Overview of this book

Spring 5.0 is due to arrive with a myriad of new and exciting features that will change the way we’ve used the framework so far. This book will show you this evolution—from solving the problems of testable applications to building distributed applications on the cloud. The book begins with an insight into the new features in Spring 5.0 and shows you how to build an application using Spring MVC. You will realize how application architectures have evolved from monoliths to those built around microservices. You will then get a thorough understanding of how to build and extend microservices using Spring Boot. You will also understand how to build and deploy Cloud-Native microservices with Spring Cloud. The advanced features of Spring Boot will be illustrated through powerful examples. We will be introduced to a JVM language that’s quickly gaining popularity - Kotlin. Also, we will discuss how to set up a Kotlin project in Eclipse. By the end of the book, you will be equipped with the knowledge and best practices required to develop microservices with the Spring Framework.

Preface

Chapter 11. Reactive Programming

In the previous chapter, we discussed implementing typical data flow use cases with microservices using Spring cloud data flow.

Functional Programming marks a shift from traditional imperatives to a more declarative style of programming. Reactive programming builds on top of functional programming to provide an alternative style.

In this chapter, we will discuss the basics of reactive programming.

The microservice architecture promotes message-based communication. One important tenet of reactive programming is building applications around events (or messages). Some of the important questions we need to answer include the following:

  • What is reactive programming?
  • What are the typical use cases?
  • What kind of support does Java provide for it?
  • What are the reactive features in Spring WebFlux?
