spring boot 通过actuator 来提供应用服务器信息。例如可以通过health 查看存储信息,服务器是否正常运行 通过metrics可以观察heap, mem等信息。 方便用户监控应用


1 在pom.xml 添加actuator 依赖

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


2 在application.properties 配置详细信息

management.context-path=/manageendpoints.health.sensitive=falseendpoints.metrics.sensitive=falseendpoints.info.sensitive=falsemanagement.context-path=/manageendpoints.health.sensitive=falseendpoints.metrics.sensitive=falseendpoints.info.sensitive=false#configinfodetailsinfo.app.name=MyAppinfo.app.description=descriptfortheprojectinfo.build.groupId=@project.groupId@info.build.artiface=@project.artifactId@info.build.version=@project.version@info.app.encoding=@project.build.sourceEncoding@info.app.java.source=@java.version@info.app.java.target=@java.version@


3 测试这里我配置了/manage 为actuator的根路径

输入localhost:8080/manage/health

{"status":"UP","diskSpace":{"status":"UP","total":255534821376,"free":107373064192,"threshold":10485760},"db":{"status":"UP","database":"Oracle","hello":"Hello"}}

输入localhost:8080/manage/metrics

{"mem":374672,"mem.free":112188,"processors":4,"instance.uptime":182778,"uptime":199229,"systemload.average":-1.0,"heap.committed":310272,"heap.init":253952,"heap.used":198083,"heap":3592192,"nonheap.committed":66176,"nonheap.init":2496,"nonheap.used":64401,"nonheap":0,"threads.peak":33,"threads.daemon":31,"threads.totalStarted":40,"threads":33,"classes":7965,"classes.loaded":7967,"classes.unloaded":2,"gc.ps_scavenge.count":12,"gc.ps_scavenge.time":233,"gc.ps_marksweep.count":2,"gc.ps_marksweep.time":139,"httpsessions.max":-1,"httpsessions.active":0,"gauge.response.star-star":12.0,"gauge.response.manage.health":935.0,"counter.status.404.star-star":2,"counter.status.200.manage.health":1}
