如何在apache POI中添加HSSFCell中的图像？

Question

如何在poi中的不同HSSFCell对象中添加Image？

我写了一些添加图像的代码,但问题是,单元格是我添加的最后一个图像,该单元格只显示图像而不是其他单元格没有显示图像...

感谢您的帮助 ...

我的代码是

while(rs.next()){

    HSSFCell cell = getHSSFCell(sheet, rowNo, cellNo);

    cell.setCellValue(new HSSFRichTextString(rs.getString("TEST_STEP_DETAILS")) );
    cell.setCellStyle(style);

    String annotate = rs.getString("ANNOTATE");

    if(annotate != null){                       
        int index = getPicIndex(wb);
        HSSFPatriarch patriarch=sheet.createDrawingPatriarch();
        HSSFClientAnchor anchor = new HSSFClientAnchor(400,10,655,200,(short)cellNo,(rowNo+1),(short)cellNo,(rowNo+1));
        anchor.setAnchorType(1);
        patriarch.createPicture(anchor, index);                                         
    }
    cellNo++;
}

getPicIndex方法: -

public static int getPicIndex(HSSFWorkbook wb){
    int index = -1;
    try {
        byte[] picData = null;
        File pic = new File( "C:\\pdf\\logo.jpg" );
        long length = pic.length(  );
        picData = new byte[ ( int ) length ];
        FileInputStream picIn = new FileInputStream( pic );
        picIn.read( picData );
        index = wb.addPicture( picData, HSSFWorkbook.PICTURE_TYPE_JPEG );
    } catch (IOException e) {
        e.printStackTrace();
    }  catch (Exception e) {
        e.printStackTrace();
    } 
    return index;
}

我希望你自己找到解决方案.如果不是:
问题是你为每个图像创建一个新的partiarch. HSSFPatriarch patriarch = sheet.createDrawingPatriarch();
您应该只创建一个patriarch实例并对所有图像使用其createPicture方法.
