Microservices Architecture for User and Notification Management

This repository contains a microservices-based project that demonstrates the implementation of a User Service and a Notification Service using Spring Boot, Eureka Discovery Server, and MongoDB/PostgreSQL. The system leverages Feign Clients for inter-service communication and integrates with Eureka Server for service registration and discovery.

Features

1. User Service

• Handles user management operations.
• Supports user creation, retrieval, and persistence in a PostgreSQL database.
• Communicates with the Notification Service to send user-specific notifications.

2. Notification Service

• Manages notifications for users.
• Stores notification data in a MongoDB collection.
• Provides APIs for saving and retrieving notifications.

3. Eureka Discovery Server

• Centralized service registry for dynamic service discovery.
• Enables load balancing and fault tolerance.

4. Inter-Service Communication

• Uses Spring Cloud OpenFeign for declarative REST client communication.
• Supports service discovery and load balancing through Eureka.

5. Database Configuration

• User Service: PostgreSQL with Hibernate for ORM.
• Notification Service: MongoDB with Spring Data MongoDB for NoSQL database operations.

Technologies Used

• Spring Boot for microservices.
• Spring Cloud for service discovery and Feign integration.
• MongoDB and PostgreSQL as databases.
• Docker for containerization.
