I am developping an single page app with angularjs and Spring Mcv Rest.
I am calling my service (mail sending with javax mail) like that in Angularjs : SendProformaFax.get({idCommande:$scope.commande.id})
And on server side my service :
@RequestMapping(value = "/sendProformaFax/{idCommande}",
method = RequestMethod.GET,
produces = MediaType.APPLICATION_JSON_VALUE)
@Timed
public void imprimeProforma(@PathVariable String idCommande) {
Commande commande = commandeRepository.findOne(new Long(idCommande));
List<Vente> ventes = venteRepository.findAllByCommande(commande);
blService.sendProformaFax(ventes);
}
I would like to display a message when the function sendProformaFax throws a MessagingException.
I don't know how to return this exception in my RestController and how to catch it in Angularjs.
If anyone can help me on this...
Thanks.
EDIT :
On server side I am doing this :
@ExceptionHandler(value = Exception.class)
public ErrorView defaultErrorHandler(HttpServletRequest req, Exception e) throws Exception {
// If the exception is annotated with @ResponseStatus rethrow it and let
// the framework handle it - like the OrderNotFoundException example
// at the start of this post.
// AnnotationUtils is a Spring Framework utility class.
if (AnnotationUtils.findAnnotation(e.getClass(), ResponseStatus.class) != null)
throw e;
// Otherwise setup and send the user to a default error-view.
ErrorView mav = new ErrorView();
mav.setException(e.getMessage());
mav.setUrl(req.getRequestURL().toString());
mav.setMessage("Veuillez contacter le support informatique.");
return mav;
}
On Angularjs side I am doing this
CreateFichierCiel.get({params:param}, function (response) {
$scope.infoMessage = "La génération du fichier CIEL est terminée."
$activityIndicator.stopAnimating();
$("#messageModal").modal('show');
$scope.find();
}, function (reason) {
$("#errorModal").modal('show');
})
But 'reason' object is like this :
config: Object data: Object error: "Internal Server Error" exception:
"java.lang.NullPointerException" message: "No message available" path:
"/api/createFichierCiel/15-00005" status: 500 timestamp: 1438430232307
proto: Object headers: function (name) { status: 500 statusText:
"Internal Server Error" proto: Object
So I am not getting the ErrorView class sent from the server.
If anyone can see where I am wrong here...
Thanks
You can make ExceptionHandler for MessagingException and set HTTPStatus to indicate that response has an error (egz. BAD_REQUEST)
@ExceptionHandler(MessagingException.class)
@ResponseStatus(HTTPStatus.BAD_REQUEST)
@ResponseBody
public ErrorView handleMessagingException(MessagingException ex) {
// do something with exception and return view
}
In AngularJS you can catch it from resource service like this:
MessagingService.get({idCommande: 1}, function (data) {
// this is success
}, function (reason) {
// this is failure, you can check if this is a BAD_REQUEST and parse response from exception handler
};
It almost the same when you use $http.
Adding to the answer by kTT, starting with Spring 4 you can wrap your @ExceptionHandler method in a class annotated with @ControllerAdvice so that you will have the same message for the same type of exception across the whole application. More you can look here
That is how I did it, we are using spring mvc and angularjs in our project.
I have this controllerAdvice class
@ControllerAdvice
public class ExceptionControllerAdvice {
@ExceptionHandler(ServiceException.class)
public ResponseEntity<ErrorResponse> rulesForCustomerNotFound(HttpServletRequest req, ServiceException e)
{
ErrorResponse error = new ErrorResponse();
error.portalErrorCode = e.getExceptionCode();
error.message = e.getMessage();
return new ResponseEntity<ErrorResponse>(error, HttpStatus.NOT_FOUND);
}
}
class ErrorResponse {
public int portalErrorCode;
public String message;
}
and then in restful controller where ServiceException is a customized runnable exception:
@Override
@RequestMapping("/getControls/{entity}")
public List<Control> getControls(@PathVariable(value="entity") String entity) throws ServiceException {
List<Control> controls = ImmutableList.of();
try {
controls = dao.selectControls(entity);
} catch (Exception e) {
logger.error("getting list of controls encountered an error ", e);
throw new ServiceException(50, "getting list of controls encountered an error.");
}
return controls;
}
in my app.js file in angularjs I use
.config(['$httpProvider', function ($httpProvider) {
$httpProvider.interceptors.push(function ($q, $location) {
return {
'response': function (response) {
//Will only be called for HTTP up to 300
return response;
},
'responseError': function (rejection) {
if(rejection.status === 0) {
alert('There is a problem connecting to the server. Is the server probably down?!');
}
else {
$location.url('/error').search({rejection: rejection});
}
return $q.reject(rejection);
}
};
});
}])
and in a error.controller.js
function init() {
ctrl.rejection = $location.search().rejection;
ctrl.portalErrorCode = ctrl.rejection.data.portalErrorCode;
ctrl.errorMessage = ctrl.rejection.data.message;
$log.info('An error occured while trying to make an ajax call' + ctrl.errorMessage + ': ' + ctrl.portalErrorCode);
}
and of course in error.tpl.html
<h2>
{{ctrl.rejection.status}} {{ctrl.rejection.statusText}}
</h2>
<h3 class="error-details">
Sorry, an error has occurred!
</h3>
<h3 class="error-details">
{{ctrl.errorMessage}}
</h3>
