Spring boot监控Actuator-Admin实现过程详解

Actuator是监控管理,不过没有可视化,这里就引入了admin-ui来解决Spring Boot Admin 分为Client端和Server端Client端是客户端Server端是spring-boot-admin来监控client的.先来一个Client客户端代码;

  <plugins>
   <plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
   </plugin>
  </plugins>
 </build>

</project>

application.yml文件,注意这里的url一定跑配置到Server的路径,不然找不到,有点类型erkura的注册中心地址.

server:
 port: 8081
 servlet:
  context-path: /demo
spring:
 application:
  # Spring Boot Admin展示的客户端项目名，不设置，会使用自动生成的随机id
  name: spring-boot-demo-admin-client
 boot:
  admin:
   client:
    # Spring Boot Admin 服务端地址
    url: "http://localhost:8080/"
    instance:
     metadata:
      # 客户端端点信息的安全认证信息
      user.name: ${spring.security.user.name}
      user.password: ${spring.security.user.password}
 security:
  user:
   name: xkcoding
   password: 123456
management:
 endpoint:
  health:
   # 端点健康情况，默认值"never"，设置为"always"可以显示硬盘使用情况和线程情况
   show-details: always
 endpoints:
  web:
   exposure:
    # 设置端点暴露的哪些内容，默认["health","info"]，设置"*"代表暴露所有可访问的端点
    include: "*"

Java文件就随便暴露个接口就行

package com.xkcoding.admin.client.controller;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * <p>
 * 首页
 * </p>
 *
 * @package: com.xkcoding.admin.client.controller
 * @description: 首页
 * @author: yangkai.shen
 * @date: Created in 2018/10/8 2:15 PM

 * @modified: yangkai.shen
 */
@RestController
public class IndexController {
  @GetMapping(value = {"", "/"})
  public String index() {
   return "This is a Spring Boot Admin Client.";
  }
}

接下来是Server服务端,作为监控平台使用pom.xml

<?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">

   <plugin>

    <artifactId>spring-boot-maven-plugin</artifactId>
   </plugin>
  </plugins>
 </build>

</project>

application.yml

server:
 port: 8080　

运行服务端地址,发现已经检测到了注册过的客户端

可以看到客户端的信息

http追踪可以看到请求
