添加POM依赖:
<dependency> <groupId>org.springframework.bootgroupId> <artifactId>spring-boot-starter-actuatorartifactId> dependency> <dependency> <groupId>org.springframework.bootgroupId> <artifactId>spring-boot-starter-webartifactId> dependency>
application.yml中指定监控的HTTP端口(如果不指定,则使用和Server相同的端口);指定去掉某项的检查(比如不监控health.mail):
server port8083 management port8083 security enabled false #
监控和管理端点
端点名 | 描述 |
---|---|
autoconfig | 所有自动配置信息( positiveMatches :运行的, negativeMatches 未运行组件) |
auditevents | 审计事件 |
beans | 所有Bean的信息 |
configprops | 所有配置属性 |
dump | 线程状态信息 |
env | 当前环境信息 |
health | 应用健康状况 |
info | 当前应用信息 |
metrics | 应用的各项指标 |
mappings | 应用@RequestMapping映射路径 |
shutdown | 关闭当前应用(默认关闭) |
trace | 追踪信息(最新的http请求) |
heapdump | 下载内存快照 |
http://localhost:8083/info 读取配置文件application.properties的 info.*属性
在InfoProperties 读取
application.properties :
info.app.version=v1.2.0 info.app.name=abc
在GitProperties 获取git.properties 的信息
info.app.version=v1.2.0 info.app.name=abc #远程关闭开启 endpoints.shutdown.enabled=true #访问:http://localhost:8083/shutdown 关闭服务

org.springframework.boot.actuate.health 包下对于所有的健康状态检查例如:RedisHealthIndicator ,当有redis的starter 时候就会检查
{ status: "DOWN", //状态 diskSpace: { status: "UP", total: 395243941888, free: 367246643200, threshold: 10485760 }, rabbit: { status: "DOWN", error: "org.springframework.amqp.AmqpConnectException: java.net.ConnectException: Connection refused: connect" }, redis: { status: "UP", version: "4.0.9" }, db: { status: "UP", database: "MySQL", hello: 1 } }
自定义health
自定义健康状态指示器
1、编写一个指示器 实现 HealthIndicator 接口
2、指示器的名字 xxxxHealthIndicator
3、加入容器中
import org.springframework.boot.actuate.health.Health; import org.springframework.boot.actuate.health.HealthIndicator; import org.springframework.stereotype.Component; public class MyAppHealthIndicator implements HealthIndicator { public Health health() { //自定义的检查方法 //Health.up().build()代表健康 return Health.down().withDetail("msg","服务异常").build(); } }
