*/
@GetMapping("/default/excel/example")
public void defaultBuild(HttpServletResponse response) throws Exception {
List<ArtCrowd> dataList = this.getDataList();
Workbook workbook = DefaultExcelBuilder.of(ArtCrowd.class)
.build(dataList);
AttachmentExportUtil.export(workbook, "艺术生信息", response);
// 加密导出 AttachmentExportUtil.encryptExport(workbook, "艺术生信息", response,"123456");
