Eureka是基於 REST 的服務，來實現服務的發現與註冊。不多說，直接提供程式碼。

1.maven依賴

2.application.yml配置

spring:
  application:
    name: xichuan-eureka

server:
  port: 2001

eureka:
  client:
    register-with-eureka: false
    fetch-registry: false
    registryFetchIntervalSeconds: 5
    serviceUrl:
    #eureka服務的地址
      defaultZone: http://localhost:${server.port}/eureka/
  instance:
    leaseRenewalIntervalInSeconds: 10

#不使用Https
management:
  security:
    enabled: false
 

3.在啟動類上加上註釋

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

@SpringBootApplication
@EnableEurekaServer     //新增此註解，表示是eureka服務
public class Application {

	public static void main(String[] args) {
		SpringApplication.run(Application.class, args);
	}
}
 

eureka的搭建非常簡單，主要還是看你是如何使用了.如果直接訪問:http://localhost:2001/ ，就可以看到在eureka註冊的服務有哪些。

可以看下大佬的部落格，大佬寫spring cloud的部落格很詳細：https://blog.csdn.net/forezp/article/details/70148833
