Review comment: When Spring context is loaded, `org.apache.servicecomb.core.CseApplicationListener` will load the handlers' configurations and providers' schema info, then register the microservice in the Service Center. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
