本文详细介绍如何通过Maven依赖和YAML配置搭建Eureka Admin服务，实现对Eureka注册服务的详细信息查看，包括环境详情、内存和线程情况等。通过启用特定注解，服务可自动注册到Eureka，并通过提供的UI界面进行监控和管理。

虽然说在eureka的地址可以看到已经注册到此服务，但有时候需要看到此服务的详情，如：服务所在的环境详情、内存情况、线程情况等，都无法看到，此时需要用到eureka-admin。

1.maven依赖

2.application.yml配置

server:
  port: 2002

spring:
  application:
  #注册到eureka的名称
    name: admin-server
  boot:
    admin:
      routes:
        endpoints: env,metrics,trace,dump,jolokia,info,configprops,trace,logfile,refresh,flyway,liquibase,heapdump,hystrix.stream
#注册到eureka
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:2001/eureka/

management.security.enabled: false

3.启动类添加注解

import de.codecentric.boot.admin.config.EnableAdminServer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@SpringBootApplication
@EnableAdminServer       /**eureka-admin服务*/
@EnableDiscoveryClient   /**注册到eureka*/
public class XichuanEurekaAdminApplication {

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

直接运行，后可以看到eureka注册已经注册了eureka-admin
