Method Detail

getHandlerInternal

protected java.lang.Object getHandlerInternal(HttpServletRequest request)

Description copied from class: AbstractHandlerMapping

Look up a handler for the given request, returning null if no specific one is found. This method is called by AbstractHandlerMapping.getHandler(HttpServletRequest); a null return value will lead to the default handler, if one is set.

On CORS pre-flight requests this method should return a match not for the pre-flight request but for the expected actual request based on the URL path, the HTTP methods from the "Access-Control-Request-Method" header, and the headers from the "Access-Control-Request-Headers" header thus allowing the CORS configuration to be obtained via AbstractHandlerMapping.getCorsConfigurations(),

Note: This method may also return a pre-built HandlerExecutionChain, combining a handler object with dynamically determined interceptors. Statically specified interceptors will get merged into such an existing chain.

Specified by:

getHandlerInternal in class AbstractHandlerMapping

Parameters:

request - current HTTP request

Returns:

the corresponding handler instance, or null if none found
