EasyExcel导出多个文件并直接打包成zip下载

String zipName = "xxx.zip";
 try {
     response.addHeader("Content-Disposition", "attachment;filename=" + URLEncoder.encode(zipName, "UTF-8"));
     response.setContentType("application/vnd.ms-excel");
     
     // 准备zip输出流
     ZipOutputStream zos = new ZipOutputStream(response.getOutputStream());
     ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
     
     // 循环导出多个xlsx文件
     for (...) {
         
         // 准备zip对象
         ZipEntry entry = new ZipEntry("*文件名*" + ".xlsx");
         zos.putNextEntry(entry);
         
         // 准备填充模板的对象
         ExcelWriter build = EasyExcel.write(byteArrayOutputStream)
             .withTemplate(new ClassPathResource("*模板路径*").getInputStream()).build();
         
         // 修改换行规则为每填充一行后插入一个空行
         FillConfig fillConfig = FillConfig.builder().forceNewRow(Boolean.TRUE).build();
         
         WriteSheet sheet0 = EasyExcel.writerSheet(0).build();
         build.fill("*数据集合1*", sheet0);
         build.fill("*数据集合2*", fillConfig, sheet0);
         ...
         
         // 单个文件完成
         build.finish();
         
         // 添加到zip输出流中
         zos.write(byteArrayOutputStream.toByteArray());
         byteArrayOutputStream.reset();
     }
     zos.flush();
     zos.close();
 } catch (Exception e) {
     e.printStackTrace();
 }
