Hands-On Reactive Programming in Spring 5

By: Oleh Dokuka, Igor Lozynskyi

Overview of this book

These days, businesses need a new type of system that can remain responsive at all times. This is achievable with reactive programming; however, the development of these kinds of systems is a complex task, requiring a deep understanding of the domain. In order to develop highly responsive systems, the developers of the Spring Framework came up with Project Reactor. Hands-On Reactive Programming in Spring 5 begins with the fundamentals of Spring Reactive programming. You’ll explore the endless possibilities of building efficient reactive systems with the Spring 5 Framework along with other tools such as WebFlux and Spring Boot. Further on, you’ll study reactive programming techniques and apply them to databases and cross-server communication. You will advance your skills in scaling up Spring Cloud Streams and run independent, high-performant reactive microservices. By the end of the book, you will be able to put your skills to use and get on board with the reactive revolution in Spring 5.1!

Transfiguration of the Reactive Landscape

The fact that JDK 9 includes the Reactive Streams specification enforces its significance, and it has started to change the industry. The leaders in the Open Source Software industry (such as Netflix, Red Hat, Lightbend, MongoDB, Amazon, and others) have started adopting this excellent solution in their products.

RxJava transfiguration

In this way, RxJava provides an additional module that allows us to easily convert one reactive type into another. Let's look at how to convert Observable<T> to Publisher<T> and adopt rx.Subscriber<T> to org.reactivestreams.Subscriber<T>.

Suppose we have an application that uses RxJava 1.x and Observable as the...
