代码

package len;

import java.io.FileInputStream;

import java.util.ArrayList;

import java.util.Iterator;

import org.apache.poi.ss.usermodel.Cell;

import org.apache.poi.ss.usermodel.Row;

import org.apache.poi.ss.usermodel.Sheet;

import org.apache.poi.xssf.usermodel.XSSFWorkbook;

public class a {

    public static void main(String[] args) throws Exception{
        ArrayList data =new ArrayList();
        FileInputStream f =new FileInputStream("E:\\leadsuite.xlsx");
        XSSFWorkbook wb=new XSSFWorkbook(f);
        Sheet s=wb.getSheet("test steps");
        Iterator itr=s.iterator();
        while(itr.hasNext())
        {
            Row r=(Row) itr.next();
            Iterator cellitr=r.cellIterator();
            while(cellitr.hasNext())
            {
                Cell celldata=(Cell) cellitr.next();
                switch(celldata.getCellType())
                {
                case Cell.CELL_TYPE_STRING:
                    data.add(celldata.getStringCellValue());
                    break;
                case Cell.CELL_TYPE_NUMERIC:
                    data.add(celldata.getNumericCellValue());
                    break;
                case Cell.CELL_TYPE_BOOLEAN:
                    data.add(celldata.getBooleanCellValue());
                    break;
                }
            }

        }

    }

}

推荐答案

enum 是 STRING、NUMERIC 和 BOOLEAN，删除 CELL_TYPE_，它们是 CellType 枚举

The enums are STRING, NUMERIC and BOOLEAN, drop the CELL_TYPE_, and they are part of CellType enum

switch(celldata.getCellType()) {
    case CellType.STRING:
        data.add(celldata.getStringCellValue());
        break;
    case CellType.NUMERIC:
        data.add(celldata.getNumericCellValue());
        break;
    case CellType.BOOLEAN:
        data.add(celldata.getBooleanCellValue());
        break;
}
