Spring @ExceptionHandler - apply to json producing @RequestMapping only -

i have exception handler produce json error object consumed javascript in view.

@controlleradvice public class exceptionhandlercontroller {       @exceptionhandler(value = exception.class)     @responsebody     public final jsonresponse<void> handlejsonexception(             final exception e,             final httpservletrequest request,             final httpservletresponse response) {         response.setstatus(httpservletresponse.sc_internal_server_error);         return new errorjsonresponse(e);     }  } 

i don't want method run regular postback (non json) requests. have these sorts of exception handled web.xml configured error pages.

<error-page>     <error-code>500</error-code>     <location>/500</location> </error-page> 

in @requestmapping methods return json explicitly set produces value.

@requestmapping(value = "/dosomething",         method = requestmethod.post,         produces = mediatype.application_json_value) 

how can tell spring use particular exception handler based on produces content type?

@controlleradvice annotated classes assist known controllers in application. developers restrict exceptionhandlers cases using specific business/technical exceptions; in case, exception.class broad.

but use case valid - in fact, issue has been resolved (see spr-10222) upcoming spring 4.0 release.

you example have restexceptionhandlercontroller annotated @controlleradvice(annotations = restcontroller.class) - given rest controllers annotated @restcontroller (annotation implies @responsebody on methods!).

however, new feature doesn't rely on mediatypes (negotiated @ runtime, depending on client's request) on annotations, assignabletypes, packages, base package classes... think structure @controlleradvice annotated classes.
