How to catch "org.springframework.web.multipart.MultipartException" in Grails 3

Question

I'm having an awfully hard time catching the error: org.springframework.web.multipart.MultipartException

I have the following code:

final class UploadTextCommand  {
   MultipartFile contents
   static constraints = {
   }
}

Additionally to handle the post of the file I have this action:

def upload = { UploadTextCommand -> 
   ...code...
}

I've got these settings in the "application.yml" file to force the error:

controllers:
    upload:
        maxFileSize: 100
        maxRequestSize: 100

So I can reliably recreate the exception, but I can't catch it before the browser shows a horrible view:

HTTP Status 500 - Request processing failed; 
nested exception is org.springframework.web.multipart.MultipartException

Please tell me how to catch this error in Grails. Just using a try/catch in the upload action fails miserably.

Could you show verbose stacktrace of this error? – Michal_Szulc Mar 19 '16 at 23:37 — Michal_Szulc, Mar 19 '16 at 23:37
@MichalSzulc I've added the stacktrace. – Aslan Brooke Mar 20 '16 at 00:53 — Aslan Brooke, Mar 20 '16 at 00:53

You can find in a stacktrace:

the request was rejected because its size (318635) exceeds the configured maximum (100000)

and in your code:

controllers:
    upload:
        maxFileSize: 100
        maxRequestSize: 100

you should exceed maxFileSize, but if you want to handle exception check this solution. IMHO cleaner solution would be implementation of your own before filter or interceptor.
