In a microservices architecture, the service is split into services according to the business, and the service and service can call each other (RPC), which can be invoked with Resttemplate+ribbon and feign in spring cloud. To ensure their high availability, a single service is typically deployed in a cluster. Due to network reasons or their own reasons, the service does not guarantee that 100% is available, if a single service problem, call the service will be a thread blocking, if there is a la
