我正在使用Spring MVC，这是我的方法：

/**
* Upload single file using Spring Controller.
*/
@RequestMapping(value = "/uploadFile", method = RequestMethod.POST)
public @ResponseBody ResponseEntity<GenericResponseVO<? extends IServiceVO>> uploadFileHandler(
            @RequestParam("name") String name,
            @RequestParam("file") MultipartFile file,
            HttpServletRequest request,
            HttpServletResponse response) {
    if (!file.isEmpty()) {
        try {
            byte[] bytes = file.getBytes();
            // Creating the directory to store file
            String rootPath = System.getProperty("catalina.home");
            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());
            return null;
        } catch (Exception e) {
            return null;
        }
    }
}
