Method Detail

setOrder

public void setOrder(int order)

getOrder

public int getOrder()

Description copied from interface: Ordered

Return the order value of this object, with a higher value meaning greater in terms of sorting.

Normally starting with 0, with Integer.MAX_VALUE indicating the greatest value. Same order values will result in arbitrary positions for the affected objects.

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

Specified by:

getOrder in interface Ordered

Returns:

the order value

setExceptionResolvers

public void setExceptionResolvers(java.util.List<HandlerExceptionResolver> exceptionResolvers)

Set the list of exception resolvers to delegate to.

getExceptionResolvers

public java.util.List<HandlerExceptionResolver> getExceptionResolvers()

Return the list of exception resolvers to delegate to.

resolveException

public ModelAndView resolveException(HttpServletRequest request,
                                     HttpServletResponse response,
                                     java.lang.Object handler,
                                     java.lang.Exception ex)

Resolve the exception by iterating over the list of configured exception resolvers. The first one to return a ModelAndView instance 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
