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.

We started this chapter by introducing you to some of the important concepts that are needed to follow along with it. We then covered the important characteristics needed in a modern web application. We quickly covered an architecture called SOFEA, which aptly covers how we would like to build modern applications. We then got our hands dirty by implementing security for REST APIs in the simplest of ways.

In the following section, we covered how we can secure a REST API in a more advanced fashion employing OAuth, using a JWT. We started this section by introducing many concepts in regards to OAuth and finally concluded the chapter with a full-fledged sample project that uses OAuth and JWT.

After reading this chapter, you should have a clear understanding of REST, OAuth, and JWT. You should also be comfortable with using Spring Security in the next chapter, to secure the RESTful endpoints exposed in your application.
