關於java文件下載文件名亂碼問題解決方案

做爲一名程序員，大家應該都遇到過亂碼的問題吧！這篇文章是自己解決關於關於java文件下載文件名亂碼問題的處理：

String fileName = "下載的文件名";

String userAgent = request.getHeader("User-Agent"); 
//針對IE或者以IE爲內核的瀏覽器：
if (userAgent.contains("MSIE")||userAgent.contains("Trident")) {
fileName = java.net.URLEncoder.encode(fileName, "UTF-8");
} else {
//非IE瀏覽器的處理：
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");

這樣子就可以了！

順便貼一下：各個瀏覽器關於request.getHeader("User-Agent"); 的輸出內容：
