在word文档中插入图片

Question

这是我第一次在 Apache POI 上工作，我要问的问题已经在这个网站上提出过，但没有给他们明确的答案，所以我别无选择，只能接受你的帮助。

我正在尝试编写一个 java 程序，该程序从一个文件夹中获取图像并将该图像插入到 word 文档中。我正在为这个程序使用 Apache POI。我在这里发布我的代码。

import java.io.*;
import java.util.*;
import org.apache.poi.util.IOUtils;
import org.apache.poi.xwpf.usermodel.*;

public class ImagesDoc 
{
    public static void main(String[] args) throws IOException 
    {
        XWPFDocument docx = new XWPFDocument();
        XWPFParagraph par = docx.createParagraph();
        XWPFRun run = par.createRun();
        run.setText("Hello, World. This is my first java generated docx-file. Have fun.");
        run.setFontSize(13);
        InputStream pic = new FileInputStream("C:\\Users\\amitabh\\Pictures\\pics\\pool.jpg");
        byte [] picbytes = IOUtils.toByteArray(pic);
        docx.addPicture(picbytes, Document.PICTURE_TYPE_JPEG);

        FileOutputStream out = new FileOutputStream("C:\\Users\\amitabh\\Pictures\\pics\\simple1.docx"); 
        docx.write(out); 
        out.close(); 
        pic.close();
    }
}

我可以创建 word 文档文件，也可以插入文本，但 docx.addPicture(picbytes, Document.PICTURE_TYPE_JPEG); 行给我的错误是“将演员表添加到 docx”。我已经为这个程序添加了所有可能的 jar。对于这个错误，我在网上搜索了整个网络，发现很多人都有类似的问题。 XWPFDocument 参考的“addPicture”不起作用。请帮我解决这个问题。

Answer 1

首先，我想指出apache poi提供的示例-Link，即正确的做法是

doc.createParagraph().createRun().addPicture(new FileInputStream(imgFile), format, imgFile, Units.toEMU(200), Units.toEMU(200));

但是，执行上述语句后，仍然存在一个导致 .docx 文件无法读取的错误。它可能很快就会得到解决，在这种情况下，上述语句将完成工作。与此同时，有一个变通办法。

首先，生成没有任何图片的docx文件。然后将这个类 CustomXWPFDocument 添加到你的包中。

import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.xmlbeans.XmlException;
import org.apache.xmlbeans.XmlToken;
import org.openxmlformats.schemas.drawingml.x2006.main.CTNonVisualDrawingProps;
import org.openxmlformats.schemas.drawingml.x2006.main.CTPositiveSize2D;
import org.openxmlformats.schemas.drawingml.x2006.wordprocessingDrawing.CTInline;

import java.io.IOException;
import java.io.InputStream;

public class CustomXWPFDocument extends XWPFDocument
{
    public CustomXWPFDocument(InputStream in) throws IOException
    {
        super(in);
    }

    public void createPicture(String blipId,int id, int width, int height)
    {
        final int EMU = 9525;
        width *= EMU;
        height *= EMU;
        //String blipId = getAllPictures().get(id).getPackageRelationship().getId();


        CTInline inline = createParagraph().createRun().getCTR().addNewDrawing().addNewInline();

        String picXml = "" +
                "<a:graphic xmlns:a=\"http://schemas.openxmlformats.org/drawingml/2006/main\">" +
                "   <a:graphicData uri=\"http://schemas.openxmlformats.org/drawingml/2006/picture\">" +
                "      <pic:pic xmlns:pic=\"http://schemas.openxmlformats.org/drawingml/2006/picture\">" +
                "         <pic:nvPicPr>" +
                "            <pic:cNvPr id=\"" + id + "\" name=\"Generated\"/>" +
                "            <pic:cNvPicPr/>" +
                "         </pic:nvPicPr>" +
                "         <pic:blipFill>" +
                "            <a:blip r:embed=\"" + blipId + "\" xmlns:r=\"http://schemas.openxmlformats.org/officeDocument/2006/relationships\"/>" +
                "            <a:stretch>" +
                "               <a:fillRect/>" +
                "            </a:stretch>" +
                "         </pic:blipFill>" +
                "         <pic:spPr>" +
                "            <a:xfrm>" +
                "               <a:off x=\"0\" y=\"0\"/>" +
                "               <a:ext cx=\"" + width + "\" cy=\"" + height + "\"/>" +
                "            </a:xfrm>" +
                "            <a:prstGeom prst=\"rect\">" +
                "               <a:avLst/>" +
                "            </a:prstGeom>" +
                "         </pic:spPr>" +
                "      </pic:pic>" +
                "   </a:graphicData>" +
                "</a:graphic>";

        //CTGraphicalObjectData graphicData = inline.addNewGraphic().addNewGraphicData();
        XmlToken xmlToken = null;
        try
        {
            xmlToken = XmlToken.Factory.parse(picXml);
        }
        catch(XmlException xe)
        {
            xe.printStackTrace();
        }
        inline.set(xmlToken);
        //graphicData.set(xmlToken);

        inline.setDistT(0);
        inline.setDistB(0);
        inline.setDistL(0);
        inline.setDistR(0);

        CTPositiveSize2D extent = inline.addNewExtent();
        extent.setCx(width);
        extent.setCy(height);

        CTNonVisualDrawingProps docPr = inline.addNewDocPr();
        docPr.setId(id);
        docPr.setName("Picture " + id);
        docPr.setDescr("Generated");
    }
}

然后，通过添加您的图片来创建更新的文档：-

CustomXWPFDocument document = new CustomXWPFDocument(new FileInputStream(new File("C:\\Users\\Avarice\\Desktop\\doc1.docx")));
        FileOutputStream fos = new FileOutputStream(new File("C:\\Users\\Avarice\\Desktop\\doc2.docx"));
        String id = document.addPictureData(new FileInputStream(new File("C:\\Users\\Avarice\\Desktop\\thumbnail.jpg")), Document.PICTURE_TYPE_JPEG);
        document.createPicture(id,document.getNextPicNameNumber(Document.PICTURE_TYPE_JPEG), 64, 64);
        document.write(fos);
        fos.flush();
        fos.close();

您的构建路径中还应该有以下 jar：-

poi-ooxml 模式

xmlbeans

dom4j

    I have used poi 3.10 to generate word doc and to insert a picture. you need 2 classes.. here is the example
