Microservices Project

This project demonstrates the implementation of microservices architecture using Spring Boot, Spring Cloud, Eureka for service discovery, and Feign for service communication. The project consists of four microservices: Quiz, Question, ApiGateway, and ServiceRegistry. Separate databases are used for the Question and Quiz services.

Microservices Overview

• Quiz Service: Manages quiz-related operations.
• Question Service: Handles questions and answers.
• ApiGateway: Routes requests and acts as the entry point for communication.
• ServiceRegistry: Registers and discovers microservices.

Prerequisites

• Java 17
• Gradle
• Docker (optional for database containers)

Getting Started

Follow these steps to build and run the microservices:

1. Build the Projects

cd quiz-service
./gradlew clean build

cd ../question-service
./gradlew clean build

cd ../api-gateway
./gradlew clean build

cd ../service-registry
./gradlew clean build

Run the Services

Start the Service Registry:

cd service-registry
./gradlew bootRun

cd ../quiz-service
./gradlew bootRun

cd ../question-service
./gradlew bootRun

cd ../api-gateway
./gradlew bootRun

Microservices Details

1. Quiz Service

• Endpoint: /quiz/**
• Description: Manages quiz-related operations.

2. Question Service

• Endpoint: /question/**
• Description: Handles questions and answers.

3. ApiGateway

• Endpoint: /8765
• Description: Routes requests and serves as the entry point.

4. Service Registry

• Endpoint: [/eureka](http://localhost:8761/)
• Description: Registers and discovers microservices.

Service Communication

The services communicate with each other using the Eureka service registry and Feign for client-side load balancing. The ApiGateway routes requests to the appropriate microservices based on the specified paths.
