DigiMarket Microservices Backend

DigiMarket is a microservices-based e-commerce platform built using Spring Boot. It includes various services such as customer management, product catalog, order processing, payment handling, and more. The project uses a range of technologies to provide a robust and scalable solution.

Microservices

1. API Gateway: Central entry point for the system.
2. Configuration Server: Centralized configuration management using Spring Cloud Config.
3. Customer Service: Manages customer-related operations.
4. Discovery Server: Service registry and discovery using Eureka.
5. Notification Service: Handles notifications to users.
6. Order Service: Manages order processing.
7. Payment Service: Handles payment transactions.
8. Product Service: Manages the product catalog.

Installation and Setup

1. Install Required Software:

   • Download and install Java JDK, IntelliJ IDEA, Apache Kafka, MySQL, MongoDB, Zipkin, Keycloak (optional), Docker from the links provided above.

2. Database Setup:

   • Start MySQL and MongoDB services.
   • Create databases as needed and configure connections in each microservice.

3. Start Required Services:

   • Start Apache Kafka.
   • Start Zipkin for distributed tracing.
   • (Optional) Start Keycloak for identity and access management.

4. Microservice Setup:

   • Clone the DigiMarket repository.
