Introduction

This project is a capstone e-commerce application built with Spring Boot (version 3.2.*) following a microservices architecture. The system is divided into three core services: User Service, E-commerce Service, and discovery-server Service. Communication between microservices is handled using FeignClient.

Problem Statement

The primary objective of this project was to design and develop an e-commerce platform utilizing a microservices architecture. The key services implemented include a User Service for authentication and role-based access, an E-commerce Service for product and order management, and a Eureka Service for service discovery.

Features

• Registration and Authentication: Users can register, log in, and manage their profiles.
• Role-Based Access Control: Users have different roles and permissions based on their privileges (e.g., Admin, Customer).
• Profile Management: Users can update personal information.

E-commerce Service

• Product Management: Handle product catalogs and categories.
• Cart Functionality: Users can add/remove items to/from their cart.
• Order Processing: Facilitates order placement and fulfillment i.e checkout, cancel.

Eureka Service

• Service Discovery: Automates microservices registration and discovery, ensuring seamless interaction between different services.
