java - 用图片替换了图片内容控件 - Word 在打开文件时报告灾难性故障

Question

我需要用图片替换图片内容控件。代码运行正常，但当 Word 尝试打开文件时，它报告灾难性失败:

代码基本上是ImageAdd的调整版本来自 docx4j 样本的类。有趣的是，转换为 PDF 的文档显示正常。

List<SdtElement> contentControls = findContentControls(wordMLPackage.getMainDocumentPart(InputStream));

for (SdtElement contentControl : contentControls) {
    for (Object ob : contentControl.getSdtContent().getContent()) {
        traverseEelements(ob, value);
    }
}

static List<SdtElement> findContentControls(ContentAccessor container) throws Docx4JException, JAXBException {
    List<SdtElement> sdtElements = new LinkedList<SdtElement>();
    for (Object o : container.getContent()) {
        Object unwrapped = XmlUtils.unwrap(o);
        if (unwrapped instanceof SdtElement) {
            sdtElements.add((SdtElement) unwrapped);
        }
        if (unwrapped instanceof ContentAccessor) {
            List<SdtElement> list = findContentControls((ContentAccessor) unwrapped);
            sdtElements.addAll(list);
        }
    }
    return sdtElements;
}

private void traverseEelements(Object object, String value) {
    if (object instanceof org.docx4j.wml.Text) {
        Text text = (org.docx4j.wml.Text) object;
        text.setValue(value);
    } else if (object instanceof ContentAccessor) {
        ContentAccessor contentAccessor = (ContentAccessor) object;
        for (Object ob : contentAccessor.getContent()) {
            traverseEelements(ob, value);
        }
    } else if (object instanceof JAXBElement) {
        Object v = ((JAXBElement<?>) object).getValue();
        if (v instanceof ContentAccessor) {
            ContentAccessor contentAccessor = (ContentAccessor) v;
            for (Object ob : contentAccessor.getContent()) {
                traverseEelements(ob, value);
            }
        } else if (v instanceof org.docx4j.wml.Text) {
            Text text = (org.docx4j.wml.Text) v;
            text.setValue(value);
        } else if (v instanceof org.docx4j.wml.Drawing) {
            Drawing drawing = (Drawing) v;
            try {
                File file = new File("C://Users//user//Pictures//test.png" );
                java.io.InputStream is = new java.io.FileInputStream(file );
                long length = file.length();  
                if (length > Integer.MAX_VALUE) {
                    System.out.println("File too large!!");
                }
                byte[] bytes = new byte[(int)length];
                int offset = 0;
                int numRead = 0;
                while (offset < bytes.length
                        && (numRead=is.read(bytes, offset, bytes.length-offset)) >= 0) {
                    offset += numRead;
                }
                // Ensure all the bytes have been read in
                if (offset < bytes.length) {
                    System.out.println("Could not completely read file "+file.getName());
                }
                is.close();
                String filenameHint = null;
                String altText = null;
                int id1 = 0;
                int id2 = 1;
                BinaryPartAbstractImage imagePart = BinaryPartAbstractImage.createImagePart(wordMLPackage, bytes );
                Inline inline = imagePart.createImageInline(filenameHint, altText, id1, id2, false);
                drawing.getAnchorOrInline().add(inline);
            } catch(Exception e) {
                logger.error(e);
            }
        } else {
            logger.error("unspupported element found: " + object.getClass());
        }
    } else {
        logger.error("unspupported element found: " + object.getClass());
    }
}

您有一个包含 wp:anchor 和 wp:inline: 的 w:drawing:

        </w:drawing>

这导致了失败。
