![]() To setup logging there is another method we can use on the HostBuilder. Loggingįinally, there is one more cross-cutting concern for which we can use the generic host to do setup: logging. Now we can set the connection string to RabbitMq inside our appsettings.json, and possibly override its value for a particular environment by adding an for example. Var host = cfg.Host( new Uri(configuration.GetConnectionString( "RabbitMq")), h => Var configuration = serviceProvider.GetRequiredService() ConfigureAppConfiguration((hostContext, config) =>Ĭonfig.SetBasePath(Environment.CurrentDirectory) Ĭonfig.AddJsonFile( "appsettings.json", optional: false) Ĭonfig.AddJsonFile( $"appsettings.json", optional: true) To setup configuration we can use ConfigureHostConfiguration and ConfigureAppConfiguration. So far we’ve only used the dependency injection features of the generic host. When we shut down the host with Control-C, the generic host will automatically call StopAsync on our hosted service, which again will call StopAsync on the IBusControl instance which will do some clean up. By doing this, the generic host will automatically run StartAsync on our hosted service, which in turn will call StartAsync on the IBusControl instance, essentially opening the connection to RabbitMq and starts listening for messages. Next, we add our MassTransitHostedService as a scoped service to the DI container as well. Starting with RabbitMQ 3.7.0, the format is in the sysctl format. In this case we’re adding IBusControl as a singleton and use MassTransit’s RabbitMq transport as the implementation. The Main Configuration File, nf The configuration file nf allows the RabbitMQ server and plugins to be configured. Note that we’re using the ConfigureServices() method on the HostBuilder to add additional services to the dependency injection container. Var host = cfg.Host( new Uri( "rabbitmq://localhost"), h => ConfigureServices((hostContext, services) => Public static async Task Main( string args) AddInfrastructureServices(Configuration) // MassTransit-RabbitMQ Configuration services. We registered the consumer by loading executing assembly and giving it to the AddConsumers()method. #Masstransit app.config rabbitmq port how to#So let’s create a new console application: For more information on how to configure your application. Now, we are going to set up Program.cs in order to connect app with RabbitMQ via MassTransit. For example a background processing service that reads messages from a queue and processes them. For any servers that want to use the message queue, only 5672 is required. For a cluster of nodes, they must be open to each other on 35197, 43. Creating a console hostĪ typical example of where the hosting API would be useful is in a console application that just needs to keep running until someone stops it. RabbitMQ Management console: PORT 15672 for RabbitMQ version 3.x. It is currently planned for the 2.1 release and although there is no preview available for that version, we can still try it out which is what I’ve done lately and I’ll go over it in this post. You can read more about the reasoning behind it in this GitHub issue. In fact, the ASP.NET team has seen this as well and decided to further abstract the WebHostBuilder into a more generic HostBuilder API. If we look at that list, there are a few things that are very specific to web applications, but there are also a number of things that are desirable for any type of application.
