使用poi,做传统的excel导出,然后想在浏览器中,让用户选择另存为,保存用户下载的xls文件,这个时候,可能的是在ie下出现乱码(ie,9,10,11),但在firefox,chrome下没乱码,
因此必须综合判断,编写一个工具类:
/**
*
* @Title: processFileName
*
* @Description: ie,chrom,firfox下处理文件名显示乱码
*/
public static String processFileName(HttpServletRequest request, String fileNames) {
String codedfilename = null;
try {
String agent = request.getHeader("USER-AGENT");
if (null != agent && -1 != agent.indexOf("MSIE") || null != agent
&& -1 != agent.indexOf("Trident")) {// ie
String name = java.net.URLEncoder.encode(fileNames, "UTF8");
codedfilename = name;
} else if (null != agent && -1 != agent.indexOf("Mozilla")) {// 火狐,chrome等
codedfilename = new String(fileNames.getBytes("UTF-8"), "iso-8859-1");
}
} catch (Exception e) {
e.printStackTrace();
}
return codedfilename;
}
然后,
response.setHeader("Cache-Control", "private");
response.setHeader("Pragma", "private");
response.setContentType("application/vnd.ms-excel;charset=utf-8");
response.setHeader("Content-Type", "application/force-download");
title = FileUtil.processFileName(request, title);
response.setHeader("Content-disposition", "attachment;filename=" + title + ".xls");
就可以解决了,注意判断是否ie的时候,ie 11的agent是Trident
