关于Cell中的各种值的类型判断

switch (cell.getCellType()){
    case Cell.CELL_TYPE_NUMERIC: //数字
 cellValue = stringDateProcess(cell);
 break;
 case Cell.CELL_TYPE_STRING: //字符串
 cellValue = String.valueOf(cell.getStringCellValue());
 break;
 case Cell.CELL_TYPE_BOOLEAN: //Boolean
 cellValue = String.valueOf(cell.getBooleanCellValue());
 break;
 case Cell.CELL_TYPE_FORMULA: //公式
 cellValue = String.valueOf(cell.getCellFormula());
 break;
 case Cell.CELL_TYPE_BLANK: //空值
 cellValue = "";
 break;
 case Cell.CELL_TYPE_ERROR: //故障
 cellValue = "非法字符";
 break;
 default:
 cellValue = "未知类型";
 break;
}
