Tiny3结合webupload实现多文件上传.docx

Tiny3.0结合WebUpload实现多文件上传Tiny Framework是一个基于J2EE技术的应用开发框架，可以用来开发各种Java Application和Web Application。最近推出了3.0版，性能得到了很大提升，下面将Tiny3.0结合WebUpload插件实现文件上传的方法拿出来，请大家多指点。TinyUiEnterprise2已经集成了webupload插件，但是没有action后台的实现，经过本人的摸索和测试，实现了文件的上传功能，现把实现方法说明如下：首先在page页面文件中加入webupload插件，使用方法为#webUpload（saveurl），详细内容请查看TinyUiEnterprise2中对插件的介绍。如：#webUpload(multiupload?userId=admin)multiupload?userId=admin是调用的后台action处理的urlAction中的实现@RequestMapping(/multiupload)@ResponseBodypublic Map?, ? multiUpload(@RequestParam(webfile)TinyMultipartFile[] files,String userId,Model model) throws IOException{String ls_path=ConfigurationUtil.getConfigurationManager().getConfiguration(UPLOADPATH);String ls_filename=;String ls_filepath=;if(files!=null){for (inti = 0; i files.length; i++) {TinyMultipartFile file=files[i];if(file!=null){ls_filename = file.getOriginalFilename();ls_filename = /uploads/user/+userId+ls_filename.substring(ls_filename.indexOf(.));ls_filepath=ls_path + ls_filename;super.saveFile(ls_filepath, file);if(userId !=null){ SysUserDto sysUserDto = sysUserService.getSysUser(userId);if(sysUserDto!=null){sysUserDto.setRemark(ls_filename);sysUserService.updateSysUser(sysUserDto);model.addAttribute(sysUserDto,sysUserDto); } }}}}return resultMap(true,ls_filename);}TinyMultipartFile 是Tiny重新定义的文件类型；ConfigurationUtil.getConfigurationManager().getConfiguration(UPLOADPATH);用来获得在application.xml中设置的文件上传位置；action实现了根据参数userId，把上传的文件路径存放到数据库中的user表中，实现了user头像文件的上传功能，大家可以结合自己的情况进行修改。saveFile(ls_filepath, file)实现了上传文件写入的处理，具体实现如下：protectedvoid saveFile(String path, TinyMultipartFile file) {try { InputStream stream = file.getInputStream(); OutputStream bos = new FileOutputStream(path);intbytesRead = 0;byte[] buffer = newbyte[8192];while ( (bytesRead = stream.read(buffer, 0, 8192)) != -1) {bos.write(buffer, 0, bytesRead); }bos.close();stream.close();bos = null;stream = null; }catch (FileNotFoundException ex) { ; }catch (IOException ex) { ; }
