IE下载乱码解决

做个下载功能ie 的都乱码 查阅资料 ie 浏览器应该使用

java.net.URLEncoder.encode 进行加密

其他大多都是 （ENCODING = utf-8）

new String( excelName.getBytes(ENCODING), “ISO-8859-1”);

判断IE 一般

agent.indexOf(“MSIE”) != -1 即可

恶心的IE11 居然不按常理出牌

调试输出

Mozilla/5.0 (Windows NT 6.1; Win64; x64; Trident/7.0; rv:11.0) like Gecko

需这样判断

-1 != agent.indexOf(“like Gecko”)

//判断浏览器 解决ie 文件名下载乱码
HttpServletRequest request =((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
String agent = request.getHeader("User-Agent");
boolean isMSIE = ((agent != null && agent.indexOf("MSIE") != -1 ) || ( null != agent && -1 != agent.indexOf("like Gecko")));    //判断版本,后边是判断IE11的
if(isMSIE){
excelName = java.net.URLEncoder.encode(excelName,ENCODING);
}else{
excelName = new String( excelName.getBytes(ENCODING), "ISO-8859-1");
}
response.setHeader("content-disposition", "attachment; filename="
+ excelName);// 设定输出文件头
response.setContentType("application/msexcel");// 定义输出类型
response.setCharacterEncoding(ENCODING);
sos = response.getOutputStream();
wb.write(sos);
sos.flush();
