POI将NUMERIC TO TEXT(读取excel)

1.在Java读取Excel会遇到报错 Cannot get a STRING value from a NUMERIC cell我就是遇到了这种坑,这里我来分享心得,希望能帮助到各位小伙伴们!

想看NUMERIC TO TEXT(生成excel)的请看这篇文章  :https://blog.csdn.net/jiaobuchong/article/details/77513253

 

在这里给大家说明下原因,是因为在导入Excel时你手动填的数字POI读取的时候默认会把他当做NUMBER来处理,而这时

你又用cell.getStringCellValue()所有会报错。我也是这个问题弄了好半天,终于想到一个通用的办法来解决,通过了解底层

源码来解决问题。请往下看.......

Java代码在读取的时候想要的是字符串:1242532523632,那怎么办?

 

public static String getCellStringValue(Cell cell) {
    if (cell == null) {
        return "";
    }
    CellType type = cell.getCellTypeEnum();
    String cellValue;
    switch (type) {
        case BLANK:
            cellValue = "";
            break;
        case _NONE:
            cellValue = "";
            break;
        case ERROR:
            cellValue = "";
            break;
        case BOOLEAN:
            cellValue = String.valueOf(cell.getBooleanCellValue());
            break;
        case NUMERIC:
            cellValue = NumberToTextConverter.toText(cell.getNumericCellValue());
            break;
        case STRING:
            cellValue = cell.getStringCellValue();
            break;
        case FORMULA:
            cellValue = cell.getCellFormula();
            break;
        default:
            cellValue = "";
            break;
    }
    return cellValue;
}
public static void readExcel() throws Exception {
    FileInputStream inputStream = new FileInputStream(new File("test.xlsx"));
    XSSFWorkbook workbook = new XSSFWorkbook(inputStream);
    Sheet sheet = workbook.getSheetAt(0);
    Cell cell = sheet.getRow(1).getCell(0);
    String cellValue = getCellStringValue(cell);
    System.out.println(cellValue);

    workbook.close();
    inputStream.close();
}

public static void main(String[] args) throws Exception {
    readExcel();
}

红颜色的可以不用看,在代码中你将cell传入方法中就可以了,直接就拿返回的字符串用。

到了这里就完了,希望此篇文章能帮到大家----------------------------
