Asynchronous-RabbitMQ-Solution

A RabbitMQ-based messaging system designed for asynchronous communication in financial transaction processing. It ensures component decoupling, enhancing scalability and reliability. Well-suited for event-driven architectures, message queues, and distributed systems managing high transaction volumes efficiently.

Features

• Asynchronous Messaging: Handles background tasks without blocking other services.
• Message Queues: Efficient message distribution with RabbitMQ.
• Event-Driven Architecture: Supports event-driven systems, improving responsiveness.
• Scalable: Easily scales to handle high message volumes.
• Fault Tolerance: Ensures message delivery even in the event of service failures.

Modules

• Transaction Management: Module in charge of the logic of transfers, deposits, and withdrawals, ensuring idempotence and consistency through distributed transactions.
• Message Processing: Module that publishes and consumes events in RabbitMQ, configuring DLQ for failed messages.
• Security and Audit: Module that implements JWT for authentication and generates detailed financial audit reports.

Technologies Used

• Backend Framework: Spring Boot (Java)
• Message Broker: RabbitMQ
• JMS (Java Message Service): JMS for RabbitMQ message handling
• API Documentation: Swagger/OpenAPI
• Dependencies: Spring AMQP, RabbitMQ Client Library

Set Up the Environment

1. Install RabbitMQ:

   • Follow the installation guide from RabbitMQ official site.

2. Set up RabbitMQ:

   • Ensure RabbitMQ is running on the local or remote server:

     sudo systemctl start rabbitmq-server

3. Configure Environment Variables:

   • Create a .env file or set environment variables for RabbitMQ connection:

     RABBITMQ_HOST=localhost
     RABBITMQ_PORT=5672
     RABBITMQ_USERNAME=your_username
     RABBITMQ_PASSWORD=your_password

4. Add Dependencies to pom.xml:
   Add the following dependencies to your pom.xml to integrate RabbitMQ with Spring Boot:

   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-amqp</artifactId>
   </dependency>
   <dependency>
       <groupId>com.rabbitmq</groupId>
       <artifactId>amqp-client</artifactId>
       <version>5.9.0</version>
   </dependency>

5. Run the Application:

   • To start the Spring Boot application:

     mvn spring-boot:run

Usage

• Start the API server using Spring Boot:

  mvn spring-boot:run

• Access the API documentation at:

  http://localhost:8080/swagger-ui.html
