Spring Boot Microservices Project

A scalable food delivery system designed using Spring Boot microservices architecture, enabling seamless integration and performance.

🏗️ Architecture Overview

This project adopts a microservices-based architecture, ensuring modularity, fault isolation, and scalability.

🚀 Key Components

Backend Services

• API Gateway (Port: 8080) : Single entry point for requests, handling routing and load balancing.
• Eureka Service Discovery (Port: 8761) : Registers and discovers microservices for load balancing and monitoring.
• User Service (Port: 8081) : Manages user authentication, profiles, and JWT security.
• Restaurant Service (Port: 8082) : Handles restaurant data, menus, and image uploads.
• Order Service (Port: 8083) : Processes orders, integrates with users/restaurants, and tracks order statuses.
• Notification Service (Port: 8084) : Sends event-driven email notifications using Kafka.

Frontend

• Modern UI built with Angular 17.
• Features intuitive design and JWT-based authentication.

🛠️ Technologies Used

Backend

• Java 21, Spring Boot 3.3.4, Spring Cloud 2023.0.3
• Spring Security (JWT), MySQL, Kafka, OpenAPI (Swagger)

Frontend

• Angular 17, TypeScript, RxJS, TailwindCSS

DevOps & Tools

• Docker, Maven, Git

📋 Prerequisites

Before running the project, ensure the following are installed:

• Java 21, Node.js 18+, MySQL 8+, Kafka, Docker, Maven

🚀 Running Services Independently

Each microservice in this project can be run as a standalone Spring Boot application. Follow the steps below to run individual services.

1. Steps to Run an Individual Service:

1. Prerequisites:

   https://github.com/Vanhuyne/food-order-microservice.git
   cd food-order-microservice

2. Navigate to the Service Directory:

   Each service has its own directory. For example:

   cd user-service

3. Configure Application Properties

   • Open src/main/resources/application.properties or application.yml
   • Update database and service-specific configurations. Example for MySQL:

   spring.datasource.url=jdbc:mysql://localhost:3306/user_service_db
   spring.datasource.username=username
   spring.datasource.password=password

4. Build the Service

   Run the following command to package the service:

   mvn clean install

5. Set up the frontend

   cd frontend
   npm install
   npm start

2. Running with Docker: Build docker to use Kafka

docker-compose up -d
