Question

我尝试将文件上传到文件夹中，文件路径的值从ajax调用成功传递给控制器类，但在这个类上我收到错误：

当前请求不是多部分请求

这是我的代码：

 @RequestMapping(value = "/event/uploadFile",headers=("content-type=multipart/*"), 
 method = RequestMethod.POST,consumes ={"application/x-www-form-urlencoded"})
    //String quote_upload=C:\fakepath\images.jpg    public @ResponseBody
    String uploadFileHandler(           @RequestParam String name,
            @RequestParam MultipartFile file) { 
            System.out.println("Creating the directory to store file");

            if (!file.isEmpty()) {          try {
            byte[] bytes = file.getBytes();

            // Creating the directory to store file
            String rootPath = "C://apache-tomcat-7.0.73//upload";
            File dir = new File(rootPath + File.separator + "tmpFiles");
            if (!dir.exists())
                dir.mkdirs();

            // Create the file on server
            File serverFile = new File(dir.getAbsolutePath()
                    + File.separator);
            BufferedOutputStream stream = new BufferedOutputStream(
                    new FileOutputStream(serverFile));
            stream.write(bytes);
            stream.close();

            System.out.println("************Server File Location="
                    + serverFile.getAbsolutePath());

            //return "You successfully uploaded file=" + name;          } catch (Exception e) {
            System.out.println("************failes");
            //return "You failed to upload " + name + " => " + e.getMessage();          }           //return "You failed to upload " + name
                //+ " because the file was empty.";         }       System.out.println("hello");        return "hello";     }

我的Ajax代码是：

$.ajax({ 
type : 'POST', url :"<c:url value='/event/uploadFile'/>",   
data:{name: $("#quote_name").val(), 
file:$("#quote_upload").val()}, 
//cache: false,
//contentType:text/plain, 
// processData: false, 
//dataType : "json", 
//Contenttype: 
})

这是我的控制器类代码，当我运行项目时出现此错误：
