RequestMappingInfoHandlerMapping

protected RequestMappingInfoHandlerMapping()

Method Details

getDirectPaths

protected Set<String> getDirectPaths(RequestMappingInfo info)

Description copied from class: AbstractHandlerMethodMapping

Return the request mapping paths that are not patterns.

Overrides:

getDirectPaths in class AbstractHandlerMethodMapping<RequestMappingInfo>

getMatchingMapping

protected @Nullable 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)

getHandlerInternal

protected @Nullable HandlerMethod getHandlerInternal(HttpServletRequest request)
                                              throws Exception

Description copied from class: AbstractHandlerMethodMapping

Look up a handler method for the given request.

Overrides:

getHandlerInternal in class AbstractHandlerMethodMapping<RequestMappingInfo>

Parameters:

request - current HTTP request

Returns:

the corresponding handler instance, or null if none found

Throws:

Exception - if there is an internal error

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 @Nullable HandlerMethod handleNoMatch(Set<RequestMappingInfo> infos,
 String lookupPath,
 HttpServletRequest request)
                                         throws ServletException

Iterate all RequestMappingInfo's once again, look if any match by URL at least and raise exceptions according to what doesn't match.

Overrides:

handleNoMatch in class AbstractHandlerMethodMapping<RequestMappingInfo>

Parameters:

infos - 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
