创建服务端

新建SpringBoot工程springcloud-admin,pom.xml文件配置如下:

            </plugin>
        </plugins>
    </build>

</project>

主要增加了spring-boot-admin-starter-server的依赖

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

Application

通过@EnableAdminServer注解开启Admin服务监控功能。

package com.springcloud.bh;

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 ApringcloudAdminApplication {

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

appliction.yml

设置端口号为:8084

server:
  port: 8084

spring:
  application:
    name: springcloud-admin-server

eureka:
  client:
    service-url:
      defaultZone: http://localhost:8761/eureka/

创建客户端

在之前的项目springcloud-example的每个Module项目中添加pom依赖

<dependency>
    <groupId>de.codecentric</groupId>
    <artifactId>spring-boot-admin-client</artifactId>
    <version>2.1.0</version>
</dependency>
<dependency>
    <groupId>org.jolokia</groupId>
    <artifactId>jolokia-core</artifactId>
    <version>1.6.2</version>
</dependency>

在application.yml中添加以下配置

spring:
  boot:
    admin:
      client:
        url: http://localhost:8084  #springboot-admin服务监控server地址

测试访问

启动所有项目后访问http://localhost:8084 即可看到服务监控页面
