shouldApplyTo
protected boolean shouldApplyTo(HttpServletRequest request, Object handler)
Checks if the handler is aHandlerMethod
and then delegates to the base class implementation of#shouldApplyTo(HttpServletRequest, Object)
passing the bean of theHandlerMethod
. Otherwise returnsfalse
.- Overrides:
shouldApplyTo
in classAbstractHandlerExceptionResolver
- Parameters:
request
- current HTTP requesthandler
- the executed handler, ornull
if none chosen at the time of the exception (for example, if multipart resolution failed)- Returns:
- whether this resolved should proceed with resolving the exception for the given request and handler

doResolveException
protected final ModelAndView doResolveException(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)
Description copied from class:AbstractHandlerExceptionResolver
Actually resolve the given exception that got thrown during handler execution, returning aModelAndView
that represents a specific error page if appropriate.May be overridden in subclasses, in order to apply specific exception checks. Note that this template method will be invoked after checking whether this resolved applies ("mappedHandlers" etc), so an implementation may simply proceed with its actual exception handling.
- Specified by:
doResolveException
in classAbstractHandlerExceptionResolver
- Parameters:
request
- current HTTP requestresponse
- current HTTP responsehandler
- the executed handler, ornull
if none chosen at the time of the exception (for example, if multipart resolution failed)ex
- the exception that got thrown during handler execution- Returns:
- a corresponding
ModelAndView
to forward to, ornull
for default processing in the resolution chain
doResolveHandlerMethodException
protected abstract ModelAndView doResolveHandlerMethodException(HttpServletRequest request, HttpServletResponse response, HandlerMethod handlerMethod, Exception ex)
Actually resolve the given exception that got thrown during on handler execution, returning a ModelAndView that represents a specific error page if appropriate.May be overridden in subclasses, in order to apply specific exception checks. Note that this template method will be invoked after checking whether this resolved applies ("mappedHandlers" etc), so an implementation may simply proceed with its actual exception handling.
- Parameters:
request
- current HTTP requestresponse
- current HTTP responsehandlerMethod
- the executed handler method, ornull
if none chosen at the time of the exception (for example, if multipart resolution failed)ex
- the exception that got thrown during handler execution- Returns:
- a corresponding ModelAndView to forward to, or
null
for default processing
