Multipart upload using annotations

[m00sey]

I am trying to do a multipart file upload.

I am annotating my controller with

Controller, RequestMapping and RequestParam

annotations. ( I would have put the atSigns's in there but apparently that means I am linking to another site outside of the forum, and I can't do that until I have posted 5 times, seems like a bug to me, but that's an aside)

When the form is submitted I receive missing parameter exceptions, if I removed the enctype from the form, they resolve, but I lose the multipart file.

<form action="uploadSubmit.view" enctype="multipart/form-data" method="POST">

I have a multipart resolver declared in my applicationContext

<bean id="multipartResolver"
    class="org.springframework.web.multipart.commons.CommonsMultipartResolver"/>

The controller looks like this

Controller
public class UploadDestUrlReportController {

	RequestMapping("/upload.view")
	public ModelAndView handleUrlReport() {
//do stuff
		return new ModelAndView("upload", modelMap);
	}

	RequestMapping("/uploadSubmit.view")
	public ModelAndView handleUrlReportUpload(HttpServletResponse response,
			RequestParam("id") int id,
			RequestParam("id2") int id2,
			RequestParam("file") MultipartFile f) throws IOException {
		Map<String, Object> modelMap = new HashMap<String, Object>();
		if (f == null) {
			modelMap.put("msg", "null file");
			return new ModelAndView("upload", modelMap);
		}
		modelMap.put("msg", "File ( " + f.getName() + ") uploaded");
		return new ModelAndView("upload", modelMap);
	}

}

Any ideas on what I could be missing?

Thanks,

I am sure you figured this out by now, but I will reply anyway, just in case :-)

In the controller:

@RequestMapping(value="/upload.view")
public ModelAndView upload(HttpServletRequest request, HttpServletResponse response, @RequestParam("file") MultipartFile f) {
if (f == null) {
return new ModelAndView("upload", "msg", "The file is null.");
}

return new ModelAndView("upload", "msg", "File ( " + f.getOriginalFilename() + ") successfully uploaded.");
}

And in the appliction context:

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.C ommonsMultipartResolver">
<!-- Max size in bytes. -->
<property name="maxUploadSize" value="100000"/>
</bean>

In my implementation, this is all I needed. Hope this helps.
