Fields

Modifier and Type	Field and Description
static java.lang.String	BEST_MATCHING_HANDLER_ATTRIBUTE Name of the attribute that contains the mapped handler for the best matching pattern.
static java.lang.String	BEST_MATCHING_PATTERN_ATTRIBUTE Name of the attribute that contains the best matching pattern within the handler mapping.

Field Detail

BEST_MATCHING_HANDLER_ATTRIBUTE

static final java.lang.String BEST_MATCHING_HANDLER_ATTRIBUTE

Name of the attribute that contains the mapped handler for the best matching pattern.

BEST_MATCHING_PATTERN_ATTRIBUTE

static final java.lang.String BEST_MATCHING_PATTERN_ATTRIBUTE

Name of the attribute that contains the best matching pattern within the handler mapping.

PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE

static final java.lang.String PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE

Name of the attribute that contains the path within the handler mapping, in case of a pattern match such as "/static/**" or the full relevant URI otherwise.

Note: This attribute is not required to be supported by all HandlerMapping implementations. URL-based HandlerMappings will typically support it but handlers should not necessarily expect this request attribute to be present in all scenarios.

URI_TEMPLATE_VARIABLES_ATTRIBUTE

static final java.lang.String URI_TEMPLATE_VARIABLES_ATTRIBUTE

Name of the attribute that contains the URI templates map mapping variable names to values.

Note: This attribute is not required to be supported by all HandlerMapping implementations. URL-based HandlerMappings will typically support it, but handlers should not necessarily expect this request attribute to be present in all scenarios.

MATRIX_VARIABLES_ATTRIBUTE

static final java.lang.String MATRIX_VARIABLES_ATTRIBUTE

Name of the attribute that contains a map with URI variable names and a corresponding MultiValueMap of URI matrix variables for each.

Note: This attribute is not required to be supported by all HandlerMapping implementations and may also not be present depending on whether the HandlerMapping is configured to keep matrix variable content in the request URI.

PRODUCIBLE_MEDIA_TYPES_ATTRIBUTE

static final java.lang.String PRODUCIBLE_MEDIA_TYPES_ATTRIBUTE

Name of the attribute containing the set of producible MediaType's applicable to the mapped handler.

Note: This attribute is not required to be supported by all HandlerMapping implementations. Handlers should not necessarily expect this request attribute to be present in all scenarios.

Method Detail

getHandler

reactor.core.publisher.Mono<java.lang.Object> getHandler(ServerWebExchange exchange)

Return a handler for this request.

Parameters:

exchange - current server exchange

Returns:

a Mono that emits one value or none in case the request cannot be resolved to a handler
