## What it is
A Java demo project and tutorial explaining how to implement OAuth2 with Spring Security OAuth2, including authorization code flow examples and Spring Boot 2.0 migration guidance. It serves as a hands-on learning resource for developers integrating OAuth2 authentication in Spring applications.

## Use cases
- learn how oauth2 authorization code flow works in spring security
- example of spring security oauth2 configuration
- migrate spring security oauth2 to spring boot 2.0
- understand oauth2 filter chains in spring
- demo of getting access token with authorization code
- set up password encoder in spring boot 2 security

## When to choose
- you are learning OAuth2 concepts with Spring Security from scratch
- you need a working demo of the authorization code flow
- you are migrating a Spring Security OAuth2 app to Spring Boot 2.0

## When to avoid
- you need a production-ready OAuth2 server or client
- you use modern Spring Boot 3 / Spring Authorization Server
- you need maintained, licensed software with active support

- function: auth, authorization, security
- domain: security, web-development, developer-tools, tutorials
