This example project was created during the work on Spring Boot Buch. It started with Spring Security 4 and is now on 5.
While Spring Boot 1 had a managed version of the OAuth module, Spring Boot 2 doesnt and probably doesn't need it in the future as Spring Security 5 will have that stuff somewhen in its core.
In the meantime there's a project called OAuth2 Autoconfig for smoothing a migration.
It's used in this example.
