注意将页面的编码转成iso-8859-1：
public void service(IRequestCycle cycle) throws UnsupportedEncodingException { String filePath = cycle.getParameter("file"); File file = new File(filePath); String filename = cycle.getParameter("filename"); String encode = cycle.getParameter("encode"); if (StringUtils.isEmpty(encode)) { encode = "false"; } String sfjm = cycle.getParameter("sfjm"); if (StringUtils.isEmpty(sfjm)) { sfjm = "false"; } if (filename == null || filename.equals("")) { filename = file.getName(); } else { if (encode.equalsIgnoreCase("true")&&sfjm.equalsIgnoreCase("true")) { filename = Base64.decode_eps(filename); filename = encodingFileName(filename); log.info("=========download.svc==========Base64.decode_eps(filename)=" + filename); } else if (encode.equalsIgnoreCase("utf8")&&sfjm.equalsIgnoreCase("true")) { try { filename = new String(filename.getBytes("UTF-8"), "UTF-8"); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } } else { try { if (System.getProperty("file.separator").equalsIgnoreCase("/")) { filename = new String(filename.getBytes("gbk"), "iso-8859-1"); } else { filename=new String(filename.getBytes("ISO-8859-1"), "utf-8"); filename = new String(filename.getBytes(), "ISO-8859-1"); } } catch (UnsupportedEncodingException e) { e.printStackTrace(); } } } String type = cycle.getParameter("type"); if (type == null || type.equals("")) { type = "application/x-msdownload"; } OutputStream out = null; FileInputStream in = null; response.setContentType(type);
