public class DefaultHandlerExceptionResolver
Default implementation of the HandlerExceptionResolver interface that resolves standard Spring exceptions and translates
them to corresponding HTTP status codes.
This exception resolver is enabled by default in the DispatcherServlet.

protected ModelAndView doResolveException(HttpServletRequest request,
HttpServletResponse response,
Object handler,
Exception ex)
AbstractHandlerExceptionResolverMay 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.
doResolveException in class AbstractHandlerExceptionResolverrequest - current HTTP requestresponse - current HTTP responsehandler - 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
null for default processing
protected ModelAndView handleNoSuchRequestHandlingMethod(NoSuchRequestHandlingMethodException ex,
HttpServletRequest request,
HttpServletResponse response,
Object handler)
throws IOException
The default implementation logs a warning, sends an HTTP 404 error, and returns
an empty ModelAndView. Alternatively, a fallback view could be chosen,
or the NoSuchRequestHandlingMethodException could be rethrown as-is.
ex - the NoSuchRequestHandlingMethodException to be handledrequest - current HTTP requestresponse - current HTTP responsehandler - the executed handler, or null if none chosen
at the time of the exception (for example, if multipart resolution failed)
IOException - potentially thrown from response.sendError()
protected ModelAndView handleHttpRequestMethodNotSupported(HttpRequestMethodNotSupportedException ex,
HttpServletRequest request,
HttpServletResponse response,
Object handler)
throws IOException
The default implementation logs a warning, sends an HTTP 405 error, sets the "Allow" header,
and returns an empty ModelAndView. Alternatively, a fallback view could be chosen,
or the HttpRequestMethodNotSupportedException could be rethrown as-is.
ex - the HttpRequestMethodNotSupportedException to be handledrequest - current HTTP requestresponse - current HTTP responsehandler - the executed handler, or null if none chosen
at the time of the exception (for example, if multipart resolution failed)
IOException - potentially thrown from response.sendError()
protected ModelAndView handleHttpMediaTypeNotSupported(HttpMediaTypeNotSupportedException ex,
HttpServletRequest request,
HttpServletResponse response,
Object handler)
throws IOException
The default implementation sends an HTTP 415 error,
sets the "Accept" header, and returns an empty ModelAndView. Alternatively, a fallback
view could be chosen, or the HttpMediaTypeNotSupportedException could be rethrown as-is.
ex - the HttpMediaTypeNotSupportedException to be handledrequest - current HTTP requestresponse - current HTTP responsehandler - the executed handler
IOException - potentially thrown from response.sendError()
protected ModelAndView handleHttpMediaTypeNotAcceptable(HttpMediaTypeNotAcceptableException ex,
HttpServletRequest request,
HttpServletResponse response,
Object handler)
throws IOException
Accept header.
The default implementation sends an HTTP 406 error and returns an empty ModelAndView.
Alternatively, a fallback view could be chosen, or the HttpMediaTypeNotAcceptableException
could be rethrown as-is.

IOException - potentially thrown from response.sendError()
protected ModelAndView handleMissingServletRequestParameter(MissingServletRequestParameterException ex,
HttpServletRequest request,
HttpServletResponse response,

throws IOException
The default implementation sends an HTTP 400 error, and returns an empty ModelAndView.
