它是用于监控和管理Spring Boot应用程序的开源工具。它为开发人员或者是运维人员提供了友好的Web界面。可以实时监控和管理部署在不同环境中的Spring Boot应用。
二、提供了那些功能 应用程序监控可以显示程序的基本信息内存使用情况、线程信息。应用程序管理可以管理监控的应用动态配置日志的级别。通知和报警可以配置通知和警报当应用程序出现问题或者叨叨预定的阈值时及时通知相关人员。微服务支持可以适用微服务架构一次性监控和管理多个微服务应用。安全性可以与Spring Security集成实现对监控和管理界面的访问控制。 三、 使用Spring Boot Admin
示例项目整体结构 这里为什么要使用Eureka主要是想体现复用的思想。所有服务都注册到了Eureka之后而Spring Boot Admin只要集成了Eureka之后就能够获取到所有的服务信息注册信息。能够对所有注册到Eureka中的服务进行监控和管理。 Eureka的搭建可以参考这篇博客【Spring Cloud 三】Eureka服务注册与服务发现

EnableAdminServer //#开启admin服务端
public class AdminServerApplication {public static void main(String[] args) {SpringApplication.run(AdminServerApplication.class, args);}}
启动admin服务效果 3.2 common-api
这个模块是抽离出来的提供接口用于两个服务之间的跨服务调用。之后由服务消费者集成。

四、 总结
本篇博客主要是对于Spring Boot Admin的基本认识和基本运用通过本篇博客能够对Spring Boot Admin有一个宏观认知和能够快速上手。Spring Boot Admin还可以设置通知可报警本篇博客并没有涉及到。
