集成SpringActuator 健康监控

首先项目中引入SpringBoot起步Starter

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

启动项目

/info 代码里自定义信息

/health 健康检查 组件的状态检查

// 20180316134559
// http://localhost:8033/health

{
  "description": "Composite Discovery Client",
  "status": "UP",
  "discoveryComposite": {
    "description": "Composite Discovery Client",
    "status": "UP",
    "discoveryClient": {
      "description": "Composite Discovery Client",
      "status": "UP",
      "services": [
        "web"
      ]
    },
    "eureka": {
      "description": "Remote status from Eureka server",
      "status": "UP",
      "applications": {
        "WEB": 1
      }
    }
  },
  "diskSpace": {
    "status": "UP",
    "total": 500068036608,
    "free": 335228104704,
    "threshold": 10485760
  },
  "hystrix": {
    "status": "UP"
  }
}

/beans 目前Spring容器中所有的Bean

代码片段

[
  {
    "context": "web:dev:8033",
    "parent": "bootstrap",
    "beans": [
      {
        "bean": "webApplication",
        "aliases": [
          
        ],

        "resource": "null",
        "dependencies": [
          
        ]
      }
]

/autoconfig Spring中所有的自动配置

/dump 运行状态

/configprops 自动配置属性

这里放出我的自定义starter的自动配置属性

"spring.retrofit-com.onion.retrofit.retrofit.RetrofitProperties": {
    "prefix": "spring.retrofit",
    "properties": {
      "baseUrl": 
      "converterFactory": null
    }
  }

/env 环境属性

/mappings URL映射情况

{
  "/webjars/**": {
    "bean": "resourceHandlerMapping"
  },
  "/**": {
    "bean": "resourceHandlerMapping"
  },
  "/**/favicon.ico": {
    "bean": "faviconHandlerMapping"
  },
  "{[/web/get],methods=[GET]}": {
    "bean": "requestMappingHandlerMapping",
    "method": "public java.lang.String com.onion.web.controller.UserController.get() throws java.io.IOException"
  },
  "{[/web/register],methods=[POST]}": {
    "bean": "requestMappingHandlerMapping",
    "method": "public com.onion.pojo.HttpWrapper<com.onion.pojo.user.User> com.onion.web.controller.UserController.register(com.onion.pojo.user.User,java.lang.String,java.lang.String)"

    "method": "public com.onion.pojo.HttpWrapper<com.onion.pojo.user.PhoneAuthCode> com.onion.web.controller.UserController.getCode(java.lang.String)"
  }
}

/metrics 系统情况

/trace 最近的请求快照
