Spring Boot Admin 客户端

创建 Spring Boot Admin Client

创建一个工程名为 hello-spring-cloud-admin-client 的项目,pom.xml 文件如下:

<?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"

主要增加了 2 个依赖,org.jolokia:jolokia-corede.codecentric:spring-boot-admin-starter-client

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

其中 spring-boot-admin-starter-client 的版本号为:2.0.0,这里没写版本号是因为我已将版本号托管到 dependencies 项目中

Application

程序入口类没有特别需要修改的地方

package com.funtl.hello.spring.cloud.admin.client;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

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

application.yml

设置端口号为:8085,并设置 Spring Boot Admin 的服务端地址

spring:
  application:
    name: hello-spring-cloud-admin-client
  boot:
    admin:
      client:
        url: http://localhost:8084
  zipkin:
    base-url: http://localhost:9411

server:
  port: 8085

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/

    admin:
      client:
        url: http://localhost:8084

测试服务监控

依次启动两个应用,打开浏览器访问:http://localhost:8084 界面显示如下

从图中可以看到,我们的 Admin Client 已经上线了,至此说明监控中心搭建成功
