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.

We started off by giving adequate details on the framework itself at a high level. We went over a very basic example, and then, introduced you to Spring Security and its functionality with Spring WebFlux.

Finally, we went through a hands-on coding session, with a sample application. In this example, we covered other reactive aspects, such as Spring Data Mongo, so as to give you more insight into the reactive world.

We ended the chapter with some of the customization possible in Spring WebFlux with Spring Security.

Having read this chapter, you should have a clear idea of the differences between the Spring MVC and Spring WebFlux frameworks. You should also have a good understanding of the workings of Spring WebFlux security using the Spring Security module. The examples are meant to be simple in nature and as we are undressing Spring Security in this...
