XSSFSheet.shiftRows 错误

Question

我想将 shiftRows() 用于 xlsx 文件，但我收到以下错误消息，即使我已正确导入 "org.apache.poi.ss.formula.FormulaShifter;"

Exception in thread "AWT-EventQueue-0" java.lang.NoSuchMethodError: org.apache.poi.ss.formula.FormulaShifter.createForRowShift(IIII)Lorg/apache/poi/ss/formula/FormulaShifter;

shiftRows() 确实移动了我的文件的行；但在那之后，程序不会运行其他命令。

代码如下：

 import java.util.*;
 import org.apache.poi.xssf.usermodel.*;

 XSSFWorkbook wb1;

 InputStream inp1 = new FileInputStream("/home/directory/Desktop/arx.xlsx");
 wb1 = new XSSFWorkbook(inp1);
 XSSFSheet sheet = wb1.getSheetAt(0);
 copyRow(wb1,sheet,5,2);


 FileOutputStream fileOut = new FileOutputStream("/home/directory/Desktop/arx.xlsx");
 wb1.write(fileOut);
 fileOut.close();

 private static void copyRow(XSSFWorkbook workbook, XSSFSheet worksheet, int sourceRowNum, int destinationRowNum) {
    // Get the source / new row
    XSSFRow newRow = worksheet.getRow(destinationRowNum);
    XSSFRow sourceRow = worksheet.getRow(sourceRowNum);

    // If the row exist in destination, push down all rows by 1 else create a new row
    if (newRow != null) {
        worksheet.shiftRows(destinationRowNum, worksheet.getLastRowNum(), 1);
    } else {
        newRow = worksheet.createRow(destinationRowNum);
    }

    // Loop through source columns to add to new row
    for (int i = 0; i < sourceRow.getLastCellNum(); i++) {
        // Grab a copy of the old/new cell
        XSSFCell oldCell = sourceRow.getCell(i);
        XSSFCell newCell = newRow.createCell(i);

        // If the old cell is null jump to next cell
        /*if (oldCell == null) {
            newCell = null;
            continue;
        }*/

        // Set the cell data value
     switch (oldCell.getCellType()) {
        case Cell.CELL_TYPE_BLANK:
            newCell.setCellValue(oldCell.getStringCellValue());
            break;
        case Cell.CELL_TYPE_BOOLEAN:
            newCell.setCellValue(oldCell.getBooleanCellValue());
            break;
        case Cell.CELL_TYPE_ERROR:
            newCell.setCellErrorValue(oldCell.getErrorCellValue());
            break;
        case Cell.CELL_TYPE_FORMULA:
            newCell.setCellFormula(oldCell.getCellFormula());
            break;
        case Cell.CELL_TYPE_NUMERIC:
            newCell.setCellValue(oldCell.getNumericCellValue());
            break;
        case Cell.CELL_TYPE_STRING:
            newCell.setCellValue(oldCell.getRichStringCellValue());
            break;
    }
        }
    }

详见this Apache POI FAQ Entry：

Can I mix POI jars from different versions?

No. This is not supported.

All POI jars in use must come from the same version. A combination such as poi-3.11.jar and poi-ooxml-3.9.jar is not supported, and will fail to work in unpredictable ways.

您需要确保您所有的 POI jar 都来自同一版本，然后一切正常
