One of the new features introduced as a part of Spring Framework 5 is the introduction of a new reactive web application framework, Spring WebFlux. WebFlux lives alongside the well-established web application framework Spring MVC. The book aims to introduce reactive parts of Spring Security in which Spring WebFlux is one of the core components.
Making your application reactive brings in an asynchronous nature to your application. Traditional Java applications used threads to achieve parallel and asynchronous nature to the application, however, usage of threads for a web application is not scalable and efficient in any manner.
This chapter starts by introducing you to the core differences between Spring MVC and Spring WebFlux. It then delves into the Spring Security module and how reactive aspects have been brought into it.
In this chapter, we will cover the following topics:
- Spring MVC versus WebFlux
- Reactive support in Spring 5
- Spring WebFlux
- Spring WebFlux authentication architecture
- Spring WebFlux authorization
- Sample project
- Customization
