clone the project in https://spring.io/guides/gs/actuator-service/ that is https://github.com/spring-guides/gs-actuator-service.git , and start the application in complete folder
add in application.properties:
management.endpoints.web.exposure.include=*
logging.level.org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping: TRACE
logging.level.org.springframework.web: DEBUG
