protected RequestMappingInfoHandlerMapping()

Method Detail

getMappingPathPatterns

protected Set<String> getMappingPathPatterns(RequestMappingInfo info)

Get the URL path patterns associated with this RequestMappingInfo.

Specified by:

getMappingPathPatterns in class AbstractHandlerMethodMapping<RequestMappingInfo>

getMatchingMapping

protected RequestMappingInfo getMatchingMapping(RequestMappingInfo info,
                                                HttpServletRequest request)

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

request - the current HTTP servlet request

Returns:

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

getMappingComparator

protected Comparator<RequestMappingInfo> getMappingComparator(HttpServletRequest request)

Provide a Comparator to sort RequestMappingInfos matched to a request.

Specified by:

getMappingComparator in class AbstractHandlerMethodMapping<RequestMappingInfo>

Parameters:

request - the current request

Returns:

the comparator, never null

handleMatch

protected void handleMatch(RequestMappingInfo info,
                           String lookupPath,
                           HttpServletRequest request)

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

Overrides:

handleMatch in class AbstractHandlerMethodMapping<RequestMappingInfo>

Parameters:

info - the matching mapping

lookupPath - mapping lookup path within the current servlet mapping

request - the current request

See Also:

HandlerMapping.URI_TEMPLATE_VARIABLES_ATTRIBUTE, HandlerMapping.MATRIX_VARIABLES_ATTRIBUTE, HandlerMapping.PRODUCIBLE_MEDIA_TYPES_ATTRIBUTE

handleNoMatch

protected HandlerMethod handleNoMatch(Set<RequestMappingInfo> requestMappingInfos,
                                      String lookupPath,
                                      HttpServletRequest request)
                               throws ServletException

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

Overrides:

handleNoMatch in class AbstractHandlerMethodMapping<RequestMappingInfo>

Parameters:

requestMappingInfos - all registered mappings

lookupPath - mapping lookup path within the current servlet mapping

request - the current request

Throws:

HttpRequestMethodNotSupportedException - if there are matches by URL but not by HTTP method

HttpMediaTypeNotAcceptableException - if there are matches by URL but not by consumable/producible media types

ServletException - in case of errors
