文件下载过程中,会出现中文名乱码或者文档名称中含有空格的,需要处理下,否则要么乱码,要么空格变成了“+”号,有点头疼。
临时想到一种办法:
即:
//定义输出文件编码及类型和文件名

/** * 查看附件 */ public
String view() { try
{ Attachment newAttach = attachService.getAttachment(attach.getId()); if
(attach != null) { try
{ InputStream inStream = new
FileInputStream(newAttach .getFilePath()); this.getResponse().reset(); this.getResponse().setContentType("bin"); this.getResponse().addHeader( "Content-Disposition", "attachment; filename=\"" + URLEncoder.encode(newAttach.getName(), "UTF-8").replace("+", "%20") + "\""); // 循环取出流中的数据 byte[] b = new
byte[512]; int
len; this.getResponse().getOutputStream().flush(); while
((len = inStream.read(b)) > 0) { this.getResponse().getOutputStream().write(b, 0, len); } inStream.close(); } catch
(FileNotFoundException e) { //e.printStackTrace(); this.sendMessage("error"); } catch
(IOException e) { this.sendMessage("error"); //e.printStackTrace(); } } } catch
(DAOException e) { e.printStackTrace(); this.addActionMessage(e.getMessage()); return
ERROR; } return
null; } |
这样,在UrlEncode 之后, 将 "+" 替换成 "%20",因为浏览器将%20转换为空格,这样又空格再转换回来,就不影响下载的文件名称了,呵呵!
