Rental BackEnd Challenge

This project is a comprehensive Backend designed for a car rental service. It includes a robust API for managing clients, reservations, accessory rentals, and vehicle groups. The system integrates with the Stripe payment gateway to facilitate secure online transactions. Additionally, it features a microservices architecture to handle email communication efficiently, using message queues to ensure reliability and scalability.

Technologies Used

• Spring Boot: Framework for developing Java applications.

• Spring AMQP (RabbitMQ): Integration with RabbitMQ for asynchronous email sending.

• JUnit 5: Unit and integration testing.

• Stripe API: Integration with the Stripe API for payment processing.

• SpringDoc OpenAPI: API documented with SpringDoc OpenAPI Swagger.

• NGINX: Web server and reverse proxy.

• Docker: Services use Docker containers for their lifecycle.

Main Features

• Authentication and Authorization: User authentication and role-based authorization (ADMIN, MANAGER, and USER).

• Reservation Management: Register and manage accessory reservations for individuals or vehicle groups.

• Person Management: Create, list, update, and delete information about individuals, including clients and employees.

• Accessory Management: Create, list, update, and delete accessories available for rental.

• Vehicle Group Management: Create, list, update, and delete vehicle groups.

• Stripe Integration: Allows users to pay for reservations using credit/debit cards through Stripe.

Email Sending Microservice

The system includes a microservice for sending emails, utilizing queues for asynchronous processing and ensuring email delivery. The microservice is responsible for:

• Asynchronous Email Sending: Sending emails asynchronously to avoid blocking during the execution of other tasks.

• Failure Handling: Robust and efficient handling of email sending failures.

• RabbitMQ Configuration: Using RabbitMQ for queue management and ensuring email delivery.

• Uses Cloud AMQP: Provides cloud-hosted messaging infrastructure, ensuring high availability, scalability, and performance for RabbitMQ queues.
