What is the proper way to implement OAuth2 Client and AuthServer in Spring Cloud (Microservice Architecture)

I was learning Microservice architecture from Spring Microservices In Action book.
As one of things I wanted to migrate examples which were built on Spring Boot 1.4.4 and Spring Cloud Camden.SR5 to Spring Boot 2.1.6 and Spring Cloud Greenwich.SR1.
Now, I'm having problems with migrating of OAuth2 Auth server and resource servers since Spring decided to change packages/placement of classes and I feel completly lost since nothing seems to work.
Documentation seems to be splitted into SpringBoot/SpringSecurity/SpringOAuth2 depedencies.

Enabling Actuator endpoints for Springboot app and embedded Netty server

i setup a service which uses spring boot application(for regular rest calls) and a embedded Netty server using NettyReactiveWebServerFactory in a different port (for eureka related calls).
All the actuator related functionality is applied to my main spring boot application but not to my embedded netty server.
Is there anyway where i can enable the actuator endpoints to both servers?
Used versions:
Spring boot version- 2.0.8, spring webflux
Spring cloud - Finchley.SR2
