springmvc 多文件上传 MultipartFile5

public String upload2(MultipartHttpServletRequest request, @RequestParam("name") String name){
List<MultipartFile> files = (List<MultipartFile>) request.getFile("myfiles");
}
//修改成如下方法，还是报同样下面的错误：
public String upload2(MultipartHttpServletRequest request, @RequestParam("name") String name, // 页面上的控件值
			@RequestParam MultipartFile[] myfiles) {
List<MultipartFile> files = Arrays.asList(myfiles);
}
// jsp页面，传一个myfiles，单个文件是可以通过的，

<form method="POST" action="multipartFileUpload.action"
		enctype="multipart/form-data">
		<input type="text" name="name" /><br> 
		<input type="file"name="myfiles" /><br>
		<input type="file"name="myfiles" /><br>
		<input type="submit" /><br>
	</form>

报错：

你的spring和commons-fileupload版本是多少。

我使用spring3.2.2 commons-fileupload:1.2.2没有问题

<input type="file"name="myfiles" /><br>
<input type="file"name="myfiles" /><br>

上面的name改成不一样试试，然后代码里边
MultipartFile file1 = (MultipartFile) request.getFile("myfiles");
MultipartFile file2 = (MultipartFile) request.getFile("myfiles2");

这样子试试。
