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.

In this chapter, we introduced you to new application requirements and then moved to some of the core reactive concepts. We looked at the Reactive Manifesto and reactive programming. We then moved our attention to Spring 5 and Spring Security 5, and touched on some of the new features in it, especially regarding reactive programming. We then looked briefly at Spring's reactive programming efforts by introducing you to Project Reactor. After that, we explored Spring Security in a bit more detail to refresh your thoughts on this subject. Finally, we closed this chapter by giving you an idea of how examples would be structured in this book and what coding practices we will be using.

You should now have a good grasp on reactive programming, and on Spring Security and how it works. You should also have a clear understanding of how to go through the rest of the chapters, especially the example code.
