Method Detail

getMatchingMapping

protected RequestMappingInfo getMatchingMapping(RequestMappingInfo info,
                                                ServerWebExchange exchange)

Check if the given RequestMappingInfo matches the current request and return a (potentially new) instance with conditions that match the current request -- for example with a subset of URL patterns.

Specified by:

getMatchingMapping in class AbstractHandlerMethodMapping<RequestMappingInfo>

Parameters:

info - the mapping to get a match for

exchange - the current exchange

Returns:

an info in case of a match; or null otherwise.

getMappingComparator

protected Comparator<RequestMappingInfo> getMappingComparator(ServerWebExchange exchange)

Provide a Comparator to sort RequestMappingInfos matched to a request.

Specified by:

getMappingComparator in class AbstractHandlerMethodMapping<RequestMappingInfo>

Parameters:

exchange - the current exchange

Returns:

the comparator (never null)

getHandlerInternal

public reactor.core.publisher.Mono<HandlerMethod> getHandlerInternal(ServerWebExchange exchange)

Description copied from class: AbstractHandlerMethodMapping

Look up a handler method for the given request.

Overrides:

getHandlerInternal in class AbstractHandlerMethodMapping<RequestMappingInfo>

Parameters:

exchange - the current exchange

Returns:

Mono for the matching handler, if any

handleMatch

protected void handleMatch(RequestMappingInfo info,
                           HandlerMethod handlerMethod,
                           ServerWebExchange exchange)

Expose URI template variables, matrix variables, and producible media types in the request.

Overrides:

handleMatch in class AbstractHandlerMethodMapping<RequestMappingInfo>

Parameters:

info - the matching mapping

handlerMethod - the matching method

exchange - the current exchange

See Also:

HandlerMapping.URI_TEMPLATE_VARIABLES_ATTRIBUTE, HandlerMapping.MATRIX_VARIABLES_ATTRIBUTE, HandlerMapping.PRODUCIBLE_MEDIA_TYPES_ATTRIBUTE

handleNoMatch

protected HandlerMethod handleNoMatch(Set<RequestMappingInfo> infos,
                                      ServerWebExchange exchange)
                               throws Exception

Iterate all RequestMappingInfos once again, look if any match by URL at least and raise exceptions accordingly.

Overrides:

handleNoMatch in class AbstractHandlerMethodMapping<RequestMappingInfo>

Parameters:

infos - all registered mappings

exchange - the current exchange

Returns:

an alternative HandlerMethod or null

Throws:

MethodNotAllowedException - for matches by URL but not by HTTP method

UnsupportedMediaTypeStatusException - if there are matches by URL and HTTP method but not by consumable media types

NotAcceptableStatusException - if there are matches by URL and HTTP method but not by producible media types

ServerWebInputException - if there are matches by URL and HTTP method but not by query parameter conditions

Exception - provides details that can be translated into an error status code
