Spring Boot Admin对SpringBoot服务进行监控-编程知识

Spring Boot Admin对SpringBoot服务进行监控

前面文章使用 Spring Boot Actuator 监控应用介绍了 Spring Boot Actuator 的使用，Spring Boot Actuator 提供

了对单个 Spring Boot 的监控，信息包含：应用状态、内存、线程、堆栈等等，比较全面的监控了 Spring Boot 应

用的整个生命周期。

但是这样监控也有一些问题：第一，所有的监控都需要调用固定的接口来查看，如果全面查看应用状态需要调用很

多接口，并且接口返回的 Json 信息不方便运营人员理解；第二，如果 Spring Boot 应用集群非常大，每个应用都

需要调用不同的接口来查看监控信息，操作非常繁琐低效。在这样的背景下，就诞生了另外一个开源软件：

Spring Boot Admin。

1、什么是Spring Boot Admin?

Spring Boot Admin 是一个管理和监控 Spring Boot 应用程序的开源软件。每个应用都认为是一个客户端，通过

HTTP 或者使用 Eureka 注册到 admin server 中进行展示，Spring Boot Admin UI 部分使用 VueJs 将数据展示在

前端。这篇文章给大家介绍如何使用 Spring Boot Admin 对 Spring Boot 应用进行监控。

2、监控单体应用

这节给大家展示如何使用 Spring Boot Admin 监控单个 Spring Boot 应用。

2.2.2 配置文件

server.port=8000

服务端设置端口为：8000。

2.2.3 启动类

package com.example;import de.codecentric.boot.admin.server.config.EnableAdminServer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Configuration;@Configuration
@EnableAutoConfiguration
@EnableAdminServer
@SpringBootApplication
public class SpringBootAdminServerApplication {public static void main(String[] args) {SpringApplication.run(SpringBootAdminServerApplication.class, args);}}

完成上面三步之后，启动服务端，浏览器访问http://localhost:8000可以看到以下界面：

2.3 Admin Client 端

2.3.1 项目依赖

<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 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>com.example</groupId><artifactId>spring-boot-admin-simple</artifactId><version>0.0.1-SNAPSHOT</version></parent><groupId>com.example</groupId><artifactId>spring-boot-admin-client</artifactId><version>0.0.1-SNAPSHOT</version><name>spring-boot-admin-client</name><description>spring-boot-admin-client</description><packaging>jar</packaging><properties><java.version>1.8</java.version></properties><dependencies><dependency><groupId>de.codecentric</groupId><artifactId>spring-boot-admin-starter-client</artifactId><version>2.1.0</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId><exclusions><exclusion><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-tomcat</artifactId></exclusion></exclusions></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-jetty</artifactId></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>

2.3.2 配置文件

server.port=8001spring.application.name=Admin Client
spring.boot.admin.client.url=http://localhost:8000
management.endpoints.web.exposure.include=*

spring.boot.admin.client.url 配置 Admin Server 的地址
management.endpoints.web.exposure.include=* 打开客户端 Actuator 的监控。

2.3.3 启动类

package com.example;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication
public class SpringBootAdminClientApplication {public static void main(String[] args) {SpringApplication.run(SpringBootAdminClientApplication.class, args);}}

配置完成之后，启动 Client 端，Admin 服务端会自动检查到客户端的变化，并展示其应用

在这里插入图片描述

页面会展示被监控的服务列表，点击详项目名称会进入此应用的详细监控信息。

在这里插入图片描述

通过上图可以看出，Spring Boot Admin 以图形化的形式展示了应用的各项信息，这些信息大多都来自于 Spring

Boot Actuator 提供的接口。

3、监控微服务

如果我们使用的是单个 Spring Boot 应用，就需要在每一个被监控的应用中配置 Admin Server 的地址信息；如果

应用都注册在 Eureka 中就不需要再对每个应用进行配置，Spring Boot Admin 会自动从注册中心抓取应用的相关

信息。

如果我们使用了 Spring Cloud 的服务发现功能，就不需要在单独添加 Admin Client 客户端，仅仅需要 Spring

Boot Server，其它内容会自动进行配置。

接下来我们以 Eureka 作为服务发现的示例来进行演示，实际上也可以使用 Consul 或者 Zookeeper。
