Course Project updated for latest Spring Boot 3.2.0

In this comprehensive course, you will dive into the world of Spring WebFlux and learn how to harness its power to build reactive and high-performance microservices. Spring WebFlux offers a non-blocking and event-driven approach that outperforms traditional Spring Web MVC. Through practical examples and hands-on exercises, you will gain the skills and knowledge to develop RESTful APIs, handle exceptions, work with query parameters, leverage functional endpoints, integrate with MongoDB using Spring Data Reactive, utilize Spring Data R2DBC for reactive relational databases, make non-blocking HTTP requests with WebClient, implement server-sent events for real-time updates, and handle blocking drivers/APIs seamlessly in your WebFlux applications.

By the end of this course, you will be equipped with the tools and techniques to build resilient and efficient microservices using Spring WebFlux.
