    Actually resolve the given exception that got thrown during 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.

    Handle the case where an @ModelAttribute method argument has binding or validation errors and is not followed by another method argument of type BindingResult.
    By default, an HTTP 400 error is sent back to the client.
    参数:
    request - current HTTP request
    response - current HTTP response
    handler - the executed handler
    返回:
    an empty ModelAndView indicating the exception was handled

```
    Handle the case where no handler was found during the dispatch.
    The default implementation sends an HTTP 404 error and returns an empty ModelAndView. Alternatively, a fallback view could be chosen, or the NoHandlerFoundException could be rethrown as-is.
    参数:
    ex - the NoHandlerFoundException to be handled
    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)

    an empty ModelAndView indicating the exception was handled

```
    Handle the case where an async request timed out.
    The default implementation sends an HTTP 503 error.
    参数:
    ex - the AsyncRequestTimeoutExceptionto be handled
    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)
