Hands-On Spring Security 5 for Reactive Applications

By: Tomcy John

Overview of this book

Spring Security enables developers to seamlessly integrate authorization, authentication, and a range of security features for complex enterprise applications. This book provides a hands-on approach to developing reactive applications using Spring and will help you get up and running in no time. Complete with step-by-step explanations, practical examples, and self-assessment questions, the book begins by explaining the essential concepts of reactive programming, Spring Framework, and Spring Security. You’ll then learn about a variety of authentication mechanisms and how to integrate them easily with a Spring MVC application. You’ll also understand how to achieve authorization in a Spring WebFlux application using Spring Security. Furthermore, the book will take you through the configuration required to implement OAuth2 for securing REST APIs, and guide you in integrating security in microservices and serverless applications. Finally, you’ll be able to augment add-ons that will enhance any Spring Security module. By the end of the book, you’ll be equipped to integrate Spring Security into your Java enterprise applications proficiently.

Chapter 5. Integrating with Spring WebFlux

One of the new features introduced as a part of Spring Framework 5 is the introduction of a new reactive web application framework, Spring WebFlux. WebFlux lives alongside the well-established web application framework Spring MVC. The book aims to introduce reactive parts of Spring Security in which Spring WebFlux is one of the core components.

Making your application reactive brings in an asynchronous nature to your application. Traditional Java applications used threads to achieve parallel and asynchronous nature to the application, however, usage of threads for a web application is not scalable and efficient in any manner.

This chapter starts by introducing you to the core differences between Spring MVC and Spring WebFlux. It then delves into the Spring Security module and how reactive aspects have been brought into it.

In this chapter, we will cover the following topics:

  • Spring MVC versus WebFlux
  • Reactive support in Spring 5
  • Spring WebFlux
  • Spring WebFlux...
