Actuator如何在SpringBoot中使用

今天就跟大家聊聊有关Actuator如何在SpringBoot中使用，可能很多人都不太了解，为了让大家更加了解，小编给大家总结了以下内容，希望大家根据这篇文章可以有所收获。

Spring Boot有四大神器，分别是auto-configuration、starters、cli、actuator，本文主要讲actuator。actuator是spring boot提供的对应用系统的自省和监控的集成功能，可以对应用系统进行配置查看、相关功能统计等。

spring-boot-starter-actuator模块的实现对于实施微服务的中小团队来说，可以有效地减少监控系统在采集应用指标时的开发量。当然，它也并不是万能的，有时候我们也需要对其做一些简单的扩展来帮助我们实现自身系统个性化的监控需求。下面，在本文中，我们将详解的介绍一些关于spring-boot-starter-actuator模块的内容，包括它的原生提供的端点以及一些常用的扩展和配置方式。

使用actuator

添加依赖

/info

需要自己在application.properties里头添加信息，比如

info: contact:  email: xixicat@gmail.com  phone: 0755-82890987

然后请求就可以出来了

{ "contact": {   "phone": "0755-82890987",   "email": "xixicat@gmail.com" }}

要真正生效，得配置文件开启

endpoints.shutdown.enabled: true
