　　服务器端代码：

@RequestMapping(“/test/uploadFile")
public ModelAndView saveUpload(
@RequestParam("uploadFile") MultipartFile file,
 HttpServletRequest request)
{
        String dir =request.getSession().getServetContext().getRealPath("uploadDir");
        File newPath = new File(dir +"saveFileName.zip");
        file.transferTo(newPath);      
}
