关于java文件下载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：

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：
