How to inject dependency MassTransit Consumer in windsor container - dependency-injection

Question

How to use dependency injection in consumer class. I get error message as "The type 'Esb.Masstransit.RabbitMq.Application.IEventConsumerService' cannot be used as type parameter 'TConsumer' in the generic type or method 'MassTransit.ConsumerExtensions.Consumer(MassTransit.IReceiveEndpointConfigurator, System.Action<MassTransit.ConsumeConfigurators.IConsumerConfigurator>)'. There is no implicit reference conversion from 'Esb.Masstransit.RabbitMq.Application.IEventConsumerService' to 'MassTransit.IConsumer'"
This is container class
container.Register(Component.For<IEventConsumerService>().ImplementedBy<EventConsumerService>().LifestyleSingleton());
container.Register(Component.For<ICommandConsumerService>().ImplementedBy<CommandConsumerService>().LifestyleSingleton());
var busControl = Bus.Factory.CreateUsingRabbitMq(rabbit =>
{
var host = rabbit.Host(new Uri(rabbitMqHost), settings =>
{
settings.Password(rabbitMqUserName);
settings.Username(rabbitMqPassword);
});
rabbit.ReceiveEndpoint(host, eventQueue1, e =>
{
e.BindMessageExchanges = false;
e.Consumer<EventConsumerService>(); // I getting error here
e.Bind(typeof(IPublishMessage).FullName.Split('.').LastOrDefault(), x =>
{
x.RoutingKey = "1";
x.ExchangeType = ExchangeType.Direct;
});
});
});
container.Register(Component.For<IBus, IBusControl>().Instance(busControl));
This is Consumer class
public class EventConsumerService : BaseLogger, IEventConsumerService, IConsumer<IPublishMessage>
{
private readonly ICommandConsumerService _service;
public EventConsumerService(ICommandConsumerService service)
{
_service = service;
}
public Task Consume(ConsumeContext<IPublishMessage> context)
{
try
{
Console.WriteLine("In event consumer " + context.MessageId + " _" + context.Message.MessageId + ", " + context.Message.Message + " " + context.Message.CreationDate);
return Task.CompletedTask;
}
catch (Exception ex)
{
Logger.Error("EventConsumerService", ex);
}
return Task.CompletedTask;
}
}

You should use the container integration package, MassTransit.CastleWindsor and configure your container as shown in the documentation.
Also, consumers should be registered as concrete types, not interfaces.
Based upon your example:
var container = new WindsorContainer();
container.AddMassTransit(x =>
{
x.AddConsumer<EventConsumerService>();
x.UsingRabbitMq(cfg =>
{
cfg.Host(new Uri(rabbitMqHost), settings =>
{
settings.Password(rabbitMqUserName);
settings.Username(rabbitMqPassword);
});
cfg.ReceiveEndpoint(eventQueue1, ec =>
{
ec.ConfigureConsumeTopology = false;
ec.Bind(typeof(IPublishMessage).FullName.Split('.').LastOrDefault(), b =>
{
b.RoutingKey = "1";
b.ExchangeType = ExchangeType.Direct;
});
ec.ConfigureConsumer<EventConsumerService>(context);
});
});
});
Consumers should not be singleton, they should be scoped. The code above will register the consumer in the container for you.
