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 have covered two more authentication mechanisms, namely CAS and JAAS, supported by Spring Security, through hands-on coding examples. Again, we have used the sample application build as part of Chapter 2Deep Diving into Spring Security, as a base to explain the working and implementation of other authentication mechanisms. We then covered some important concepts and the customization possible in Spring Security.

In this chapter, we intentionally didn't use reactive programming in our coding examples. This chapter was aimed at making you understand the core concepts of each CAS and JAAS authentication mechanism by making use of the familiar Spring Web MVC application framework. We will cover reactive programming in more detail in Chapter 5Integrating with Spring WebFlux. We will start the next chapter by introducing you to Spring WebFlux and, in due course, implement Spring Security. While going through the main contents of Chapter 5Integrating with Spring...
