使用Java读取Excel工作表的单列

问题描述

我有一张Excel工作表.我想编写一个将参数作为要读取的列号并返回包含该列中所有数据的数组的方法.

I have an excel sheet. I want to write a method which takes parameter as column number that to be read and return a array consist of all the data in that column.

然后将该列元素放置在xml工作表中.我该如何写一个方法来做到这一点?

And then to place that column element in xml sheet. How can I write a method to do that?

推荐答案

使用Apache POI.您可以在他们的使用情况页面中找到示例.

Use Apache POI. You can find example in their usage page.

Sheet sheet1 = wb.getSheetAt(0);
for (Row row : sheet1) {
    for (Cell cell : row) {
    // Here you might have to use the cell number to limit what you want.
        CellReference cellRef = new CellReference(row.getRowNum(), cell.getCellNum());
        System.out.print(cellRef.formatAsString());
        System.out.print(" - ");

        switch(cell.getCellType()) {
      case Cell.CELL_TYPE_STRING:
        System.out.println(cell.getRichStringCellValue().getString());
        break;
      case Cell.CELL_TYPE_NUMERIC:
        if(DateUtil.isCellDateFormatted(cell)) {
          System.out.println(cell.getDateCellValue());
        } else {
          System.out.println(cell.getNumericCellValue());
        }
        break;
      case Cell.CELL_TYPE_BOOLEAN:
        System.out.println(cell.getBooleanCellValue());
        break;
      case Cell.CELL_TYPE_FORMULA:
        System.out.println(cell.getCellFormula());
        break;
      default:
        System.out.println();
        }
    }
}
