并且结合了Ribbon和Eureka,做到了客户端的负载均衡,假如有两个端口不同的服务启动,接口同时注册在Spring Eureka上,并起同样的名字服务,客户端调用服务时两次,该服务下两个端口下的接口会分别被调用一次,客户端自动去做了负载均衡这件事。 该案例实现,可以建立三个工程,三个工程分别是eureka-feign(客户端)、Register-...

Eureka Client在默认的情况下会每隔30秒(eureka.instance.leaseRenewalIntervalInSeconds)发送一次心跳来进行服务续约。 【3】服务同步(replicate):Eureka Server之间会互相进行注册,构建Eureka Server集群,不同Eureka Server之间会进行服务同步,用来保证服务信息的一致性。
