Introduction

This system is desing keeping customers and mostly administrators in mind, to have an effective reservation system. The Shopping Cart Reservation System aims to address this need by offering a seamless experience for users looking to reserve products and for administrators managing the reservation process.

I developed a Shopping Cart Reservation System using Java 17, Spring Boot, MySQL, Maven, Spring Data JPA, and JWT authentication. The main purpose of this project was to allow users to add products to a cart, reserve items, update cart items, delete items, and finally place an order.

I created REST APIs for user signup, cart creation, fetching carts by cart ID or username, adding products to a cart, deleting products from a cart, placing orders, and deleting carts.

For database operations, I used Spring Data JPA with MySQL. For security, I implemented login authentication using JWT token, so only authenticated users can access protected APIs.

The main entities were User, Cart, CartItem, Product, and Order. The cart maintained the selected products and their reservation status, so admins or users could track whether a product was reserved, updated, deleted, or ordered.

This project helped me understand how to design CRUD APIs, manage relationships between entities, handle authentication, and build a backend flow similar to an e-commerce cart system.

Features

• CRUD Operations: Create, Read, Update, and Delete operations for managing product reservations.
• Login Authentication: An intuitive authentication system which provide JWT token for better security.
• Reservation Management: Efficient handling of product reservations with clear status tracking.
