后端代码基于springmvc

/**
 * 上传图片公共Controller
 * @author 瘸子
 * @qq 1026290752
 *
 */
@Controller
public class UpdatePhonoController {


    @RequestMapping("/admin/uplode/photo")
    @ResponseBody
    public Map updatePhoto(HttpServletRequest request,HttpServletResponse response,@RequestParam("myFile") MultipartFile myFile){
        Map json = new HashMap();
        try {
            //输出文件后缀名称
            System.out.println(myFile.getOriginalFilename());
            DateFormat df = new SimpleDateFormat("yyyyMMddHHmmssSSS");
            //图片名称
            String name = df.format(new Date());

            Random r = new Random();
            for(int i = 0 ;i<3 ;i++){
                name += r.nextInt(10);
            }
            //
            String ext = FilenameUtils.getExtension(myFile.getOriginalFilename());
            //保存图片       File位置 （全路径）   /upload/fileName.jpg
            String url = request.getSession().getServletContext().getRealPath("/static/img/upload/phono/");
            //相对路径
            String path = "/"+name + "." + ext;
            File file = new File(url);
            if(!file.exists()){
                file.mkdirs();
            }
            myFile.transferTo(new File(url+path));
            json.put("success", "/static/img/upload/phono/"+path);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return json ;
