sample for OAuth authorization code grant type with spring boot 2.x

[robin]

i am looking for a sample for OAuth authorization code grant type with spring boot 2.x

I couldn't find any online. Can apigee folks share something.

the one i found on github from apigee samples is based on nodejs.

https://github.com/apigee/api-platform-samples/tree/master/sample-proxies/oauth-advanced

a similar sample that uses spring boot 2.x will be very helpful.
