConfigurator.Username(rabbitMQSettings.UserName) Recruiters, find in the CV database the CVs : Mass Transit and Ground. AddSingleton(serviceProvider => (configurator => Create a listener to listen for those messages. To register broker dependencies i use the following code: internal static IServiceCollection RegisterRabbitMQDependencies(this IServiceCollection services, After this tutorial you will be able to produce messages on a message Queue, listen for those messages and successfully configure a message queue. Let's simplify my solution, so imagine i have a simple common service which has to broadcast some messages to the bus. There are three main ways that you might want to send messages when using a message bus for asynchronous communication between systems in a distributed environment. I am new to messaging with RabbitMQ, and probably i've configured something improperly. I would like to attach some kind of event store to my solution. after the message is consumed.I am implementing application in microservices architecture. So, when a message isĬonsumed, you get event before the consumer is executed and Operation produces Start and Stop events using the Activity. You can subscribe to different types of diagnostic events produced by MassTransit.īelow is the list of names of MassTransit diagnostic sources. Public static async Task Main ( string args ) # Available diagnostic events
