Java實現新增條碼或二維條碼到Word檔案

2022-05-31 18:00:11

本文介紹如何在Word檔案中新增條碼、二維條碼。可在檔案正文段落中新增,也可在頁首頁尾中新增。下面將通過Java程式碼範例介紹如何實現。

使用工具:Free Spire.Office for Java(免費版)

關於Jar匯入的方法:

方法1通過E-iceblue官網下載jar包,下載後,解壓,將lib資料夾下的Spire.Office.jar匯入Java程式;

方法2:通過建立Maven程式,並設定在pom.xml檔案中設定Maven倉庫路徑並指定Free Spire.Office for Java的Maven依賴,設定完成後,在IDEA中,點選“Import Changes”匯入JAR包。

<repositories>
        <repository>
            <id>com.e-iceblue</id>
            <url>http://repo.e-iceblue.cn/repository/maven-public/</url>
        </repository>
</repositories>

<dependencies>
    <dependency>
       <groupId>e-iceblue</groupId>
  <artifactId>spire.office.free</artifactId>
  <version>3.1.1</version>
</dependency>
</dependencies>

jar匯入結果如下圖所示:

Java程式碼範例

1. 新增條碼到Word(這裡以新增到Word正文、頁尾為例)

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 {
        //建立Document物件,載入Word檔案
        Document doc = new Document();
        doc.loadFromFile("test.docx");

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

            //使用Spire.Barcode的BarcodeSettings和BarcodeGenerator類建立條碼並儲存為圖片
            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"));

            //新增條碼到正文段落
            Paragraph paragraph = section.addParagraph();
            paragraph.setText("收貨碼:");
            paragraph.appendPicture("Barcode.png");
            paragraph.getFormat().setHorizontalAlignment(HorizontalAlignment.Right);

            //新增條碼圖片到Word頁尾
            HeaderFooter footer = section.getHeadersFooters().getFooter();
            Paragraph footerpara = footer.addParagraph();
            footerpara.setText("掃碼識真偽:");
            footerpara.appendPicture("Barcode.png");
            footerpara.getFormat().setHorizontalAlignment(HorizontalAlignment.Left);
        }

        //儲存檔案
        doc.saveToFile("BarCodeToWord.docx", FileFormat.Docx_2013);
        doc.dispose();
    }
}

2. 新增二維條碼到Word(這裡以新增到正文、頁首為例)

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 {
        //建立Document物件,載入Word檔案
        Document doc = new Document();
        doc.loadFromFile("test.docx");

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

            //使用Spire.Barcode的BarcodeSettings和BarcodeGenerator類建立二維條碼並儲存為圖片
            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"));

            //新增二維條碼到正文段落
            Paragraph paragraph = section.addParagraph();
            paragraph.appendPicture("QRCode.png");
            paragraph.getFormat().setHorizontalAlignment(HorizontalAlignment.Right);
            
            //新增二維條碼圖片到Word頁首
            HeaderFooter header = section.getHeadersFooters().getHeader();
            Paragraph headerpara = header.addParagraph();
            headerpara.appendPicture("QRCode.png");
            headerpara.getFormat().setHorizontalAlignment(HorizontalAlignment.Center);
        }

        //儲存檔案
        doc.saveToFile("QRCodeToWord.docx", FileFormat.Docx_2013);
        doc.dispose();
    }
}
