使用API​​创建xlsx文件

Question

当我尝试使用usig XSSF工作簿创建xlsx文件时，发生以下错误。我已经为人们看到了更多的答案，但是其中没有一个针对我的问题的答案。

我的代码的一小段处理了这个问题（这是导致错误的直接原因）：

public static void Reader(File file) throws IOException, InvalidFormatException {

    FileInputStream fis = new FileInputStream(file);

    // Creating a Workbook from an Excel file (.xlsx)
    XSSFWorkbook workbook = new XSSFWorkbook(fis);        

    // Getting the Sheet at index zero
    Sheet sheet = workbook.getSheetAt(0);

    // Create a DataFormatter to format and get each cell's value as String
    DataFormatter dataFormatter = new DataFormatter();

    for(int i = 1; i < sheet.getLastRowNum(); i++) {
        Row row = sheet.getRow(i);
        for(int j = 0; j < row.getLastCellNum(); j++) {
            Cell cell = row.getCell(j);

            switch(j) {
                case 0:
                    debiteurList.add(cell.toString());
                    break;
                case 3:
                    losnaamList.add(cell.toString());
                    break;
                case 5:
                    losadresList.add(cell.toString());
                    break;
                case 7:
                    lospostcodeList.add(cell.toString());
                    break;
                case 8:
                    losplaatsList.add(cell.toString());
                    break;
                case 9:
                    loslandList.add(cell.toString());
                    break;
                case 11:
                    totallinesList.add(cell.toString());
                    break;
                case 12:
                    opmerkingList.add(cell.toString());
                    break;
                case 14:
                    rijtypeList.add(cell.toString());
                    break;
                case 15:
                    beginlostijdList.add(cell.toString());
                    break;
                case 16:
                    eindlostijdList.add(cell.toString());
                    break;                      
            }
        }
    }

    System.out.println("successfully read xlsx");
    workbook.close();
}

这是错误：

好像您缺少依赖项。也许https://mvnrepository.com/artifact/org.apache.xmlbeans/xmlbeans/2.5.0
