[alibaba/easyexcel]模板填充导出的时候出现空指针异常

触发场景描述 web端点击触发后端代码,到了excelWriter.fill(new FillWrapper("data1", data),fillConfig,writeSheet);这里就直接报出空指针 触发Bug的代码

   String templateFileName = EasyExcelUtil.getPath() + "templates" + File.separator + "dome.xlsx";
            ExcelWriter excelWriter = EasyExcel.write("数据.xlsx").withTemplate(templateFileName).build();
            WriteSheet writeSheet = EasyExcel.writerSheet().build();
            FillConfig fillConfig= FillConfig.builder().direction(WriteDirectionEnum.HORIZONTAL).build();

            excelWriter.fill(new FillWrapper("data1", hourReports),fillConfig,writeSheet);
            excelWriter.fill(new FillWrapper("data1", hourReports),fillConfig,writeSheet);
            excelWriter.fill(new FillWrapper("data2", dayReportList), writeSheet);
            excelWriter.fill(new FillWrapper("data2", dayReportList), writeSheet);
            excelWriter.fill(new FillWrapper("data3", supplierReports), writeSheet);
            excelWriter.fill(new FillWrapper("data3", supplierReports), writeSheet);
            Map<String, Object> map = new HashMap<String, Object>();
            map.put("date", date);
            excelWriter.fill(map, writeSheet);

            // 别忘记关闭流
            excelWriter.finish();
