Service discovery, discovering a list of dependent services
Service selection rules, how to select a valid service in multiple services
Service monitoring, detection of failed services, efficient elimination of failure services

We introduced the Eureka Service registration component through Springcloud, and implemented the HA with multiple machines, and also registered the Springboot service to Eureka. Today we will mainly introduce how to use these service interfaces as service consumers and implement the soft load balancing based on service. For the previously implemented Springboot rest interface services, generally restful interface to receive and split packets, you can through the Apache httpclient, JDK URLConnect
The Spring Cloud Ribbon is primarily used for client load balancing. The most basic usage is to use resttemplate for dynamic load balancing. We only need to add the following configuration to complete the client load balancing.
@Configuration Public class restconfiguration { @Bean @LoadBalanced public resttemplate Resttemplate () { returnnew resttemplate (); }}
