In the shared access policies section, click RootManageSharedAccessKey and copy the Primary Connection String. We will use this key to grant MassTransit permissions to access and manage resources on the Bus. We create a group of resources and a Service Bus type resource by selecting the Standard plan, essential to create topics and subscriptions.
Masstransit microservices install#
Note that for each transport you want to use, you will need to install the appropriate MassTransit Nuget package otherwise, you will not find the extension methods that allow you to build the bus instance. We need to configure the Masstransit middleware to specify the type of transport, settings, and endpoints.
Masstransit microservices code#
But that’s not all: what we’ve seen so far is the code that uses middleware to publish/consume messages is the code independent of the transport technology we use.
Masstransit microservices how to#
In the previous snippets, we have seen how to publish and consume a message with MassTransit. It will identify the consumer who can manage the message type, then the Consume method will be called. When a message is available in the queue to which the application is hooked, the MassTransit middleware will read the type in the metadata. Public async Task Consume(ConsumeContext context) This interface contains definitions of the methods needed to send messages through the bus. The instance of the bus will be injected into the constructor and is of type IBus. Our web app will be responsible for sending a message through our service bus. But you can find the complete code on my repository. In the article, you will find only the code related to MassTransit the code related to the UI will be omitted moreover, since the consumers will be almost similar, we will focus only on the code of the EmailSender. With MassTransit, we will create two consumers who can manage the type of message published by the web app. The services that will consume these messages will be two console applications: one will simulate sending emails, and the other sending SMS.
Then, it’s the task of the framework that routes the message through the transport infrastructure (Azure Service Bus, Amazon SQS, RabbitMq). The web application will send a message using MassTransit. Once created, we want to send emails and SMS notifications to the guests, but we want these operations not to impact the web app and instead are carried out by services created specifically for this type of task. In the example I present, we will have a web app implemented with Razor Pages, which will give the user the ability to create meetings. Transparent management of exceptions, retries and poisoned messages įor a complete list of features, take a look at this link.This framework offers us some important features, in addition to the basic features that each Service Bus should make available.
Masstransit microservices windows#
In particular, in the projects we worked on, we used it to integrate a web app with a windows service to manage some prolonged running operations without impacting the web application.
The client uses the Masstransit framework as an implementation of a Service Bus. If the processing fails, depending on the configuration of the error management policies, apply strategies to reprocess it. When a message is successfully managed, it reports to the broker that the message can be deleted. From the point of view of the application that manages the message, the Service Bus must be able to pick up the messages and trigger processes to handle them. When an application needs to send a message, it will do using a dedicated Service Bus method that, internally, will be responsible for routing it to one or more endpoints that can handle it. In the last year and a half, I have had the opportunity to work for a client with a strongly microservice-oriented architecture to support his system consisting of several applications and services that interoperate in an asynchronous way using a Service Bus.Ī Service Bus is an integration service that allows interoperability among heterogeneous components in a distributed system.
