Spring Boot Microservices Project

Overview

This project demonstrates a microservices architecture using Spring Boot. It consists of the following core services:

• API Gateway: Handles routing of client requests to the appropriate microservice.
• Discovery Server: Service registry for dynamic discovery of microservices (typically using Eureka).
• Order Service: Manages order-related operations.
• User Service: Manages user-related operations.

Architecture

• Spring Boot is used for rapid application development.
• Eureka Discovery Server enables service registration and discovery.
• API Gateway (Spring Cloud Gateway or Zuul) routes requests to backend services.
• Each service is a separate Gradle project/module.

Project Structure

api-gateway/         # API Gateway service
order-service/       # Order management microservice
user-service/        # User management microservice
discovery-server/    # Eureka Discovery Server

Prerequisites

• Java 17 or later
• Gradle 7.x or later

Setup Instructions

1. Clone the repository

   git clone <your-repo-url>
   cd springboot-microservices

2. Build all services

   ./gradlew build

3. Run the Discovery Server first

   cd discovery-server
   ./gradlew bootRun

4. Run the API Gateway

   cd ../api-gateway
   ./gradlew bootRun

5. Run the Order and User Services

   cd ../order-service
   ./gradlew bootRun
   # In a new terminal:
   cd ../user-service
   ./gradlew bootRun

Usage

• Access the API Gateway at http://localhost:<gateway-port>
• Eureka dashboard is available at http://localhost:<eureka-port>/
• Update application.properties or application.yml in each service to configure ports and service names as needed.
