Fully Completed Microservices Project

Overview

This repository contains a collection of fully completed microservices built with Spring Boot version 3.2.5 and Java 17. The project utilizes Spring Cloud version 2023.0.1 for implementing various distributed system patterns and features.

Microservices Description

1. Config Server
   • Provides centralized configuration for all microservices.
   • Uses Spring Cloud Config Server.
2. Customer Service
   • Manages customer data and operations.
   • Integrated with Eureka Discovery.
3. Discovery Service
   • Service registry using Netflix Eureka.
   • Enables service discovery for other microservices.
4. Gateway Service
   • API Gateway for routing requests to appropriate microservices.
   • Uses Spring Cloud Gateway.
   • Includes distributed tracing and circuit breaker.
5. Notification Service
   • Handles notifications and alerts.
   • Uses Kafka for messaging.
6. Order Service
   • Manages orders and their statuses.
   • Integrated with Eureka Discovery.
7. Payment Service
   • Processes payments.
   • Uses Eureka Discovery and Zipkin for tracing.
8. Product Service
   • Manages product information.
   • Integrated with Eureka Discovery.

Features

• Service Discovery: All microservices register with the Eureka server for easy discovery.
• Centralized Configuration: Configurations are managed centrally using the Spring Cloud Config Server.
• API Gateway: Spring Cloud Gateway is used for routing and handling cross-cutting concerns like security, monitoring, and resilience.
• Distributed Tracing: Zipkin is used for tracing requests across microservices.
• Circuit Breaker: Circuit breaking capabilities provided by Spring Cloud Circuit Breaker.
• Messaging: Kafka is used for asynchronous communication between microservices.

Prerequisites

• Java 17 or later
• Maven or Gradle
• Docker (optional, for containerized deployment)

Running the Microservices

1. Clone the repository

   git clone https://github.com/PramithaMJ/fully-completed-microservices.git
   cd fully-completed-microservices
   

2. Start Config Server

   cd config-server
   mvn spring-boot:run
   

3. Start Discovery Service

   cd discovery
   mvn spring-boot:run
   

4. Start Other Microservices Start the remaining microservices in any order. Ensure they are configured to register with the Discovery Service.

   cd <microservice-name>
   mvn spring-boot:run
   

Configuration

Each microservice has its configuration properties defined in the application.yml or application.properties file. The Config Server properties should be specified in a central configuration repository.

Deployment

To deploy the microservices using Docker, use the Dockerfile available in each microservice directory. You can build and run the Docker images as follows:

cd <microservice-name>
docker build -t <microservice-name>:latest .
docker run -d -p <port>:<container-port> <microservice-name>:latest
