本文介绍使用 Spire.Office for Java 在 Word 文档中添加条码、二维码的方法。可在文档正文段落中添加，也可在页眉页脚中添加。除了使用本文中的方法外，也可以通过条码字体来创建，具体方法可参考这篇文章。

1、添加条码到 Word（添加到正文段落、页脚为例）

import com.spire.barcode.*;
import com.spire.doc.*;
import com.spire.doc.documents.HorizontalAlignment;
import com.spire.doc.documents.Paragraph;

import javax.imageio.ImageIO;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;

public class AddBarcode {
    public static void main(String[] args) throws IOException {
        //创建Document对象，加载Word文档
        Document doc = new Document();
        doc.loadFromFile("test.docx");

        //获取所有section
        for (int i = 0 ; i < doc.getSections().getCount();i++)
        {
            Section section = doc.getSections().get(i);

            //使用Spire.Barcode的BarcodeSettings和BarcodeGenerator类创建条码并保存为图片
            BarcodeSettings settings = new BarcodeSettings();
            settings.setType(BarCodeType.Code_128);
            settings.setData("123456789");
            settings.setData2D("123456789");
            settings.setShowText(false);
            settings.setBarHeight(4);
            settings.setX(0.3f);
            settings.hasBorder(true);
            settings.setBorderWidth(0.5f);
            settings.setBorderColor(new Color(135,206,250));
            settings.setBackColor(new Color(240,255,255));
            BarCodeGenerator barCodeGenerator = new BarCodeGenerator(settings);
            BufferedImage bufferedImage = barCodeGenerator.generateImage();
            ImageIO.write(bufferedImage, "png", new File("Barcode.png"));

            //添加条码到正文段落
            Paragraph paragraph = section.addParagraph();
            paragraph.setText("收货码：");
            paragraph.appendPicture("Barcode.png");
            paragraph.getFormat().setHorizontalAlignment(HorizontalAlignment.Right);

            //添加条码图片到Word页脚
            HeaderFooter footer = section.getHeadersFooters().getFooter();
            Paragraph footerpara = footer.addParagraph();
            footerpara.setText("扫码识真伪：");
            footerpara.appendPicture("Barcode.png");
            footerpara.getFormat().setHorizontalAlignment(HorizontalAlignment.Left);
        }

        //保存文档
        doc.saveToFile("BarCodeToWord.docx", FileFormat.Docx_2013);
        doc.dispose();
    }
}

2、添加二维码到 Word（添加到正文段落、页眉为例）

import com.spire.barcode.*;
import com.spire.doc.*;
import com.spire.doc.documents.HorizontalAlignment;
import com.spire.doc.documents.Paragraph;

import javax.imageio.ImageIO;
import java.awt.*;
import java.awt.image.RenderedImage;
import java.io.File;
import java.io.IOException;

public class AddQRCode {
    public static void main(String[] args) throws IOException {
        //创建Document对象，加载Word文档
        Document doc = new Document();
        doc.loadFromFile("test.docx");

        //获取所有section
        for (int i = 0 ; i < doc.getSections().getCount();i++)
        {
            Section section = doc.getSections().get(i);

            //使用Spire.Barcode的BarcodeSettings和BarcodeGenerator类创建二维码并保存为图片
            BarcodeSettings settings = new BarcodeSettings();
            settings.setType(BarCodeType.QR_Code);
            settings.setData("123456");
            settings.setData2D("123456");
            settings.setX(0.7f);
            settings.setLeftMargin(0);
            settings.setShowTextOnBottom(true);
            settings.setQRCodeECL(QRCodeECL.Q);
            settings.setQRCodeDataMode(QRCodeDataMode.Numeric);
            BarCodeGenerator generator = new BarCodeGenerator(settings);
            Image image = generator.generateImage();
            ImageIO.write((RenderedImage) image, "png", new File("QRCode.png"));

            //添加二维码到正文段落
            Paragraph paragraph = section.addParagraph();
            paragraph.appendPicture("QRCode.png");
            paragraph.getFormat().setHorizontalAlignment(HorizontalAlignment.Right);
            
            //添加二维码图片到Word页眉
            HeaderFooter header = section.getHeadersFooters().getHeader();
            Paragraph headerpara = header.addParagraph();
            headerpara.appendPicture("QRCode.png");
            headerpara.getFormat().setHorizontalAlignment(HorizontalAlignment.Center);
        }

        //保存文档
        doc.saveToFile("QRCodeToWord.docx", FileFormat.Docx_2013);
        doc.dispose();
    }
}
