Apache POI XWPF向標頭添加形狀

Question

我試圖在我的Word docx文檔的標題中添加一些形狀和徽標文件。 添加圖片對我有用，但是我找不到如何添加形狀的任何解決方案。 誰能幫我？

String imgFile="logo.png";

XWPFDocument document = new XWPFDocument(new FileInputStream("myfile.docx"));

CTSectPr sectPr = document.getDocument().getBody().addNewSectPr();

XWPFHeaderFooterPolicy headerFooterPolicy = new XWPFHeaderFooterPolicy(document, sectPr);               
XWPFHeader header = headerFooterPolicy.createHeader(XWPFHeaderFooterPolicy.DEFAULT);

XWPFParagraph paragraph = header.getParagraphArray(0);
paragraph.setAlignment(ParagraphAlignment.CENTER);

XWPFRun run = paragraph.createRun();
XWPFPicture picture = run.addPicture(new FileInputStream(imgFile), XWPFDocument.PICTURE_TYPE_PNG, imgFile, Units.toEMU(195), Units.toEMU(22));

String blipID = "";
for(XWPFPictureData picturedata : header.getAllPackagePictures()) {
  blipID = header.getRelationId(picturedata);
}
picture.getCTPicture().getBlipFill().getBlip().setEmbed(blipID); //now they have a blipID too

最后，標題應如下所示

謝謝

由於apache poi XWPF還處於beta狀態，因此只有在確切知道Word如何將其內容存儲到XML ，這種情況才有可能。 然后，可以解決apache poi XWPF的不足之XWPF 。 您已經使用了一種變通方法，當將圖片添加到頁眉或頁腳中運行時，它會糾正錯過的blipID 。

發現Word如何將其內容存儲到XML中不是火箭科學。 *.docx文件只是一個ZIP文件。 如果使用Zip軟件解壓縮該文件，則只需查看一下XML文件即可。

據我所知， apache poi直接支持在Word文檔中添加形狀（在這種情況下為文本框）。 為此，需要使用底層基礎對象（在本例中為CTGroup和CTShape ）。
