triggerOperation 在类中 AbstractAsynchronousOperationHandlers.TriggerHandler<RestfulGateway,SavepointTriggerRequestBody,SavepointTriggerMessageParameters>

参数:

request - with which the trigger handler has been called

gateway - to the leader

返回:

Future result of the asynchronous operation

抛出:

RestHandlerException - if something went wrong
