try {

//下面这句必须加，不然报错

MultipartResolver resolver = new CommonsMultipartResolver(hsq.getSession().getServletContext());

MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) hsq;

//获取一起跟文件传过来的其他参数值

String id = multipartRequest.getParameter("id");

//获取上传上来的文件

Map<String, MultipartFile> fileMap = multipartRequest.getFileMap();

for (Map.Entry<String, MultipartFile> entry : fileMap.entrySet()) {

MultipartFile file = entry.getValue();

String fileName = file.getOriginalFilename();

System.out.println(fileName);

String path = "C:\\Users\\user\\Desktop\\" + fileName;

file.transferTo(new File(path));

}

} catch (Exception e) {
