在Word文档的标题中添加图像时出现问题

Question

我正在Word文档的标题中添加图片。它显示了图像的框架，并显示“当前无法显示图像”。如果我在标题中添加文本，则显示该文本，如果在文档正文中添加图像，则它也显示该图像。获取图像并在标题上显示文本，也没有图像。

我的支票用完了，有人可以提出建议吗？

谢谢！

public static void createHeaderAndFotter(XWPFDocument document) throws IOException, BadElementException, InvalidFormatException {

    XWPFHeaderFooterPolicy headerFooterPolicy = document.getHeaderFooterPolicy();
    if (headerFooterPolicy == null) headerFooterPolicy = document.createHeaderFooterPolicy();

    File image = new ClassPathResource("/static/images/NIAB_Header.bmp").getFile();
    BufferedImage bimg1 = ImageIO.read(image);
    int width = bimg1.getWidth();
    int height = bimg1.getHeight();
    String imageName= image.getName();

    XWPFHeader header = headerFooterPolicy.createHeader(XWPFHeaderFooterPolicy.DEFAULT);

    XWPFParagraph paragraph = header.createParagraph();
//        XWPFParagraph paragraph = document.createParagraph();
    paragraph.setAlignment(ParagraphAlignment.CENTER);

    XWPFRun run = paragraph.createRun();

    run.addPicture(new FileInputStream(image), XWPFDocument.PICTURE_TYPE_PNG, imageName, Units.toEMU(width), Units.toEMU(height));
    run.setText("HEADER"); 
}

如果我删除此行上的注释并在前面添加注释，那么它将添加图像

        XWPFParagraph paragraph = document.createParagraph();

我认为这是否奏效很大程度上取决于所使用的apache poi版本。在以前的apache poi版本中，页眉/页脚中的图片存在多个问题。

以下是使用apache poi 4.0.1的最起码的工作代码。建议始终使用最新的稳定版本。

代码：

import java.io.FileInputStream;
import java.io.FileOutputStream;

import org.apache.poi.xwpf.usermodel.*;
import org.apache.poi.wp.usermodel.HeaderFooterType;
import org.apache.poi.util.Units;

public class CreateWordHeaderWithImage {

 public static void main(String[] args) throws Exception {

  XWPFDocument doc = new XWPFDocument();

  // the body content
  XWPFParagraph paragraph = doc.createParagraph();
  XWPFRun run = paragraph.createRun();  
  run.setText("The Body...");

  // create header
  XWPFHeader header = doc.createHeader(HeaderFooterType.DEFAULT);

  // header's first paragraph
  paragraph = header.getParagraphArray(0);
  if (paragraph == null) paragraph = header.createParagraph();
  paragraph.setAlignment(ParagraphAlignment.CENTER);

  run = paragraph.createRun();

  FileInputStream in = new FileInputStream("samplePict.jpeg");
  run.addPicture(in, Document.PICTURE_TYPE_JPEG, "samplePict.jpeg", Units.toEMU(100), Units.toEMU(50));
  in.close();  

  run.setText("HEADER"); 

  FileOutputStream out = new FileOutputStream("CreateWordHeaderWithImage.docx");
  doc.write(out);
  doc.close();
  out.close();

 }
}

结果：
