switch service governance implementations without affecting any other logic such as service registration, service discovery, service invocation, and so on.So, let's introduce the benefits of the abstraction from spring cloud by introducing two implementations of service governance.Spring Cloud EurekaFirst, let's try using spring Cloud Eureka to implement service governance.Spring Cloud Eureka is the Service governance module under the spring Cloud Netflix project. The spring cloud Netflix proje

implementation of the eureka-client Eureka through the interfaces defined by spring cloud DiscoveryClient . 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 who are intereste

restTemplate.getForObject(url, String.class);}}As you can see here, we inject loadbalancerclient and resttemplate, and in the implementation of the/consumer interface, First, a Eureka-client service instance is selected through the Choose function of Loadbalancerclient, which is stored in serviceinstance, and the information in these objects is then spliced out to access/ The detailed address of the DC interface, and finally uses the Resttemplate object to implement the call to the service prov

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 Application {public static void main(String[] args) {new SpringApplicationBuilder(Applicati
