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.

In this chapter, we saw authentication mechanisms commonly used in the enterprises, namely SAML, LDAP, and OAuth/OIDC, supported by Spring Security through hands-on coding examples. We used the sample application built as part of Chapter 2, Deep Diving into Spring Security, as a basis for explaining the functionality and implementation of other authentication mechanisms.

However, we intentionally didn't reactive programming in our coding examples. This chapter was aimed at making you understand the core concepts of each of the authentication mechanisms, by making use of the familiar Spring Web MVC application framework. We will cover reactive programming in more detail inChapter 5Integrating with Spring WebFlux.
