## What it is
A demo application showing how to implement JWT-based authentication with Spring Security and Spring Boot 2, based on a minimal extraction of the JHipster codebase. It includes sample endpoints with role-based access control, an H2 database, and a small JavaScript client for testing.

## Use cases
- learn how to secure a Spring Boot REST API with JWT
- example of JWT authentication with Spring Security
- set up token-based login endpoints in Java
- understand role-based authorization in Spring Security
- starting point for adding JWT auth to a Spring Boot app
- see how to configure Spring Security filters for tokens

## When to choose
- you are learning JWT authentication in the Spring ecosystem
- you want a minimal, readable reference implementation to copy from
- you need a quick demo of role-based endpoint protection with Spring Security

## When to avoid
- you need a production-ready, actively maintained security solution
- you are not using Java or the Spring framework
- you require the latest Spring Boot 3 / Spring Security 6 features
