E-commerce Web Application

E-commerce Web Application – Java Project

The E-commerce Web Application, also known as SmartShop, is a complete full-stack Java web application developed for online shopping. The project is built using JSP, Servlets, Spring MVC, Spring AOP, JDBC, MySQL, Maven, and Apache Tomcat.

The application follows a clean MVC architecture and a three-tier design consisting of presentation, business, and data access layers. It provides a complete customer shopping workflow along with a powerful administrator panel for managing products, categories, stock, pricing, and customer orders.

Project Overview

SmartShop demonstrates the practical implementation of a real-world e-commerce workflow using Java web technologies. Customers can register and log in, browse products by category, search for products, add products to the shopping cart, update cart quantities, place orders, and view their order history.

The administrator panel provides role-based access for managing product categories, products, product images, stock, pricing, and customer orders. Administrators can also update order statuses such as Placed, Shipped, and Delivered.

Customer Module

• Secure customer registration and login
• Hashed user passwords
• Browse products by category
• Search products by name or keyword
• Add products to shopping cart
• Update cart quantities
• Remove products from cart
• Place orders with shipping details
• View complete order history

Admin Module

• Secure administrator login
• Role-based access control
• Add, update, and delete product categories
• Add, update, and delete products
• Upload product images
• Manage product stock
• Manage product pricing
• View customer orders
• Update order status

Shopping Cart

The shopping cart allows customers to add products before placing an order. Customers can update the quantity of cart items or remove products from the cart before proceeding with checkout.

Order Management

The order management functionality allows customers to place orders with shipping details and view their complete order history. Administrators can view customer orders and update their status between Placed, Shipped, and Delivered.

Product Management

Administrators can manage the product catalog by creating, updating, and deleting product categories and products. Product information includes pricing, stock, and image paths.

Search and Category Browsing

Customers can browse products according to categories and search for products using their name or keyword. This provides a convenient way to find products within the online store.

Technology Stack

• Programming Language: Java
• Frontend: JSP, HTML5, CSS3, Bootstrap
• Backend: Java, Servlets, Spring MVC
• AOP: Spring AOP for logging and performance monitoring
• Database: MySQL
• Database Access: JDBC
• Build Tool: Maven
• Server: Apache Tomcat
• IDE: Eclipse / IntelliJ IDEA

Architecture

The application follows an MVC and three-tier architecture. JSP handles the presentation layer, while Servlets and Spring MVC controllers handle HTTP requests. The application separates presentation, business logic, and data access to provide a clean and organized project structure.

Database Design

The project uses a normalized MySQL database with relationships defined using primary and foreign keys. The main database tables include:

• users: Customer and administrator account details
• categories: Product category information
• products: Product details, price, stock, and image path
• cart: Shopping cart items associated with users
• orders: Order information, status, and totals
• order_items: Individual products included in orders

Spring AOP

Spring AOP is used in the project for cross-cutting concerns such as logging and performance monitoring. This demonstrates the use of aspect-oriented programming within a Java Spring MVC application.
