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


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

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" } }

/mappings

{        {          [/metrics || /metrics.json], methods = [GET], produces = [application / json]        }: {          bean: "endpointHandlerMapping",          method: "public java.lang.Object org.springframework.boot.actuate.endpoint.mvc.EndpointMvcAdapter.invoke()"        }, {          [/beans || /beans.json], methods = [GET], produces = [application / json]        }: {          bean: "endpointHandlerMapping",          method: "public java.lang.Object org.springframework.boot.actuate.endpoint.mvc.EndpointMvcAdapter.invoke()"        }, {          [/health || /health.json], produces = [application / json]        }: {          bean: "endpointHandlerMapping", method: "public java.lang.Object org.springframework.boot.actuate.endpoint.mvc.HealthMvcEndpoint.invoke(java.security.Principal)" }, { [/info || /info.json], methods = [GET], produces = [application / json] }: { bean: "endpointHandlerMapping", method: "public java.lang.Object org.springframework.boot.actuate.endpoint.mvc.EndpointMvcAdapter.invoke()" }, { [/trace || /trace.json], methods = [GET], produces = [application / json] }: { bean: "endpointHandlerMapping", method: "public java.lang.Object org.springframework.boot.actuate.endpoint.mvc.EndpointMvcAdapter.invoke()" }, { [/autoconfig || /autoconfig.json], methods = [GET], produces = [application / json] }: { bean: "endpointHandlerMapping", method: "public java.lang.Object org.springframework.boot.actuate.endpoint.mvc.EndpointMvcAdapter.invoke()" } }

/metrics

/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
