## What it is
A companion repository of example modules for Baeldung's Spring Security OAuth tutorials and the 'Learn Spring Security OAuth' course. It contains runnable Spring Boot authorization servers, resource servers, and Angular/React client apps demonstrating OAuth2 flows including JWT, JWS/JWK, and PKCE for JavaScript-only SPAs.

## Use cases
- learn how to implement OAuth2 with Spring Security
- set up an authorization server with Keycloak and a Spring resource server
- secure a REST API with JWT tokens in Spring Boot
- implement the authorization code flow with PKCE in a JavaScript SPA
- see working examples of legacy Spring Security OAuth2 configurations
- understand JWS and JWK usage in Spring Security OAuth2

## When to choose
- you are learning Spring Security's OAuth2 stack from Baeldung tutorials or the LSSO course
- you need runnable reference implementations of OAuth2 clients, resource servers, and authorization servers in Java
- you want to compare legacy Spring Security OAuth with the newer Spring Security 5 OAuth2 stack

## When to avoid
- you need a production-ready OAuth library or framework to drop into your project
- you want actively maintained, up-to-date example code for the latest Spring Security releases
- you are not using the Java/Spring ecosystem

## Facets
- artifact type: learning-resource
