## What it is
A Spring Boot 3.5 + Java 21 example project demonstrating stateless authentication and role-based authorization using Spring Security and JWT, with Redis-backed token session management and JPA for persistence. It is primarily an educational guide for developers learning Spring Security.

## Use cases
- learn how to implement JWT login and logout with Spring Security
- example of role-based access control with @PreAuthorize
- see how to store and invalidate tokens in Redis
- learn JPA many-to-many mapping with a join table and auditing
- starting point for a Spring Boot auth demo with H2 in-memory database

## When to choose
- you are learning Spring Security + JWT from a working, up-to-date example
- you need a reference for token invalidation on logout/re-login using Redis
- you want a minimal runnable Spring Boot auth demo without installing MySQL

## When to avoid
- you need a production-ready, hardened authentication service
- you require a maintained library with a license and long-term support
- you use a stack outside Spring Boot/Java

## Facets
- artifact type: learning-resource
- maturity: active
- function: auth, authorization, orm, caching, api-framework
- domain: security, backend, developer-tools, tutorials, web-development
- platform: jvm, self-hosted
