Excel导出文件名中文乱码问题

方案：使用 request.getHeader("USER-AGENT") 判断浏览器的类型

response.setContentType("application/msexcel");

String excfileName = "";

try {
  String agent = (request.getHeader("USER-AGENT")).toLowerCase();
  if (StringUtils.contains(agent, "mise")) {
    //IE浏览器
    excfileName = fileName;
    //excfileName = URLEncoder.encode(fileName,"UTF8");
  } else if (StringUtils.contains(agent, "chrome") || StringUtils.contains(agent, "firefox")) {
    //google,火狐浏览器
    excfileName = new String(fileName.getBytes("GB2312"), "ISO-8859-1");
  } else if (StringUtils.contains(agent, "safari")) {
    excfileName = new String(fileName.getBytes("UTF-8"), "ISO8859-1");
  } else {
    excfileName = URLEncoder.encode(fileName, "UTF8");
  }
} catch (UnsupportedEncodingException e) {
  log.error("encod chinese error ,now set En name", e);
  codedFileName = "waybill";
}
response.setHeader("Content-Disposition", "attachment;filename=" + excfileName + ".xls");
