java导出excel文件名称乱码问题解决

用下面这种方式，ie，chrome没问题，但是safari有问题

private static OutputStream getOutputStream(String fileName, HttpServletResponse response) throws Exception {

    response.setContentType("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");

    response.setCharacterEncoding("utf8");

    response.setHeader("Content-Disposition","attachment;filename="+fileName+".xlsx");

    response.addHeader("Access-Control-Expose-Headers","Content-disposition");

       return response.getOutputStream();

}

用下面这种方式在ie，chrome，safari浏览器下都是ok的，中文名称都能正常显示：

 private static OutputStream getOutputStream(String fileName, HttpServletResponse response) throws Exception {

        fileName = URLEncoder.encode(fileName, "UTF-8");

        response.setContentType("application/x-msdownload");

        response.setCharacterEncoding("iso-8859-1");

        response.setHeader("Content-Disposition", "attachment;filename*=UTF-8''" + fileName+".xlsx");

        response.addHeader("Access-Control-Expose-Headers","Content-disposition");

        return response.getOutputStream();

    }
