Method Detail

doResolveException

protected ModelAndView doResolveException(javax.servlet.http.HttpServletRequest request,
                                          javax.servlet.http.HttpServletResponse response,

                                          java.lang.Exception ex)
Description copied from class: AbstractHandlerExceptionResolver
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.

Specified by:
doResolveException in class AbstractHandlerExceptionResolver
Parameters:
request - current HTTP request
response - current HTTP response
handler - the executed handler, or null 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

resolveResponseStatus

protected ModelAndView resolveResponseStatus(ResponseStatus responseStatus,
                                             javax.servlet.http.HttpServletRequest request,
                                             javax.servlet.http.HttpServletResponse response,
                                             java.lang.Object handler,
                                             java.lang.Exception ex)
                                      throws java.lang.Exception
Template method that handles @ResponseStatus annotation.

Default implementation send a response error using HttpServletResponse.sendError(int), or HttpServletResponse.sendError(int, String) if the annotation has a reason. Returns an empty ModelAndView.

Parameters:
responseStatus - the annotation
request - current HTTP request
response - current HTTP response
handler - the executed handler, or null 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
Throws:
java.lang.Exception
