java导出excel文件名乱码问题

一、解决方案:使用url编码

response.addHeader("Content-Disposition", URLEncoder.encode(fileName, "utf-8")   ".xlsx");

全部代码：

    private static void write(HttpServletResponse response, SXSSFWorkbook book, String fileName) throws IOException {
        response.setContentType("application/vnd.ms-excel;charset=UTF-8");
        response.setCharacterEncoding("UTF-8");
        response.addHeader("Content-Disposition", URLEncoder.encode(fileName, "utf-8")   ".xlsx");
        ServletOutputStream out = response.getOutputStream();
        book.write(out);
        out.flush();
        out.close();
    }
