Method Details

setExceptionResolvers

public void setExceptionResolvers(List<HandlerExceptionResolver> exceptionResolvers)

Set the list of exception resolvers to delegate to.

getExceptionResolvers

public List<HandlerExceptionResolver> getExceptionResolvers()

Return the list of exception resolvers to delegate to.

setOrder

public void setOrder(int order)

getOrder

public int getOrder()

Description copied from interface: Ordered

Get the order value of this object.

Higher values are interpreted as lower priority. As a consequence, the object with the lowest value has the highest priority (somewhat analogous to Servlet load-on-startup values).

Same order values will result in arbitrary sort positions for the affected objects.

Specified by:

getOrder in interface Ordered

Returns:

the order value

• Ordered.LOWEST_PRECEDENCE

resolveException

public @Nullable ModelAndView resolveException(HttpServletRequest request,
 HttpServletResponse response,
 @Nullable Object handler,
 Exception ex)

Resolve the exception by iterating over the list of configured exception resolvers.

The first one to return a ModelAndView wins. Otherwise null is returned.

Specified by:

resolveException in interface HandlerExceptionResolver

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 in the resolution chain
