Problems with MultipartFile Upload

[Mikhas]

Hey guys!

I'm trying to make an Annotation based upload controller... but with no success .

Spring is no finding the param with the file.

org.springframework.web.bind.MissingServletRequest ParameterException: Required org.springframework.web.multipart.MultipartFile parameter 'file' is not present

This is my upload method on my controller:

@RequestMapping("/painel.upload.do")
	public String upload(@RequestParam("file") MultipartFile file) {
		if (file == null) {
			System.out.println("OH NO");
		} else {
			System.out.println("Yes!");
		}
		return "painel.lista";
	}

And my Upload form:

<form method="POST" enctype="multipart/form-data" action="painel.upload.do">
		<fieldset>
			<legend>Upload Painel</legend>
			<table>
				<tr>
					<td>
						<label>Arquivo:</label>
					</td>
					<td>
						<input type="file" name="file" />
					</td>				
				</tr>
				<tr>
					<td colspan="2">
						<input type="submit" />
					</td>
				</tr>
			</table>
		</fieldset>
	</form>

Is there soething missing?


Thanks guys

post your entire controller. I have a feeling you didnt create an instance of file on the controllers "get" handler method.

I've had the same issue, see my post here:

In my case it was enough to add a CommonsMultipartResolver bean to my appliationContext.xml

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