Create a basic spring boot project, named Eureka-server, and introduce the required dependencies in the Pom.xml:Start a service registry with @enableeurekaserver annotations to provide conversations to other apps. This step is very simple, just add this annotation to a normal spring boot application to enable this feature, such as the following example:@EnableEurekaServer@SpringBootApplicationpublic class A

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

We can see from the console of the eureka-client that the service provider outputs the results that were originally to be returned, but because the service consumer triggered a service request timeout exception due to a delay of 5 seconds before it was returned, the service consumer was executed by the downgrade logic specified in the Hystrixcommand annotation , so the result of the request returned fallback.
