触发场景描述

因wps需要登录才能操作,因此换了 onlyoffice, 结果无法导出且报错空指针异常 同样代码换回wps不存在这个问题,可以正常导出不会报空指针异常

触发Bug的代码

  excelWriter.finish(),   具体报错信息在这个方法内部 ctWorksheet.getDimension() 获取时对象为null.

private ResponseEntity<?> export(HttpServletResponse response, InputStream templateIs, List dataList) { ExcelWriter excelWriter = null; String filename = System.currentTimeMillis() + ".xlsx"; try { OutputStream outputStream = response.getOutputStream(); excelWriter = EasyExcel.write(outputStream).withTemplate(templateIs).build(); WriteSheet writeSheet = EasyExcel.writerSheet().build(); excelWriter.fill(dataList, writeSheet); } catch (IOException e) { e.printStackTrace(); } finally { // 关闭流 excelWriter.finish(); try { templateIs.close(); } catch (IOException e) { e.printStackTrace(); } }

感觉像是软件兼容问题，读可以读吗？ 读都不行的话，用poi读，保存为标准 .xlsx 格式再试试？

BinQSS commented 2 months ago

问题已经解决. 是属于软件兼容问题. 具体解决思路是. 用项目中已经存在且能正常导出的excel模板,复制并修改其中模板内容.已这个模板作为新模板使用. 当项目中.xlsx文件版本比较老的时候, 如果是通过onlyoffice 或者 wps 新建的 .xlsx 又会出现这种问题. 这个bug 能修复最好.
