Open Authorization 2.0 (OAuth 2.0) and Spring Security

Spring Security is a very extendable and customizable framework. This is primarily because the framework is built using object-oriented principles and design practices so that it is open for extension and closed for modification. In the previous chapter, you saw one of the major extension points in Spring Security—namely, the pluggability of different authentication providers. This chapter covers the popular Open Authorization 2.0 (OAuth 2.0) framework. It shows how to develop login security applications using Spring Boot, Spring Web, and OAuth 2.0 client (security) toward GitHub and Google providers.
