This repository serves as a starting point for working with microservices. Currently, it features three services: Barber, Recommendation, Notification which interact with each other.
Apart from these, there's also an Eureka Server managing requests between instances.
Spring OpenFeign is used, making it easy to create REST clients by defining interfaces and eliminating boilerplate code.
Furthermore, a Notification service is implemented to store all requests made to other instances. Tracking has also been implemented.
Each of the three services (Barber, Recommendation, and Notification) is connected to its respective PostgreSQL, MySQL and MongoDB databases.
This project is an excellent starting point for developing microservices applications.
The application is built using Spring Boot 3.1.2 version and the following frameworks and technologies:
- Spring: Boot, Cloud, Framework, Data
- Hibernate
- Maven
- PostgreSQL, MySQL, MongoDB
- RabbitMQ
- Tracing with observing tool Zipkin (runs on
localhost:9411) - Docker
- Lombok
- Spring Cloud Gateway - Load Balancer on port 8083
- Kubernetes - branch without EurekaServer and Spring Cloud Gateway
To launch the application, execute docker compose up -d.
To test the functionality, perform a POST request on the Load Balancer endpoint at localhost:8083/api/v1/barbers using the following request body:
{
"firstName": "Name",
"lastName": "LastName",
"company": "BarberDream",
"email": "barber@gmail.com"
}Before performing request check availibility of all services - http://localhost:8761/
You can also track the request - http://localhost:9411/
Future enhancements include introducing Kafka/RabbitMQ ✅ queues and other improvements.
Deployment to AWS using Kubernetes is on the roadmap, and the project is continuously evolving.
