问题描述
我试图将数据从excel导入到db表中，当我用邮递员测试该应用程序时，它成功了，但是excel表上没有数据持久化到db表中。 Json响应还通过返回一个空数据对象来确认这一点。请协助。
以下是空但成功的json响应：
{
"status": "OK","success": true,"errorCode": 0,"data": [],"message": "See Data object for Details!","timestamp": "2020-08-25T13:27:36.112+00:00"
}
这是我的导入代码段
@Transactional
public List <AuditorStampDutyReport> importAuditorStampDutyReportDetails(multipartfile myfile) {
List<AuditorStampDutyReport> uploadReport = new ArrayList<>();
AuditorStampDutyReport excelReport = new AuditorStampDutyReport();
int sheetNumber=1,rowNumber=2;
try {
Workbook workbook = new XSSFWorkbook(myfile.getInputStream());
for (int i = 2; i < workbook.getNumberOfSheets(); i++) {
sheetNumber = i;
Sheet sheet = workbook.getSheetAt(i);
for (Row row : sheet) {
rowNumber = row.getRowNum();
if (rowNumber < 2) {
String possibleTaxPayerId = ImportExcelHelper.getorDefault(row.getCell(1),"").trim().replaceAll(" +"," ");
Organization organization = null;
//for name of tax payer
if (possibleTaxPayerId != null) {
organization = organizationRepository.findFirstNameByNameLike(organization.getId(),possibleTaxPayerId);
}
excelReport.setorganization(organization);
excelReport.setTin_of_tax_payer_organization(ImportExcelHelper.getString(row.getCell(2)));
excelReport.setPeriod_covered(ImportExcelHelper.getorDefault(row.getCell(3),""));
continue;
}
if (rowNumber > 2 && rowNumber < 6){
excelReport.setDate_of_transaction(ImportExcelHelper.getDate(row.getCell(2)));
excelReport.setDuty_payer(ImportExcelHelper.getString(row.getCell(3)));
excelReport.setTin_of_duty_payer(ImportExcelHelper.getString(row.getCell(4)));
String possibleInstrumentId = ImportExcelHelper.getorDefault(row.getCell(5),"");
Instruments instruments = null;
if (possibleInstrumentId != null) {
instruments = instrumentsRepository.findByNameLike(instruments.getId(),possibleInstrumentId);
}
excelReport.setInstruments(instruments);
excelReport.setAssessment_number(ImportExcelHelper.getLong(row.getCell(6)));
DeedOfAssignment deedOfAssignment = null;
if(deedOfAssignment.getId()!=null && deedOfAssignment.getId()>0) {
}
}
}
excelReport.setReceipt_number(ImportExcelHelper.getString(row.getCell(10)));
excelReport.setConsideration(ImportExcelHelper.getDouble(row.getCell(11)));
excelReport.setRate(ImportExcelHelper.getDouble(row.getCell(12)));
excelReport.setAmount_payable(ImportExcelHelper.getDouble(row.getCell(13)));
excelReport.setAmount_paid(ImportExcelHelper.getDouble(row.getCell(14)));
excelReport.setDate_of_payment(ImportExcelHelper.getDate(row.getCell(15)));
excelReport.setBalance(ImportExcelHelper.getDouble(row.getCell(16)));
excelReport.setPenalty(ImportExcelHelper.getDouble(row.getCell(17)));
excelReport.setoutstanding(ImportExcelHelper.getDouble(row.getCell(18)));
excelReport.setRemarks(ImportExcelHelper.getString(row.getCell(19)));
if (ImportExcelHelper.isCellEmpty(row.getCell(0))) {
continue; //Empty END OF FILE
}
if(rowNumber==16){
excelReport.setAmount_recoverable(ImportExcelHelper.getDouble(row.getCell(18)));
}
logger.log(Level.INFO,"Row Number: {0}",rowNumber);
uploadReport.add(excelReport);
}
}
uploadReport = auditorStampDutyReportRepository.saveAll(uploadReport);
}
catch (IOException| IllegalArgumentException | NullPointerException ex) {
logger.log(Level.SEVERE,null,ex);
throw new IllegalArgumentException("Sheet: " + (sheetNumber + 1) + " - Row: " + (rowNumber) + " - Error: " + ex.getMessage());
}
return uploadReport;
}
这是excel助手类：

}
}
public static LocalDate getDate(String date) {
DateTimeFormatter formatter = new DateTimeFormatterBuilder()
.appendOptional(DateTimeFormatter.ofPattern("d/MM/yyyy"))
.appendOptional(DateTimeFormatter.ofPattern("d/M/yyyy"))
.appendOptional(DateTimeFormatter.ofPattern("dd/M/yyyy"))
.appendOptional(DateTimeFormatter.ofPattern("dd/MM/yyyy"))
.toFormatter();
return LocalDate.parse(date,formatter);
}
}
这是我的控制器
@Transactional
@PostMapping(path = "/upload",consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
public ResponseEntity<Object> uploadAuditorReport(@RequestPart("importFile") multipartfile fileImport){
System.out.println("Entry Point With File Import : " + fileImport.getName());
List <AuditorStampDutyReport> uploadExcelSheet = auditorStampDutyReportService.importAuditorStampDutyReportDetails(fileImport);
return ResponseEntity.ok(new JsonResponse("See Data object for Details!",uploadExcelSheet));
}
