Building Reactive Microservices with Spring WebFlux and Spring Boot

Modern web applications demand high concurrency and resilience under heavy load, which traditional blocking APIs struggle to deliver. Transitioning to a reactive paradigm allows you to build highly scalable, resource-efficient microservices that handle massive traffic with ease. This text-based course guides you through the core concepts of reactive programming, moving from foundational theory to practical implementation. You will understand how to write non-blocking code, design reactive RESTful APIs, and integrate reactive databases to build end-to-end responsive systems. What you'll learn: - Understand the core principles of reactive programming and the Reactive Streams specification. - Master Project Reactor fundamentals using key reactive types like Flux and Mono. - Build non-blocking REST APIs using annotated controllers in Spring WebFlux. - Implement reactive database access using R2DBC for fully non-blocking data pipelines. - Write robust unit and integration tests using WebTestClient and StepVerifier. - Apply reactive operators to transform, filter, and combine data streams efficiently. The course starts with fundamental concepts, comparing traditional blocking models with reactive execution, before guiding you through hands-on coding scenarios and database integration. You will learn by reading clear explanations and analyzing structured code snippets designed to build your practical skills. This course is designed for Java developers new to reactive programming, requiring only basic knowledge of Spring Boot and Java. No prior experience with reactive systems is needed.
