Introduction to a Sample Microservice Project
Welcome to my sample microservice project, designed to provide a practical learning experience for junior developers. In this project, I explore the world of microservices, RabbitMQ for service communication, and key technologies like WebFlux, Actuator, and Spring Security.
What Is a Microservice?
A microservice is an architectural style where an application is composed of small, independently deployable services. Each service focuses on a specific business capability and communicates with other services via APIs, typically over HTTP.
Service Communication with RabbitMQ
In my project, I use RabbitMQ, a message broker, to facilitate communication between microservices. RabbitMQ enables asynchronous messaging, making it possible for services to communicate in a decoupled and scalable manner.
Key Technologies I Explore:
WebFlux: I leverage Spring WebFlux to build reactive microservices. Reactive programming allows me to handle a large number of concurrent connections efficiently.
Actuator: Spring Boot Actuator provides monitoring and management capabilities for my microservices. I gain insights into the health, metrics, and other crucial aspects of my services.
Spring Security: Security is a top priority. I demonstrate how to secure my microservices and APIs using Spring Security, ensuring data privacy and access control.
Why Learn from This Project?
This project is a valuable resource for junior developers for several reasons:
Hands-On Experience: I believe in learning by doing. You'll gain practical experience working with technologies commonly used in microservice architectures.
Real-World Scenario: The project mirrors real-world scenarios where multiple services collaborate to deliver a complete application.
Clean Code and Best Practices: My project adheres to clean code principles and best practices, demonstrating how to write maintainable and efficient microservices.
Inter-Service Communication: Understanding how services communicate is a fundamental concept in microservices. You'll see this in action through RabbitMQ.
Security and Monitoring: I address security concerns and the importance of monitoring services to ensure reliability.

########################################################################################## Access Actuator Endpoints: You can access Actuator endpoints via HTTP requests. For example:
Health Endpoint: http://localhost:9090/actuator/health
Info Endpoint: http://localhost:9090/actuator/info
Metrics Endpoint: http://localhost:9090/actuator/metrics
