Setup Instructions

1. Clone/Extract the Repository

cd e:\PBC Preparation\Backend\SpringBoot Project\E-Commerce-Microservice

2. Build All Services

From the root directory:

mvn clean install

Or build individual services:

cd "User Service" && mvn clean install
cd "Product Service" && mvn clean install
cd "Order Service" && mvn clean install

3. Configure Environment

Each service has an application.yml file in src/main/resources/. Review and update database connections, server ports, and other configurations as needed.

Running the Services

Option A: Using Docker Compose (Recommended)

docker-compose up -d

This starts all services and dependencies in containers.

Option B: Run Services Locally

Start each service in a separate terminal:

# Terminal 1 - User Service
cd "User Service"
mvn spring-boot:run

# Terminal 2 - Product Service
cd "Product Service"
mvn spring-boot:run

# Terminal 3 - Order Service
cd "Order Service"
mvn spring-boot:run
