Thanks for this blog, I ran into exactly the same problem and your solution works perfectly :-)

Also Luis’ enhancement was important too, otherwise the controller would have missed the request parameters like Luis mentioned.

For those of you who have moved to grails 1.1.1, the DSL definition for the spring bean looks like (in resource.groovy)

beans = {
multipartResolver(com.example.CustomMultipartResolver) {
maxUploadSize = 1048576
}
}

Wow, thanks for this post ! I extended your solution because I wanted for the controller to still receive request parameters, at least non file ones. It’s a dirty hack because commons-fileupload doesn’t provide the right extension points for doing this cleanly but it works quite well. I replace line 11 of your CustomMultipartResolver with the following lines:

String encoding = determineEncoding(request);
FileUpload fileUpload = newFileUpload(getFileItemFactory())
fileUpload.setHeaderEncoding(encoding)
def fileItems = ((ServletFileUpload)fileUpload).parseRequest(request);
def parsingResult = parseFileItems(fileItems, encoding)
return new DefaultMultipartHttpServletRequest(request, [:], parsingResult.multipartParameters)
