Okay, so you're a micro-services developer and, several years ago, you decided to adopt Spring in general, and Spring Boot/Cloud in particular, as a development platform. You're a Java fullstack developer, meaning that you're working on the back-end side, as well as on the front-end side.
In your previous projects, you have implemented back-end micro-servicves with Spring Boot and you decided to use its out-of-the-box support of the Oauth 2.0 protocol, for authorization purposes and for its RBAC (Role Based Access) features. You've found this support very usefull and practical, hence, you'd like to continue using it in your future projects.
Should this be your case, please continue reading as you might have heard that that the mentioned support got deprecated.
