Question

我的代码确实存在一些问题。真的很感激，如果有人帮助我。下面是我的代码和它的2个截图，以及代码执行时的样子。

try {
response.setContentType("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
response.setHeader("Content-Disposition", "attachment; filename="+ ReportID + ".xlsx");

String excelFileName = "C:\\Test.xlsx";
XSSFWorkbook w = new XSSFWorkbook();
System.out.println("w: " + w);
XSSFSheet s = w.createSheet(ReportID);
System.out.println("s: " + s);

// Report Title
s.createRow(0).createCell(0).setCellValue(Title);
System.out.println("Title: " + Title);

// Populate the worksheet
int _col_cnt = HeadersLabel.length;
XSSFRow row = s.createRow(_col_cnt);
System.out.println("HeadersLabel: " + _col_cnt);

for (int c = 0; c < _col_cnt; c++) {
// Construct the header row
String _h = HeadersLabel[c];
System.out.println("_h: " + _h);

if (_h != null) {
    XSSFCell hd = row.createCell(c);
    hd.setCellValue(_h);                    
}       

 int r = 3;     
for (Iterator iter = Cells.iterator();iter.hasNext();) {
                Object[]  _o = (Object[]) iter.next();
                currentRow = s.createRow(r);
            for(int colNum = 0; colNum < _col_cnt; colNum++){
                XSSFCell currentCell =currentRow.createCell(colNum);       

                if (CellDataType[c].equals("STRING")
                        || CellDataType[c].equals("VARCHAR")) {
                    String _l = (String) _o[colNum];
                    if (_l != null) {
                        currentCell.setCellValue(_l);
                        System.out.println("Data: " + _l);
                    }       
                }

    else if (CellDataType[c].equals("DOUBLE")) {
                    Double _D = (Double) _o[c];
                    if (_D != null) {
                        //XSSFCell cell = rowData.createCell(c);
                        cell.setCellValue(_D);
                    }

                } else if (CellDataType[c].equals("INTEGER")) {
                    Integer _I = (Integer) _o[c];
                    if (_I != null) {
                        //XSSFCell cell = rowData.createCell(c);
                        cell.setCellValue(_I);

                    }
                } else if (CellDataType[c].equals("DATE")) {
                    Date _aDate = (Date) _o[c];
                    if (_aDate != null) {
                        //XSSFCell cell = rowData.createCell(c);
                        cell.setCellValue(_aDate);
                    }
                } else if (CellDataType[c].equals("TIMESTAMP")) {
                    Timestamp _aTimestamp = (Timestamp) _o[c];
                    Date _aDate = Timestamp2Date(_aTimestamp);
                    if (_aDate != null) {
                        //XSSFCell cell = rowData.createCell(c);
                        cell.setCellValue(_aDate);

                    }
                }
        r++;
    }

}

FileOutputStream fos = new FileOutputStream(excelFileName);
//w.write(response.getOutputStream());
w.write(fos);
fos.close();

} catch (Exception e) {
e.printStackTrace();
} finally {
if (out != null) {
    try {
        out.close();
    } catch (IOException e1) {
        e1.printStackTrace();
    }
}
}

context.responseComplete();

}

XLSX excel无法捕获一些数据。当假设出现数据时，前两列是空的。只有第三列有数据。

现在的样子：https://www.dropbox.com/s/2vfxsootyln6qq5/Capture3.JPG它应该是什么样的：https://www.dropbox.com/s/d0yctgk4pywh140/Capture2.JPG
