Apache POI XWPF將標題添加到標題

Question

我試圖在Word docx文檔的標題中添加一些形狀和標誌文件。添加圖片適用於我，但我沒有找到任何解決方案如何添加形狀。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 

在結束時，頭部應該像this

感謝

由於apache poiXWPF真的是處於測試狀態，直至現在，這樣的事情僅僅是可能的，如果一個人知道究竟是如何Word將存儲它的內容進入XML。然後可以解決apache poiXWPF的不足之處。您已經使用了這樣一種解決方法，可以在將圖片添加到頁眉或頁腳中運行時更正丟失的blipID。

要發現Word如何將其內容存儲到XML不是火箭科學。 A *.docx文件只是一個ZIP文件。如果使用Zip軟件解壓縮此文件，可以簡單查看XML文件。

據我所知直接在apache poi不支持在Word文檔中添加形狀（在本例中爲文本框）。爲此，需要使用底層對象（本例中爲CTGroup和CTShape）。

實施例：（代碼應該是自解釋）
