导致上述问题的原因主要是下载导出过程中,有的属性为空
主要解决问题的思路:
把空的属性转成化一下,如果是String转成 “”,Integer转成0
具体代码如下:

String establishedDate = company.getEstablishedDate() != null ? sdf.format(company.getEstablishedDate()) : "";
row.createCell(7).setCellValue(establishedDate);
String openedDate = company.getOpenedDate() != null ? sdf.format(company.getOpenedDate()) : "";
row.createCell(8).setCellValue(openedDate);
Integer staffNum = company.getStaffNum() == null ? 0 : company.getStaffNum();
row.createCell(9).setCellValue(staffNum);
