Constructor Detail

AbstractWebFluxEndpointHandlerMapping

public AbstractWebFluxEndpointHandlerMapping(EndpointMapping endpointMapping,
                                             Collection<ExposableWebEndpoint> endpoints,
                                             EndpointMediaTypes endpointMediaTypes,
                                             CorsConfiguration corsConfiguration)

Creates a new AbstractWebFluxEndpointHandlerMapping that provides mappings for the operations of the given webEndpoints.

Parameters:

endpointMapping - the base mapping for all endpoints

endpoints - the web endpoints

endpointMediaTypes - media types consumed and produced by the endpoints

corsConfiguration - the CORS configuration for the endpoints

Method Detail

initHandlerMethods

protected void initHandlerMethods()

Overrides:

initHandlerMethods in class AbstractHandlerMethodMapping<RequestMappingInfo>

createHandlerMethod

protected HandlerMethod createHandlerMethod(Object handler,
                                            Method method)

Overrides:

createHandlerMethod in class AbstractHandlerMethodMapping<RequestMappingInfo>

wrapReactiveWebOperation

protected AbstractWebFluxEndpointHandlerMapping.ReactiveWebOperation wrapReactiveWebOperation(ExposableWebEndpoint endpoint,
                                                                                              WebOperation operation,
                                                                                              AbstractWebFluxEndpointHandlerMapping.ReactiveWebOperation reactiveWebOperation)

Hook point that allows subclasses to wrap the AbstractWebFluxEndpointHandlerMapping.ReactiveWebOperation before it's called. Allows additional features, such as security, to be added.

Parameters:

endpoint - the source endpoint

operation - the source operation

reactiveWebOperation - the reactive web operation to wrap

Returns:

a wrapped reactive web operation
