Eureka是基于 REST 的服务，来实现服务的发现与注册。不多说，直接提供代码。

1.maven依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

		</plugins>
	</build>
</project>

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服务的地址
      defaultZone: http://localhost:${server.port}/eureka/
  instance:
    leaseRenewalIntervalInSeconds: 10

#不使用Https
management:
  security:
    enabled: false

3.在启动类上加上注释

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

@SpringBootApplication
@EnableEurekaServer     //添加此注解，表示是eureka服务
public class Application {

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

eureka的搭建非常简单，主要还是看你是如何使用了.如果直接访问:http://localhost:2001/ ，就可以看到在eureka注册的服务有哪些。

可以看下大佬的博客，大佬写spring cloud的博客很详细：https://blog.csdn.net/forezp/article/details/70148833
