我试图在我的Word docx文档的标题中添加一些形状和徽标文件。添加图片对我有用，但是我找不到如何添加形状的任何解决方案。谁能帮我？

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，标题应如下所示

谢谢

回答：

由于apache poi

XWPF到目前为止，确实处于beta状态，因此只有在确切知道Word将其内容存储到中的情况下，此类事情才有可能XML。这样就可以解决的不足apache

poiXWPF。您已经使用了一种变通方法，blipID当将图片添加到页眉或页脚中运行时，它可以纠正错过的情况。

发现如何Word将其内容存储到XML容器中不是火箭科学。一个*.docx文件就是一个ZIP文件。如果使用Zip软件将该文件解压缩，则只需查看一下XML文件即可。

据我所知，不apache

poi直接支持在Word文档中添加形状（在这种情况下为文本框）。对于这种使用低级别底层对象（在这种情况下CTGroup和CTShape）是必要的。
