🍃 Spring Microservices

This project demonstrates a microservices architecture with the following components:

• api-gateway: Central entry point using Spring Cloud and Redis, supports dynamic routing, load balancing and rate limiting
• eureka-server: Service registry and discovery using Netflix Eureka
• organization-service: Manages organizations, exposes REST endpoints, and is called via FeignClient
• event-service: Manages events, communicates asynchronously via RabbitMQ
• news-service: Consumes event messages and exposes a GraphQL API for querying news

🛠 Prerequisites

• Java 17+
• Docker & Docker Compose

🚀 How to run

1. Clone this repo

git clone git@github.com:seraaaaaaaa/spring-microservices.git
cd spring-microservices

2. Build JARs using the provided script:

• On Windows: build.bat

• On Linux/macOS: build.sh

3. Start all services using Docker Compose:

docker-compose up --build

4. Access the services:

Service	URL
API Gateway	http://localhost:8080
Eureka Dashboard	http://localhost:8761
RabbitMQ UI	http://localhost:15672

🔁 Flow Overview

1. All services register themselves with Eureka.

2. The event-service uses FeignClient to communicate with the organization-service by service name.

3. When an event is created, a message is sent to RabbitMQ.

4. The news-service listens for incoming messages and creates a related news entry.

5. External requests go through the API Gateway, which manages routing, load balancing, and rate limiting with Redis.
