How to insert a image in word document with Apache POI?
提问by Erika Hernández
I have this code:
我有这个代码：
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();
}
}
(I am using Apache POI 3.11 and xmlbeans-2.3.0 in eclipse IDE)
（我在 Eclipse IDE 中使用 Apache POI 3.11 和 xmlbeans-2.3.0）
when I generate the document, the image is not displayed

You don't seem to be attaching the image to the text where you want it shown!
您似乎没有将图像附加到您想要显示的文本中！
Taking inspiration from the XWPF Simple Images Example, I think what you'd want your code to be is:
从XWPF Simple Images Example 中汲取灵感，我认为您希望您的代码是：
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();
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
不同之处在于，不是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，但重要的是还设置了一些内容以引用您希望它显示的运行中的图片
