如何用Apache POI在word文档中插入图像？

Question

public class ImageAttachmentInDocument {
    /**
     * @param args
     * @throws IOException
     * @throws InvalidFormatException 
     */
    public static void main(String[] args) throws IOException, InvalidFormatException {

        XWPFDocument doc = new XWPFDocument();   
        FileInputStream is = new FileInputStream("encabezado.jpg");
        doc.addPictureData(IOUtils.toByteArray(is), doc.PICTURE_TYPE_JPEG);


        XWPFParagraph title = doc.createParagraph();    
        XWPFRun run = title.createRun();
        run.setText("Fig.1 A Natural Scene");
        run.setBold(true);
        title.setAlignment(ParagraphAlignment.CENTER);

        FileOutputStream fos = new FileOutputStream("test4.docx");
        doc.write(fos);
        fos.flush();
        fos.close();        
    }
}

您似乎没有将图像附加到您希望显示的文本中！

从XWPF Simple Images示例中得到启发，我认为您希望代码是：

    XWPFDocument doc = new XWPFDocument();

    XWPFParagraph title = doc.createParagraph();    
    XWPFRun run = title.createRun();
    run.setText("Fig.1 A Natural Scene");
    run.setBold(true);
    title.setAlignment(ParagraphAlignment.CENTER);

    String imgFile = "encabezado.jpg";
    FileInputStream is = new FileInputStream(imgFile);
    run.addBreak();
    run.addPicture(is, XWPFDocument.PICTURE_TYPE_JPEG, imgFile, Units.toEMU(200), Units.toEMU(200)); // 200x200 pixels
    is.close();

    FileOutputStream fos = new FileOutputStream("test4.docx");
    doc.write(fos);
    fos.close();        

不同之处在于，不是显式地将图像附加到文档，而是将其添加到运行中。run add还将它添加到文档中，但重要的是，它还设置了一些内容，以引用希望它在其中显示的运行中的图片
