Implement messaging using RabbitMQ with Spring Boot ApplicationĬreate a Maven, Spring Boot Project in any of your favorite IDE. RabbitMQ is accessible by default over port 15672 once setup is complete and RabbitMQ is running.

You can follow directions from the official RabbitMQ website to install RabbitMQ as per your operating system. You can refer to this blog post to run RabbitMQ on your machine via Docker. There are two common ways to set up RabbitMQ on your local machine.

To begin with the RabbitMQ integration with the Spring Boot Application, the primary step is to download and install RabbitMQ on your local machine. Asynchronous Messaging: Messaging queues are the best way to implement asynchronous programming.Background Jobs: Sending background messages, emails, or notifications to loads of users.

For example, calculations, searching or pdf creation, etc. High Response Time: When the response time of a request is too much.Decoupling: We need a way to decouple communication between different services or applications.There are many use-cases of Messaging Queue such as: As a result, neither frontline workers nor kitchen employees are dependent on one another instead, they are aware of their roles and continue to work as independent entities. Similarly, the kitchen crew receives increased orders for drink preparation. However, the delivery of order happens in order. Rather, he continues to work and entertain other customers. While the kitchen crew prepares your food, the front-line employee does not sit around waiting for your order. The kitchen crew received your order and began preparing it. The order is sent to the kitchen, where your drink will be prepared. When you enter the coffee shop, the front desk worker greets you, takes your order, and gives you an order number. Take, for example, a messaging queue application at a coffee shop to demonstrate the use-case. In real life, we frequently deal with the application of messaging queues. Common Use-Cases of using Messaging Queue: Consumer: A consumer is a user program that is responsible to receive messages.

It has certain limitations like disk space and memory.

Queue: A queue is a mailbox or a buffer that stores messages.

Whereas, the R outing K ey is the address that the exchange uses to determine which queue the message should be sent to. Binding is the link between a queue and the exchange.

Exchange: Exchanges are message routing agents, it is responsible to route the messages to different queues with the help of header attributes, bindings, and routing keys.

Producer: A producer is a user program that is responsible to send or produce messages.

The data can hold requests, information, meta-data, etc.

Message: A message is a form of data that is shared from the producer to the consumer.

Key-Components in Messaging via RabbitMQ:īelow is the image that depicts the workflow and key components involved in the messaging via RabbitMQ. It is important to note that communication is Asynchronous in the messaging queue, which means the sender and receiver do not need to interact with the message at the same time.

RabbitMQ receives, stores, and forwards the data or messages. Similarly, in the world of Softwares communication works the same way.Ĭonsider an analogy of a mailbox where you send your letter or email to the recipient via mail service and you are assured that it will be received. In the latter case, we do not wait until the response arrives and therefore we can continue our own work, as we are not dependent on the response. Why do we need a Messaging Queue?Ĭommunication is a two-way process we may receive an immediate response, but we may also receive a response after some time. Various programming languages provide support for RabbitMQ. It’s a popular AMQP (Advanced Message Queuing Protocol)broker. RabbitMQ is an open-source message broker that allows enterprise applications to communicate with each other. So, let’s begin learning! What is a RabbitMQ?

We will also walk through a step-by-step guide to implement messaging using RabbitMQ in a Spring Boot Application and will see how to publish and consume messages in a queue using RabbitMQ. In this article, we will learn about RabbitMQ and explore its common use-cases.
