A demo application show casing usage of OpenID Connect with Spring security without need of external libraries

Default redirect uri by spring security is

http://localhost:8080/login/oauth2/code/<<spring.security.oauth2.client.registration.provider>>

If you have set spring.security.oauth2.client.registration.provider this value to google then your redirect url should be http://localhost:8080/login/oauth2/code/google

See: OAuth2LoginAuthenticationFilter

Handling unauthenticated request:

When you request an endpoint unauthenticated, then spring security redirects to http://localhost:8080/oauth2/authorization/<<spring.security.oauth2.client.registration.provider>>

If you have set spring.security.oauth2.client.registration.provider this value to google, then the Identity provider config is fetched using a redirect to http://localhost:8080/oauth2/authorization/google, which then form the /authorize request according to the configuration and redirects
