从类复制的说明: AbstractRestHandler

This method is called for every incoming request and returns a CompletableFuture containing a the response.

Implementations may decide whether to throw RestHandlerExceptions or fail the returned CompletableFuture with a RestHandlerException.

Failing the future with another exception type or throwing unchecked exceptions is regarded as an implementation error as it does not allow us to provide a meaningful HTTP status code. In this case a HttpResponseStatus.INTERNAL_SERVER_ERROR will be returned.

指定者:

handleRequest 在类中 AbstractRestHandler<RestfulGateway,EmptyRequestBody,AsynchronousOperationResult<SavepointInfo>,SavepointStatusMessageParameters>

参数:

request - request that should be handled

gateway - leader gateway

返回:

future containing a handler response

抛出:

RestHandlerException - if the handling failed

getOperationKey

protected AsynchronousJobOperationKey getOperationKey(HandlerRequest<EmptyRequestBody> request)

exceptionalOperationResultResponse

protected SavepointInfo exceptionalOperationResultResponse(Throwable throwable)

operationResultResponse

protected SavepointInfo operationResultResponse(String operationResult)
