Question

我正在尝试解析包含各种公式的excel文件。我编写的代码能够解析几乎所有类型的公式，但是，某些单元格包含像= C20这样的另一个单元格的引用。在这种类型的单元格中，我的代码是

 Unexpected arg eval type (org.apache.poi.ss.formula.eval.MissingArgEval)

我的代码能够处理以下类型

 =IF(D14=0;" - ";E14/D14), =IF('TreeData-Report'!AB92="H";"";SUM('TreeData-Report'!C92:'TreeData-Report'!E92)) .. etc.

但是当它作为C20，D14 ..等单一论点出现时，它就失败了。我会将代码发布到哪里失败

      while (cellIterator.hasNext() && cellIteratorTotal.hasNext()) {

            cellCount++;
            Cell currentCell = cellIterator.next();

            Cell currentCellTotal = cellIteratorTotal.next();


            String cellValue = excelManager.evalCell(currentCell);// from here i am sending the  value for validation 
            String cellValueTotal = excelManager.evalCell(currentCellTotal);

这是验证器类，我在其中查询单元格值的类型

public String evalCell(Cell cell) {
    String cellValue = "";
    if (cell.getCellTypeEnum() == CellType.STRING) {
        cellValue = cell.getStringCellValue();
    } else if (cell.getCellTypeEnum() == CellType.NUMERIC) {
        cellValue = formatDoubleNumberToString(cell.getNumericCellValue());
    } else if (cell.getCellTypeEnum() == CellType.FORMULA) {
        cellValue = evalFormulaCell(cell);
    }
    return cellValue.trim();
}

public String evalFormulaCell(Cell cell) {

    String cellValue = "";
    switch (formulaEvaluator.evaluateFormulaCellEnum(cell)) {//Here the code fails if cell contains C20,D14.. etc this type of values 
    case BOOLEAN:
        cellValue = String.valueOf(cell.getBooleanCellValue());
        break;
    case NUMERIC:
        cellValue = formatDoubleNumberToString(cell.getNumericCellValue());
        break;
    case STRING:
        cellValue = cell.getStringCellValue();
        break;
    case BLANK:
        cellValue = "";
        break;
    case ERROR:
        cellValue = "Error Occurred with Code :"+String.valueOf(cell.getErrorCellValue());
        break;
    case _NONE:
        cellValue = "";
        break;
    // CELL_TYPE_FORMULA will never occur
    case FORMULA:
        cellValue = "";
        break;
    }
    return cellValue;
}

请帮我处理这类错误，我很抱歉，我无法让我的帖子清晰透明。谢谢。我正在使用poi 3.16 jar。

如何在apache POI中处理Unexpected arg eval类型（org.apache.poi.ss.formula.eval.MissingArgEval）
