View the documentation - PDF View postman documentation

Overview

Electronic_Store is a comprehensive online electronics store application built with Java, Spring Boot, Hibernate, and MySQL. The application provides a full set of web services to manage users, categories, products, carts, and orders, each with well-defined JPA relationships, enabling nested API responses. The project is designed to be scalable, maintainable, and user-friendly, with a focus on clean code architecture.

Features

Modules

  • User
  • Category
  • Product
  • Cart
  • Order

Each module is interconnected through JPA relationships, allowing for complex nested API responses.

API Capabilities

  • Pagination and Sorting: Customize API responses with pagination and sorting.
  • Nested API Responses: Access comprehensive data structures due to well-defined JPA relationships.
  • Standard API Format: APIs follow a consistent, easy-to-remember format.

Request Validation

Integrated request validation ensures that all user inputs are checked before processing, reducing errors and maintaining data integrity.

Exception Handling

Global exception handling is implemented to provide formatted error responses with clear messages, helping users understand and resolve issues efficiently.

Logging

Robust logging mechanisms are in place to trace and resolve issues by capturing detailed logs during API execution.

Image Handling

Supports image management for users, categories, and products, enhancing the application’s functionality with visual content.

Architecture

The project follows a three-layered architecture:

  1. Controller Layer: Handles HTTP requests and responses.
  2. Service Layer: Contains business logic.
  3. Repository Layer: Manages data persistence and retrieval.

Database Persistence

Real-time data is securely stored in a MySQL database, ensuring data integrity and availability for future use.

Technologies Used

  • Java: The core programming language used for its object-oriented features and platform independence, allowing for robust application development.
  • Spring & Spring Boot: Provides a powerful framework and rapid application development environment for creating enterprise-grade web applications with dependency injection and various tools to manage the application's life cycle.
  • JPA (Java Persistence API): Used for its ability to map Java objects to relational database tables, facilitating easier database operations and management.
  • Hibernate: Implements JPA, providing advanced ORM capabilities to efficiently manage data persistence, lazy loading, and transaction handling.
  • MySQL Database: Chosen for its reliability, performance, and scalability in managing relational data, ensuring data is persistently and securely stored.

Summary

Electronic_Store is a well-structured, feature-rich web application offering a seamless user experience through advanced API features, image handling, and robust error management. The use of a standard API format, a three-layered architecture, and effective logging ensures that the system is maintainable, scalable, and easy to use.
