使用SXSSF（APACHE POI）和添加注释不能生成正确的excel文件

Question

实际代码：

    public static void main(String[] args) throws Exception {
   // Workbook wb = new XSSFWorkbook();
    SXSSFWorkbook wb = new SXSSFWorkbook(100);
    Sheet sh = wb.createSheet();       
    for(int rownum = 0; rownum < 1000; rownum++){
        Row row = sh.createRow(rownum);
        for(int cellnum = 0; cellnum < 10; cellnum++){
            Cell cell = row.createCell(cellnum);
            String address = new CellReference(cell).formatAsString();
            cell.setCellValue(address);
            setCellComment(cell,address);                
        }
    }

    FileOutputStream out = new FileOutputStream("comments.xlsx");
    wb.write(out);
    out.close();
}

 protected static void setCellComment(Cell cell, String message) {
        Drawing drawing = cell.getSheet().createDrawingPatriarch();
        CreationHelper factory = cell.getSheet().getWorkbook()
                .getCreationHelper();
        // When the comment box is visible, have it show in a 1x3 space
        ClientAnchor anchor = factory.createClientAnchor();
        anchor.setCol1(cell.getColumnIndex());
        anchor.setCol2(cell.getColumnIndex() + 1);
        anchor.setRow1(cell.getRowIndex());
        anchor.setRow2(cell.getRowIndex() + 1);
        anchor.setDx1(100);
        anchor.setDx2(100);
        anchor.setDy1(100);
        anchor.setDy2(100);

        // Create the comment and set the text+author
        Comment comment = drawing.createCellComment(anchor);
        RichTextString str = factory.createRichTextString(message);
        comment.setString(str);
        comment.setAuthor("Apache POI");
        // Assign the comment to the cell
        cell.setCellComment(comment);
    }

我也遇到了同样的问题，并通过在comment上设置行和列属性解决了这个问题。

按照以下方式修改示例中的setCellComment()方法应该可以解决问题。

protected static void setCellComment(Cell cell, String message) {

    ...

    // Create the comment and set the text+author
    Comment comment = drawing.createCellComment(anchor);
    RichTextString str = factory.createRichTextString(message);
    comment.setString(str);
    comment.setAuthor("Apache POI");

    // Set the row and column here
    comment.setRow(cell.getRowIndex());
    comment.setColumn(cell.getColumnIndex());

    // Assign the comment to the cell
    cell.setCellComment(comment);
} 

通过查看XSSFCell类中的setCellComment()方法的源代码，我发现了这个解决方案。sxssfcell中的相应方法不设置行或列。
