Secure a Spring Boot REST API with JWT authentication by configuring a SecurityConfig and a JwtAuthenticationFilter. This enforces stateless security, reducing boilerplate while ensuring consistent token validation across services.

Enforce role-based access control (RBAC) on Spring Security endpoints by applying method-level security with @PreAuthorize and @PostAuthorize annotations. This restricts REST endpoint permissions based on user roles.

Spring Security supports stateless JWT token rotation and expiration through a dedicated JwtService. It handles token generation, validates expiration, and manages secure access for REST APIs.

The best way to configure method-level security in a Spring Boot app is using @PreAuthorize and @PostAuthorize annotations within a stateless JWT setup. This ensures precise permission enforcement across REST endpoints.

You need jjwt libraries along with Spring Security to implement JWT authentication in Spring Boot. They provide the core token generation and parsing capabilities required by the JwtService.

Use a JwtAuthenticationFilter for stateless API security to intercept requests and validate tokens before they reach controllers. This ensures consistent JWT authentication and RBAC enforcement across all REST endpoints.
