关于java文件[下载][Link 1]文件名乱码问题解决方案  做为一名程序员，大家应该都遇到过乱码的问题吧！这篇文章是自己解决关于关于java文件下载文件名乱码问题的处理： String fileName = "下载的文件名"; String userAgent = request.getHeader("User-Agent");   
//针对IE或者以IE为内核的 [浏览器][Link 2] ：  
if (userAgent.contains("MSIE")||userAgent.contains("Trident")) \{   
fileName = java.net.URLEncoder.encode(fileName, "UTF-8");  
\} else \{   
//非IE浏览器的处理：  
fileName = new String(fileName.getBytes("UTF-8"),"ISO-8859-1");  
\}  
response.setHeader("Content-disposition", String.format("attachment; filename=\\"%s\\"", fileName));  
response.setContentType("application/vnd.ms-excel;charset=utf-8");  
response.setCharacterEncoding("UTF-8");   
  
这样子就可以了！ 顺便贴一下：各个浏览器关于request.getHeader("User-Agent"); 的输出内容： chrome : Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.154 Safari/537.36
