💻 Technologies

🏛️ Architecture

This project follows a Microservices Architecture:

• Product Service: Manages product details.
• Seller Service: Handles seller operations.
• Customer Service: Handles user data and customer operations.
• Order Service: Manages order details and processes transactions.

Each microservice has its own database schema and communicates with other services through REST APIs.

🛠 Setup

🛑 Prerequisites

• Java 11+
• Maven
• PostgreSQL
• Razorpay API key
• Docker (optional for containerization)

📦 Installation

1. Clone the repository: bash git clone https://github.com/Sucho6996/EcommerceBackend.git cd EcommerceBackend

2. Set up PostgreSQL:

   • Create a separate database for each microservice: product_db, seller_db, customer_db, order_db.
   • Update the application.properties file of each microservice with your PostgreSQL configurations.

3. Build and run each microservice: bash

   Product Service

   cd product-service mvn clean install mvn spring-boot:run

   Seller Service

   cd ../seller-service mvn clean install mvn spring-boot:run

   Customer Service

   cd ../customer-service mvn clean install mvn spring-boot:run

   Order Service

   cd ../order-service mvn clean install mvn spring-boot:run

🐳 Docker (Optional)

1. Build Docker images: bash docker build -t product-service ./product-service docker build -t seller-service ./seller-service docker build -t customer-service ./customer-service docker build -t order-service ./order-service

2. Run Docker containers: bash docker run -d -p 8081:8081 product-service docker run -d -p 8082:8082 seller-service docker run -d -p 8083:8083 customer-service docker run -d -p 8084:8084 order-service

🧑‍💻 Usage

Each microservice is accessible via different ports:

• Product Service: http://localhost:8081
• Seller Service: http://localhost:8082
• Customer Service: http://localhost:8083
• Order Service: http://localhost:8084
