Posted 2020-08-06

// 判断浏览器类型，firefox浏览器做特殊处理，否则下载文件名乱码
	public static void compatibleFileName(HttpServletRequest request, HttpServletResponse response, String excelname) throws UnsupportedEncodingException {
		String agent = request.getHeader("USER-AGENT").toLowerCase();
		response.setContentType("application/vnd.ms-excel");
		String fileName = excelname;
		String codedFileName = java.net.URLEncoder.encode(fileName, "UTF-8");
		if (agent.contains("firefox")) {
			response.setCharacterEncoding("utf-8");
			response.setHeader("content-disposition", "attachment;filename=" + new String(fileName.getBytes(), "ISO8859-1") + ".xls");
		} else {
			response.setHeader("content-disposition", "attachment;filename=" + codedFileName + ".xls");
		}
