Controller实现

@RequestMapping(value = "upload",method = RequestMethod.POST)
    public String  uploadFile(HttpServletRequest request, MultipartFile upload){
        try {
            String path = request.getSession().getServletContext().getRealPath("/uploads/");
            //判断该路径是否存在
            File file = new File(path);
            if (!file.exists()) {
                file.mkdirs();
            }

            //上传文件项
            String filename = upload.getOriginalFilename();
            String saveName = filename.substring(filename.lastIndexOf(File.separator) + 1);
            upload.transferTo(new File(path, saveName));

            //Thread t = new LogToSqlThread(fileName,uploadPath,savePath);
            //t.start();
            return "upload success";
        } catch(Exception e) {
            return e.toString();
        }
    }
