Spring Cloud Gateway

• Spring Boot Version: 2.5.7
• Spring Framework Version: 5.3.13

测试准备：

Replacements

We recommend the following as replacements for the functionality provided by these modules.

Current	Replacement
Hystrix	Resilience4j
Hystrix Dashboard / Turbine	Micrometer + Monitoring System
Ribbon	Spring Cloud Loadbalancer
Zuul 1	Spring Cloud Gateway
Achaius 1	Spring Boot external config + Spring Cloud Config

OpenFeign中的熔断器Hystrix在2020.0.0后不能继续使用

feign:
    hystrix:
        enable: true

取而代之的是：

feign:
    circuitbreaker:
        enable: true

服务降价需要替代方案，如： Resilience4j
