以上是excl格式。
功能:读取数据,插入数据库(包括空数据)。
问题:读取不了空数据。
代码:private static List<List<Object>> read2007Excel(File file)
throws IOException {
List<List<Object>> list = new LinkedList<List<Object>>();
// 构造 XSSFWorkbook 对象,strPath 传入文件路径
XSSFWorkbook xwb = new XSSFWorkbook(new FileInputStream(file));
// 读取第一张表格内容
XSSFSheet sheet = xwb.getSheetAt(0);
Object value = null;
XSSFRow row = null;
XSSFCell cell = null;
for (int i = (sheet.getFirstRowNum()+1); i <=(sheet.getPhysicalNumberOfRows()-1); i++) {
row = sheet.getRow(i);
if (row == null) {
continue;
}
List<Object> linked = new LinkedList<Object>();
for (int j = row.getFirstCellNum(); j <= row.getLastCellNum(); j++) {
cell = row.getCell(j);
if (cell == null) {
continue;
}
DecimalFormat df = new DecimalFormat("0");// 格式化 number String字符
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");// 格式化日期字符串
DecimalFormat nf = new DecimalFormat("0");// 格式化数字
switch (cell.getCellType()) {
case XSSFCell.CELL_TYPE_STRING:
System.out.println(i + "行" + j + " 列 is String type");
value = cell.getStringCellValue();
break;
case XSSFCell.CELL_TYPE_NUMERIC:
System.out.println(i + "行" + j
+ " 列 is Number type ; DateFormt:"
+ cell.getCellStyle().getDataFormatString());
if ("@".equals(cell.getCellStyle().getDataFormatString())) {
value = df.format(cell.getNumericCellValue());
} else if ("General".equals(cell.getCellStyle()
.getDataFormatString())) {
value = nf.format(cell.getNumericCellValue());
} else {
value = sdf.format(HSSFDateUtil.getJavaDate(cell
.getNumericCellValue()));
}
break;
case XSSFCell.CELL_TYPE_BOOLEAN:
System.out.println(i + "行" + j + " 列 is Boolean type");
value = cell.getBooleanCellValue();
break;
case XSSFCell.CELL_TYPE_BLANK:
System.out.println(i + "行" + j + " 列 is Blank type");
value = "";
break;
default:
System.out.println(i + "行" + j + " 列 is default type");
value = cell.toString();
}
linked.add(value);
}
list.add(linked);
}
return list;
}测试结果:
1行0 列 is String type
1行2 列 is String type
1行4 列 is String type
1行5 列 is String type
1行11 列 is String type

希望有人帮助解答,感谢。
