SpringBoot服務(wù)監(jiān)控SpringBootAdmin的使用方法

本篇內(nèi)容主要講解“SpringBoot服務(wù)監(jiān)控SpringBootAdmin的使用方法”，感興趣的朋友不妨來(lái)看看。本文介紹的方法操作簡(jiǎn)單快捷，實(shí)用性強(qiáng)。下面就讓小編來(lái)帶大家學(xué)習(xí)“SpringBoot服務(wù)監(jiān)控SpringBootAdmin的使用方法”吧!

• github地址: https://github.com/codecentric/spring-boot-admin

• 文檔地址：https://codecentric.github.io/spring-boot-admin/current/

在項(xiàng)目中使用SpringBootAdmin分為兩部分: 服務(wù)端與客戶端?？蛻舳送ㄟ^(guò)http的方式向服務(wù)端提供自生的運(yùn)行狀況

• 版本: <spring.boot.admin.version>2.1.6</spring.boot.admin.version>

1. 構(gòu)建服務(wù)端項(xiàng)目

• 服務(wù)端依賴

             <dependency>
                <groupId>de.codecentric</groupId>
                <artifactId>spring-boot-admin-starter-server</artifactId>
                <version>${spring.boot.admin.version}</version>
            </dependency>

• 啟動(dòng)類上標(biāo)記注解@EnableAdminServer

• 設(shè)置端口

server:
  port: 8080

• 啟動(dòng)即可

如果有報(bào)錯(cuò):

2. 客戶端-需要被監(jiān)控的服務(wù)

• 添加客戶端依賴

       <dependency>
            <groupId>org.jolokia</groupId>
            <artifactId>jolokia-core</artifactId>
        </dependency>
        <!-- https://codecentric.github.io/spring-boot-admin/2.1.6/#getting-started-->
        <dependency>
            <groupId>de.codecentric</groupId>
            <artifactId>spring-boot-admin-starter-client</artifactId>
            <version>2.1.6</version>
        </dependency>

• 配置SpringBootAdmin服務(wù)端的地址

spring:
    boot:
        admin:
          client:
            url: http://localhost:8080

management:
  endpoints:
    web:
      exposure:
        include: "*"
  endpoint:
    health:
      show-details: always

• 啟動(dòng)SpringBoot客戶端項(xiàng)目

• 訪問(wèn)服務(wù)端配置的地址：http://localhost:8080

• 如果沒(méi)有數(shù)據(jù)，像下面這樣 這是因?yàn)槟愕腟pringBoot項(xiàng)目封裝了監(jiān)控端點(diǎn)返回的數(shù)據(jù)，從Info返回的數(shù)據(jù)結(jié)構(gòu)可以看出。

• 解決方案是，不要讓SpringBoot封裝監(jiān)控端點(diǎn)返回的數(shù)據(jù)

• 如果使用的是@RestControllerAdvice則約束一下包路徑@RestControllerAdvice("com.west.lake.blog.controller")

• 請(qǐng)求日志與請(qǐng)求耗時(shí)監(jiān)控

• 緩存管理器
