The configuration file

　　

application.yml

Server: port: 8761 #

Spring: Application: name: eureka-server #

Configure the Eureka Server registry

Client: register-with-eureka: instance: hostname: localhost False # Whether to fetch service registration information from the registry, default is true service-url: DefaultZone: http:// eureka.instance.hostname:{eureka.instance.hostname}:eureka.instance.hostname:{server.port}/eureka/

At this point if directly start the project will be an error, error message: com. Sun. Jersey. API. Client. ClientHandlerException: java.net.ConnectException: Connection refused: connect

This is because Eureka has enabled registering itself in the registry and obtaining service registration information from the registry by default, which is turned off if the application is a single node in the role of the registry.

　　

Start the class

　　

EurekaServerApplication.java

package com.example;

import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@enableEurekaserver Public class EurekaServerApplication {

public static void main(String[] args) {
    SpringApplication.run(EurekaServerApplication.class, args);
}
Copy the code

}

Today to say the Eureka entry case temporarily said so much, to learn more about technology dry goods, pay attention to the public number [letbyte send 123 can understand, we learn together acro], I am Miles, an interesting soul! See you next time!
