SpringBoot四大神器之Actuator

来源：互联网发布：数据挖掘是算法吗编辑：程序博客网时间：2024/04/30 09:51

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。

使用actuator

添加依赖

       <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-actuator</artifactId>        </dependency>

主要暴露的功能

/health

{  status: "UP",  diskSpace: {    status: "UP",    total: 249779191808,    free: 193741590528,    threshold: 10485760  },  db: {    status: "UP",    database: "MySQL",    hello: 1  }}

/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"  }}

/shutdown

要真正生效，得配置文件开启

endpoints.shutdown.enabled: true

/trace

记录最近100个请求的信息
