在JQuery文件上传器中获取异常

Question

我是JQuery文件上传器的新手，我正在实现其中的一部分。当我从JQuery文件上传器中选择一个图像时，调用将转到服务器端（SpringController），但API返回：

406不可接受

这是我对服务器的调用：

$(this).fileupload({
        // Uncomment the following to send cross-domain cookies:
        //xhrFields: {withCredentials: true},
        url: uploadSettings.upload_url,
        type: 'POST',
        maxNumberOfFiles: uploadSettings.maxNumberOfFiles,
        maxFileSize: uploadSettings.maxFileSize,
        acceptFileTypes: uploadSettings.fileSelection,
        sequentialUploads: true,
        paramName:'uploadfiles[]',
        dataType: 'text'
    });

我的Java控制器代码如下：

@RequestMapping(value = { "/user/fileuploader" }, method = RequestMethod.POST, 
produces = "text/plain")


@ResponseBody public String uploadFileHandler(
@RequestParam("uploadfiles[]") MultipartFile[] file,
HttpServletRequest request, HttpServletResponse response) {

有什么建议？
