使用CommonsMultipartFile接收
@RequestMapping(method = RequestMethod.POST) public Result addFile(@RequestParam("file") CommonsMultipartFile file)throws IOException{ Attach resultData = attachService.saveFile(file).getResultData(); return ResultUtil.buildSuccess(resultData); }
service
@Override public Result<Attach> saveFile(CommonsMultipartFile file) { Attach attach = null; //根据系统时间插入 long filetime = System.currentTimeMillis(); Instant instant = Instant.ofEpochMilli(filetime); String format = DateUtil.format(Date.from(instant), YT_DYEART); try { Attach ar=new Attach(); //所在文件夹 String path="/upload/"+format+"/"; //文件全路径 String filte=path+filetime+file.getOriginalFilename(); File newFile=new File(filte); if(!newFile.exists()){ newFile.mkdirs(); } //原文件名 String orgName = file.getOriginalFilename(); //修改后的文件名 String name = filetime + file.getOriginalFilename(); //附件大小 long size = file.getFileItem().getSize(); //后缀 String suffixName = file.getOriginalFilename().substring(file.getOriginalFilename().lastIndexOf(".") ); //拷贝 spring封装方法 相当于上传 file.transferTo(newFile); } catch (IOException e) { logger.error("AttachServiceImpl.saveInsertAttach", e); return null; } return ResultUtil.buildSuccess(attach); }
