在日常生活中，条形码（一维码）和二维码主要是作为物品的标识来使用。条形码主要应用在商品标识、防伪、超市收银等场合；相比条形码（一维码）来说，二维码可以包含更多的信息，如网址、文字、图片等等。本文将使用Java代码来将条形码（一维码）和二维码添加到Word文档中。添加位置可是文档正文段落，也可是页眉页脚。

使用工具及Jar包导入

本教程需要用到 Free Spire.Office for Java （ 免费 ）控件。在运行代码前，需将控件中的Spire.Office.jar导入IDEA。可通过 E-iceblue中文官网 下载产品包，然后手动导入；也可通过 Maven 仓库安装导入（仅需在pom.xml中引入以下代码）

 <repositories>
        <repository>
            <id>com.e-iceblue</id>
            <url>
        </repository>
</repositories>
<dependencies>
    <dependency>
        <groupId>e-iceblue</groupId>
        <artifactId>spire.office.free</artifactId>
        <version>3.9.0</version>
    </dependency>

示例1 添加条形码（一维码）到Word文档 （ 以添加到正文段落、页脚为例 ）

        //创建Document对象，加载Word文档
        Document doc = new Document();
        doc.loadFromFile("C:\Users\Test1\Desktop\Sample.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.setBackColor(new Color(240,255,255));
            BarCodeGenerator barCodeGenerator = new BarCodeGenerator(settings);
            BufferedImage bufferedImage = barCodeGenerator.generateImage();
            ImageIO.write(bufferedImage, "png", new File("output/Barcode.png"));

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

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