spring boot 通過actuator 來提供應用服務器信息。例如可以通過health 查看存儲信息,服務器是否正常運行 通過metrics可以觀察heap, mem等信息。 方便用戶監控應用
1 在pom.xml 添加actuator 依賴
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency>
2 在application.properties 配置詳細信息
management.context-path=/manage endpoints.health.sensitive=false endpoints.metrics.sensitive=false endpoints.info.sensitive=false management.context-path=/manage endpoints.health.sensitive=false endpoints.metrics.sensitive=false endpoints.info.sensitive=false #config info details info.app.name=MyApp info.app.description=descript for the project [email protected]@ [email protected]@ [email protected]@ [email protected]@ [email protected]@ [email protected]@
3 測試這裏我配置了/manage 爲actuator的根路徑
輸入localhost:8080/manage/health
{"status":"UP","diskSpace":{"status":"UP","total":255534821376,"free":107373064192,"threshold":10485760},"db":{"status":"UP","database":"Oracle","hello":"Hello"}}輸入localhost:8080/manage/metrics
