Spring Boot Admin - 爱码网

一、简介

官方文档 http://codecentric.github.io/spring-boot-admin/2.0.2/

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或者服务注册发现Spring Cloud(Eureka、Consul等等)注册到admin server中进行展示，Spring Boot Admin UI部分使用AngularJs将数据展示在前端。

Spring Boot Admin是一个针对spring-boot的actuator接口进行UI美化封装的监控工具。它可以：在列表中浏览所有被监控spring-boot项目的基本信息，详细的Health信息、内存信息、JVM信息、垃圾回收信息、各种配置信息（比如数据源、缓存列表和命中率）等，还可以直接修改logger的level。

二、环境

一个eureka项目

一个Spring Boot Admin项目

三、创建eureka项目

（1）创建项目

创建一个spring boot项目

Spring Boot Admin

（2）依赖

（3）application.yml配置




server:



  port: 8000




 



eureka:



  instance:



    hostname: localhost  # 指定Eureka主机




  client:



    register-with-eureka: false   # 指定当前主机是否向Eureka服务器进行注册




    fetch-registry: false    # 指定当前主机是否要从Eurka服务器下载服务注册列表




    service-url:   # 服务暴露地址

#     defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka



 



#  server:



#    enable-self-preservation: false    # 关闭自我保护

（4）启动类





package com.abc.eureka;



 




import org.springframework.boot.SpringApplication;




import org.springframework.boot.autoconfigure.SpringBootApplication;




import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;



 



@SpringBootApplication




@EnableEurekaServer   // 开启Eureka服务





public class EurekaServerApplication {



 



    public static void main(String[] args) {



        SpringApplication.run(EurekaServerApplication.class, args);



    }



}
