主要依赖

    <artifactId>jolokia-core</artifactId>
</dependency>
<dependency>
    <groupId>de.codecentric</groupId>
    <artifactId>spring-boot-admin-starter-server</artifactId>
</dependency>

spring-boot-admin-starter-server 的版本号为：2.0.1，这里没写版本号是因为我已将版本号托管到 dependencies 项目

<spring-boot-admin.version>2.0.1</spring-boot-admin.version>

在此项目的入口类AdminApplication.class中添加注解启动@EnableAdminServer 注解开启 Admin 功能

package com.lxq.hello.spring.cloud.admin;

import de.codecentric.boot.admin.server.config.EnableAdminServer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

/**

 */

@SpringBootApplication
@EnableAdminServer
@EnableEurekaClient
public class AdminApplication {
    public static void main(String[] args) {
        SpringApplication.run(AdminApplication.class,args);
    }
}
