poi工具类

在开发过程中工具类可以简化我们的操作,提高代码重用.下面是我操作poi(一个Excel操作组件)的工具类.请大家指点

java 代码

import org.apache.poi.hssf.usermodel.HSSFCell;

public class PoiUtil {

    public static String getStringCell(HSSFCell cell) {
        String str = null;
        if (cell != null) {
            switch (cell.getCellType()) {
                case HSSFCell.CELL_TYPE_NUMERIC:
                case HSSFCell.CELL_TYPE_FORMULA:
                    str = new Long((long) cell.getNumericCellValue()).toString();
                    break;
                case HSSFCell.CELL_TYPE_STRING:
                    str = cell.getStringCellValue().trim();
                    break;
                default:
                    break;
            }
        }

        return str;
    }

    public static double getNumericCell(HSSFCell cell) {
        double doub = 0;
        if (cell != null) {
            switch (cell.getCellType()) {
                case HSSFCell.CELL_TYPE_NUMERIC:
                case HSSFCell.CELL_TYPE_FORMULA:
                    doub = cell.getNumericCellValue();
                    break;
                case HSSFCell.CELL_TYPE_STRING:
                    doub = Double.parseDouble(cell.getStringCellValue().trim());
                    break;
                default:
                    break;
            }
        }

        return doub;
    }

    public static long getLongCell(HSSFCell cell) {

        return (long) getNumericCell(cell);
    }

    public static int getIntCell(HSSFCell cell) {

        return (int) getNumericCell(cell);
    }

    public static String getDateCell(HSSFCell cell) {
        String date = null;
        if (cell != null) {
            switch (cell.getCellType()) {
                case HSSFCell.CELL_TYPE_STRING:
                    date = cell.getStringCellValue();
                    break;
                case HSSFCell.CELL_TYPE_BLANK:
                case HSSFCell.CELL_TYPE_BOOLEAN:
                case HSSFCell.CELL_TYPE_ERROR:
                    break;
                default:
                    date = DateUtil.date2str(cell.getDateCellValue(), "yyyy-MM-dd");
            }
        }

        return date;
    }
}

 

不知大家是否还有更好的封装.拿出来交流下~O~
