Authorization & Role-Based Access Control
Module 13 answered "who are you." This module is "what are you allowed to do" — and the two places in Spring Security you can actually enforce that answer.
Learning objectives
- Beginner: URL-based role rules only, sufficient when authorization genuinely tracks request paths cleanly (e.g. all of /admin/** is admin-only).
- Intermediate: @PreAuthorize at the service layer for operations needing more than a URL pattern can express, keeping the rule next to the code it protects.
- Advanced: Custom bean-referencing SpEL expressions combining role and resource-ownership checks, for genuinely fine-grained, per-resource authorization.
