Interface HandlerExceptionResolver

All Known Implementing Classes:

AbstractHandlerExceptionResolver, AbstractHandlerMethodExceptionResolver, DefaultHandlerExceptionResolver, ExceptionHandlerExceptionResolver, HandlerExceptionResolverComposite, ResponseStatusExceptionResolver, SimpleMappingExceptionResolver

public interface HandlerExceptionResolver

Interface to be implemented by objects that can resolve exceptions thrown during handler mapping or execution, in the typical case to error views. Implementors are typically registered as beans in the application context.

Error views are analogous to JSP error pages but can be used with any kind of exception including any checked exception, with potentially fine-grained mappings for specific handlers.

Try to resolve the given exception that got thrown during handler execution, returning a ModelAndView that represents a specific error page if appropriate.

The returned ModelAndView may be empty to indicate that the exception has been resolved successfully but that no view should be rendered, for instance by setting a status code.

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
