在docx4j中创建新标头

WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.createPackage();

HeaderPart headerPart = new HeaderPart();
wordMLPackage.getMainDocumentPart().addTargetPart(headerPart);

// 设置标头内容
Header header = factory.createHeader();
headerPart.setJaxbElement(header);

// 添加文本到标头
P paragraph = factory.createP();
Text text = factory.createText();
text.setValue("这是一个新的标头");
paragraph.getContent().add(text);
header.getContent().add(paragraph);

// 添加图片到标头
File imageFile = new File("image.jpg");
byte[] imageBytes = FileUtils.readFileToByteArray(imageFile);
BinaryPartAbstractImage imagePart = BinaryPartAbstractImage.createImagePart(wordMLPackage, imageBytes);
Inline inline = imagePart.createImageInline("image", "image", 0, 1, false);
header.getContent().add(inline);

// 获取文档的节（section）
List<SectionWrapper> sections = wordMLPackage.getDocumentModel().getSections();

// 将标头应用到每个节
for (SectionWrapper section : sections) {
    HeaderFooterPolicy headerFooterPolicy = section.getHeaderFooterPolicy();
    if (headerFooterPolicy == null) {
        headerFooterPolicy = new HeaderFooterPolicy(wordMLPackage);
        section.setHeaderFooterPolicy(headerFooterPolicy);
    }
    headerFooterPolicy.getDefaultHeader().setHeaderReference(headerPart);
}
