RabbitMQ Application using Springboot
This document outlines the design and architecture of a RabbitMQ application built using Spring Boot. The purpose of this application is to demonstrate the basic functionality of a messaging system with RabbitMQ.
What is Rabbit MQ?
RabbitMQ is a message broker that originally implements the Advance Message Queuing Protocol (AMQP)
AMQP standardizes messaging using Producers, Broker and consumers.
AMQP standards was designed with the following main characteristics: Security, Reliability, Interoperability.
2. Architecture Overview
The application will consist of the following components:
· Producer: A Spring Boot application responsible for sending messages to the RabbitMQ exchange.
· RabbitMQ Server: A message broker used for storing and routing messages.
· Consumer: Another Spring Boot application responsible for receiving and processing messages from the RabbitMQ queue.
· Exchange: An exchange is a message router that routes messages to queues. There are four types of exchanges: direct, fanout, topic, and headers.
3. Component Details:
3.1 Producer:
The producer component will use the Spring Boot framework to create a RESTful endpoint for sending messages to RabbitMQ. Utilize the RabbitMQ Java client library to establish a connection to the RabbitMQ server. Publish messages to a RabbitMQ exchange using a predefined routing key.
3.2 RabbitMQ Server
RabbitMQ is a message broker that will:
Receive messages from the producer and route them to the appropriate queues.
Store and manage messages in queues.
Enable communication between the producer and consumer.
3.3 Consumer
The consumer component will:
Connect to the RabbitMQ server using the RabbitMQ Java client library.
Consume messages from a specific queue.
Process and handle the received messages.
4. Flow
The flow of the application is as follows:
The producer exposes a REST endpoint where clients can send messages.
Clients send HTTP requests to the producer’s endpoint.
The producer, upon receiving a request, formats the message and publishes it to a RabbitMQ exchange using a predefined routing key.
The RabbitMQ server receives the message and routes it to the specified queue.
The consumer, listening to the queue, consumes the message when it becomes available.
The consumer processes the message according to the application’s logic.
