Spring Boot Admin

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

（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://localhost:8000/eureka
#     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);
    }
}
