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spring-boot-starter-actuator



org.springframework.boot
spring-boot-starter-actuator

/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

"phone": "0755-82890987",

要真正生效,得配置文件开启


endpoints.shutdown.enabled: true
