java导入excel很完美的取值的方法
1.解决方法：
/** * 获取单元格数据内容为字符串类型的数据
* @param cell Excel单元格
* @return String 单元格数据内容
*/
private String getStringCellValue(Cell cell,String format) {
String strCell = "";
switch (cell.getCellType()) {
case XSSFCell.CELL_TYPE_STRING:
Pattern p = Pattern.compile("^[0-9]{4}[\\.\\-/](0?[1-9]|1[0-2])[\\.\\-/](0?[1-9]|[1-2][0-9]|3[0-1])$");
Matcher m = p.matcher(cell.getStringCellValue());
boolean b = m.matches();
if(b)
{
strCell=cell.getStringCellValue().replaceAll("[\\./]", "-");
}
else
{
strCell = cell.getStringCellValue();
}
break;
case XSSFCell.CELL_TYPE_NUMERIC:
if (DateUtil.isCellDateFormatted(cell)) {
// 如果是date类型则 ，获取该cell的date值
strCell = newSimpleDateFormat(format).format(DateUtil.getJavaDate(cell.getNumericCellValue()));
} else { // 纯数字
cell.setCellType(Cell.CELL_TYPE_STRING);
strCell = String.valueOf(cell.getStringCellValue());
}
break;
case XSSFCell.CELL_TYPE_BOOLEAN:
strCell = String.valueOf(cell.getBooleanCellValue());
break;
case XSSFCell.CELL_TYPE_BLANK:
strCell = "";
break;
default:
strCell = "";
break;
}
if (strCell.equals("") || strCell == null) {
return "";
}
if (cell == null) {
return "";
}
return strCell;
}
2.用法：
getStringCellValue(cell,"yyyy-MM-dd")；
getStringCellValue(cell,"yyyy-MM-dd HH:mm:ss");
getStringCellValue(cell,"HH:mm:ss");
