实现代码

public void export(HttpServletResponse response, HttpServletRequest request, ModelMap modelMap) {
    try {
        String fileName = "批量导出.zip";
        response.setContentType("application/octet-stream ");
        response.setHeader("Connection", "close"); // 表示不能用浏览器直接打开
        response.setHeader("Accept-Ranges", "bytes");// 告诉客户端允许断点续传多线程连接下载
        response.setHeader("Content-Disposition",
                    "attachment;filename=" + new String(fileName.getBytes("GB2312"), "ISO8859-1"));
        response.setCharacterEncoding("UTF-8");

        OutputStream out = response.getOutputStream();
        ZipOutputStream zos = new ZipOutputStream(out);

        //读取路径下的模板
        TemplateExportParams params = new TemplateExportParams("导出模板.xlsx");
        //获取业务数据逻辑
        List<HashMap<String, Object>> exportList = new ArrayList<>();

        //循环导出
        for (HashMap<String, Object> map : exportList) {
            //导出的文件名称
            String entryName = (String) map.get("title") + ".xlsx";
            ZipEntry entry = new ZipEntry(entryName);
            //easypoi导出excel文件
            Workbook workbook = ExcelExportUtil.exportExcel(params, map);
            //编写新的zip条目，并将流定位到条目数据的开头
            zos.putNextEntry(entry);
            //workBook.write会指定关闭数据流，直接用workbook.write(zos)，下次就会抛出zos已被关闭的异常，所以用ByteArrayOutputStream来拷贝一下。
            ByteArrayOutputStream bos = new ByteArrayOutputStream();
            //workbook写入bos
            workbook.write(bos);
            //bos写入zos
            bos.writeTo(zos);
            zos.closeEntry();
        }
        if(zos != null) {
            zos.flush();
            zos.close();
        }
    }
    catch (Exception e) {
        e.printStackTrace();
    }
}
