Java代码      ...Controller...{        //创建一个通用的多部分解析器.     CommonsMultipartResolver commonsMultipartResolver = new   CommonsMultipartResolver(request.getSession().getServletContext());  //设置编码     commonsMultipartResolver.setDefaultEncoding(”utf-8″);   //判断 request 是否有文件上传,即多部分请求...   if (commonsMultipartResolver.isMultipart(request))     {        //转换成多部分request        MultipartHttpServletRequest multipartRequest =             commonsMultipartResolver.resolveMultipart(request);        // file 是指 文件上传标签的 name=值      // 根据 name 获取上传的文件...      MultipartFile file = multipartRequest.getFile("file");          //上传后记录的文件...         File imageFile = new File("fileName");      //上传...      file.transferTo(imageFile);         }    }
