Replace Hystrix, Hystrix Dashboard, Ribon and Zuul

[arey]

According to the blog post titled Spring Cloud Greenwich.RC1 available now
https://spring.io/blog/2018/12/12/spring-cloud-greenwich-rc1-available-now, some Spring Cloud Netflix modules will be placed into maintenance mode.

Pivotal recommend the following as replacements for the functionality provided by these module:

CURRENT	REPLACEMENT
Hystrix	Resilience4j
Hystrix Dashboard / Turbine	Micrometer + Monitoring System
Ribbon	Spring Cloud Loadbalancer
Zuul 1	Spring Cloud Gateway
Archaius 1	Spring Boot external config + Spring Cloud Config

Pivotal intends to continue to support these modules for a period of at least a year from the general availability of the Greenwich release train.

Spring Cloud Circuit Breaker is a new project we could use to migrate from Hystrix to Resilience4J or Sentinel : https://www.infoq.com/news/2019/05/spring-cloud-pluggable-circuit

Thank you for good example @arey .
Is it possible to replace only Hystrix by Resilience4j
but not replace the others? :
2.Hystrix Dashboard / Turbine by Micrometer + Monitoring System
3. Ribbon by Spring Cloud Loadbalancer
4. Zuul by Spring Cloud Gateway
5.Archaius by Spring Boot external config + Spring Cloud Config

You could fork the repo, checkout an older version and apply the commit b501fdb

Sorry, @arey .
I use this project as beautiful example only. I am not going to change your project.
I work on replace Hystrix by Resilience4j in another our internal corporate microservice project.
Your answer can help me to select and estimate optimal way and time for replace Hystrix by Resilience4j for the internal corporate project.

Thank you @arey .
I see you added commits "Migrate from Netflix Zuul to Spring Cloud Gateway" before this commit.
Was it necessary to "Migrate from Netflix Zuul" before "Replace Hystrix by Spring Cloud Circuit Breaker and Resilience4j"?

Zuul and Hystrix are part of the Netflix OSS. Zuul creates a Hystrix circuit breaker for each route. I don't know if Zuul supports Resilience4j. But I don't think so.
