我使用jxl读取.xls文件,下面是我解析xls文件的代码。它工作正常,但问题是当我插入日期字段时,它只读取年份的最后两位数。例如,如果我输入 12/13/2088 和 12/13/1988。它都将读作 12/13/88。有没有解决这个问题的方法。我可以对 Excel 单元格进行格式化或更改我当前的代码吗?
ArrayList listDet=new ArrayList();
HashMap mapDet=null;
HashMap primeDetails=new HashMap();
WorkbookSettings ws = null;
Workbook workbook = null;
Sheet s = null;
Cell rowData[] = null;
int rowCount = '0';
int columnCount1 = '0';
int columnCount = '0';
DateCell dc = null;
int totalSheet = 0;
try {
ws = new WorkbookSettings();
ws.setLocale(new Locale("en", "EN"));
ws.setCellValidationDisabled(true);
workbook = Workbook.getWorkbook(fileInputStream, ws);
totalSheet = workbook.getNumberOfSheets();
//Getting Default Sheet i.e. 0
s = workbook.getSheet(0);
//Total Total No Of Rows in Sheet, will return you no of rows that are occupied with some data
System.out.println("Total Rows inside Sheet:" + s.getRows());
rowCount = s.getRows();
//Total Total No Of Columns in Sheet
System.out.println("Total Column inside Sheet:" + s.getColumns());
columnCount = s.getColumns();
//Reading Individual Row Content
for (int i = 0; i <rowCount ; i++) {
//Get Individual Row
rowData = s.getRow(i);
mapDet=new HashMap();
mapDet.put("col1",rowData[0].getContents());
mapDet.put("col2",rowData[1].getContents());
mapDet.put("col3",rowData[2].getContents());
mapDet.put("col4",rowData[3].getContents());
mapDet.put("col5",rowData[4].getContents());
mapDet.put("col6",rowData[5].getContents());
mapDet.put("col7",rowData[6].getContents());
mapDet.put("col8",rowData[7].getContents());
mapDet.put("col9",rowData[8].getContents());
listDet.add(mapDet);
}
workbook.close();
} catch (IOException e) {
e.printStackTrace();
} catch (BiffException e) {
e.printStackTrace();
}
catch(Exception exp)
{
exp.printStackTrace();
}
最佳答案
根据 javadocs/2_6_10/docs/jxl/Cell方法: getContents() 是一个 “以字符串形式返回此单元格内容的快速而肮脏的函数。”
由于 getContents() 不允许完全控制格式,
您可以定义自己的函数来控制 CellType.DATE
的格式;
例如:
private String getContents(Cell cell) {
DateCell dCell=null;
if(cell.getType() == CellType.DATE)
{
dCell = (DateCell)cell;
// System.out.println("Value of Date Cell is: " + dCell.getDate());
// ==> Value of Date Cell is: Thu Apr 22 02:00:00 CEST 2088
SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd");
// System.out.println(sdf.format(dCell.getDate()));
// ==> 2088-04-22
return sdf.format(dCell.getDate());
}
// possibly manage other types of cell in here if needed for your goals

return cell.getContents();
}
然后你只需要根据调用你自己的私有(private)函数来更改代码:
mapDet.put("col1", getContents(rowData[0]));
mapDet.put("col2", getContents(rowData[1]));
mapDet.put("col3", getContents(rowData[2]));
mapDet.put("col4", getContents(rowData[3]));
mapDet.put("col5", getContents(rowData[4]));
mapDet.put("col6", getContents(rowData[5]));
mapDet.put("col7", getContents(rowData[6]));
mapDet.put("col8", getContents(rowData[7]));
mapDet.put("col9", getContents(rowData[8]));
代替
mapDet.put("col1",rowData[0].getContents());
...
mapDet.put("col9",rowData[8].getContents());
