all services that are obtained in the implementation of Eureka through the Discoveryclient interface defined by spring cloud. Since spring cloud has done a very good job of abstraction in the service discovery layer, for the above program, we can seamlessly switch from Eureka's service governance system to Consul's service governance system Central.From now on, I will record the process and the essence of the recently developed Springcloud micro-service cloud architecture, and help more friends

restore the original master logic? For this problem, Hystrix also realized the automatic recovery function for us. When the circuit breaker opens, the main logic of the fuse, Hystrix will start a sleep time window, in this time window, the demotion logic is temporary into the primary logic, when the sleep time window expires, the circuit breaker will enter the semi-open state, release a request to the original master logic, if the request returned normally, Then the circuit breaker will continu
