Trying to upload MultipartFile with postman

I am trying to upload a Multipart File using PostMan and getting errors. Here is the code and screenshots:

@RequestMapping(value = "/upload", method = RequestMethod.POST)
public void uploadFileHandler(@RequestParam("name") String name,
        @RequestParam("name") MultipartFile file) {

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

            // Creating the directory to store file
            //String rootPath = System.getProperty("catalina.home");
            String rootPath = "C:\\Desktop\\uploads";
            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 + name);
            BufferedOutputStream stream = new BufferedOutputStream(
                    new FileOutputStream(serverFile));
            stream.write(bytes);
            stream.close();

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

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

You should have a thing like this:

@RequestMapping(value = "/upload", method = RequestMethod.POST, consumes = "multipart/form-data")
    public void uploadFileHandler(@RequestParam("name") String name,
                                  @RequestParam("file") MultipartFile file) {

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

                // Creating the directory to store file
                //String rootPath = System.getProperty("catalina.home");
                String rootPath = "C:\\Users\\mworkman02\\Desktop\\uploads";
                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 + name);
                BufferedOutputStream stream = new BufferedOutputStream(
                        new FileOutputStream(serverFile));
                stream.write(bytes);
                stream.close();

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

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

Please pay attention to consumes = "multipart/form-data". It is necessary for your uploaded file because you should have a multipart call. You should have @RequestParam("file") MultipartFile file instead of @RequestParam("name") MultipartFile file).

Of course you should have configured a multipartview resolver the built-in support for apache-commons file upload and native servlet 3.
