如何使用Apache POI在Word文档中插入图像?

问题描述：

我有此代码:

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();        
    }
}

(我正在Eclipse IDE中使用Apache POI 3.11和xmlbeans-2.3.0)

生成文档时，图像不显示

when I generate the document, the image is not displayed

我在做什么错了?

答

您似乎没有将图像附加到想要显示的文本上！

You don't seem to be attaching the image to the text where you want it shown!

从 XWPF简单图像示例，我想您想要的代码是:

Taking inspiration from the XWPF Simple Images Example, I think what you'd want your code to be is:

    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();

区别在于，您无需将图像显式附加到文档，而是将其添加到运行中.运行添加还将其添加到文档中，但重要的是还进行了一些设置，以引用您希望其显示在运行中的图片

The difference there is that rather than explicitly attaching the image to the document, you instead add it to a run. The run add also adds it to the document, but importantly also sets things up to reference the picture from the run you want it to show in
