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.

Sample application

Let's gets our hands dirty by doing some coding. We will start off with the most common authentication mechanisms and then get into other authentication mechanisms that can be used with Spring Security.

Base project setup

Apart from the actual authentication mechanism, many aspects of the application are quite similar. In this section, we will set up the example and then cover the specific authentication mechanism in detail.


We will be using the default Spring Security DB schema against which we will authenticate the user. We will create a fully fledged Spring MVC web application, with each component being created from scratch. Creating a sample Spring Security application using Spring MVC with the help of Spring Boot is very easy. The application will function through many things that are hidden away from developers. But in this case, we will be creating this application component by component so that you can see the actual code with which a web application that is built...
