Securing OAuth2 Authentication Flow
摘要
Spring Security is a highly extensible and customizable framework. Its flexibility stems from being designed with object-oriented principles and best practices, ensuring it is open for extension while remaining closed for direct modification. In the previous chapter, we explored a key extension feature of Spring Security—the ability to integrate various authentication providers. This chapter focuses on one of the most widely used authorization frameworks, Open Authorization 2.0 (OAuth 2.0). It will guide you through creating a secure login application using Spring Boot, Spring Web, and the OAuth2 client to connect with Google as provider.
