Spring Security is the authentication and authorization framework specifically designed for Spring applications, addressing the critical need for secure application development. Created by the Spring team, it offers a robust solution to manage security requirements such as username/password authentication, OAuth2 / OIDC, JWT, method-level authorization, CSRF, and CORS. It provides a configuration DSL that, while initially complex, becomes intuitive with practice. The most recent 6.x release has simplified configuration processes significantly, moving away from the older XML-and-builders model. This makes it easier for developers to implement security features, such as OAuth2 resource servers and method-level security annotations, within their applications.
