Method Detail
getMappingPathPatterns
protected Set<String> getMappingPathPatterns(RequestMappingInfo info)
Get the URL path patterns associated with the suppliedRequestMappingInfo
.- Specified by:
getMappingPathPatterns
in classAbstractHandlerMethodMapping<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 classAbstractHandlerMethodMapping<RequestMappingInfo>
- Parameters:
info
- the mapping to get a match forrequest
- the current HTTP servlet request- Returns:
- an info in case of a match; or
null
otherwise.
getMappingComparator
