java生产条形码

 

一、通过JBarcode（此种方式可以隐藏掉条形码下面的字符串）

 

1.下载jar包  jbarcode-0.2.8.jar

 目前maven中央仓库并没有jbarcode的坐标

 如果是maven项目，需要我们自己上传jar包到自己的私服中并配置maven坐标

        <!--jbarcode-->

        <dependency>

            <groupId>org.jbarcode</groupId>

            <artifactId>JBarcode</artifactId>

            <version>0.2.8</version>

        </dependency>

 

2.工具代码：

package com.beiquan.tts.utils;

 

import org.jbarcode.JBarcode;

import org.jbarcode.encode.Code128Encoder;

import org.jbarcode.encode.EAN13Encoder;

import org.jbarcode.encode.InvalidAtributeException;

import org.jbarcode.paint.BaseLineTextPainter;

import org.jbarcode.paint.EAN13TextPainter;

import org.jbarcode.paint.WidthCodedPainter;

 

import javax.imageio.ImageIO;

import java.awt.image.BufferedImage;

import java.io.OutputStream;

public class JBarCodeUtils {

 

 

    /**

     * @param dimension

     * @param barheight

     *            商品条形码：高度

     * @return 图片(Base64编码)

     */

    public static void generateBarCode128(String strBarCode,String dimension,String barheight,OutputStream ous) {

 

 

        try {

            BufferedImage bi ;

            int len = strBarCode.length();

            JBarcode productBarcode = new JBarcode(Code128Encoder.getInstance(),

                    WidthCodedPainter.getInstance(),

                    EAN13TextPainter.getInstance());

 

            // 尺寸，面积，大小 密集程度

            productBarcode.setXDimension(Double.valueOf(dimension).doubleValue());

            // 高度 10.0 = 1cm 默认1.5cm

            productBarcode.setBarHeight(Double.valueOf(barheight).doubleValue());

            // 宽度

            productBarcode.setWideRatio(Double.valueOf(30).doubleValue());

//                  是否显示字体

            productBarcode.setShowText(false);

//                 显示字体样式

            productBarcode.setTextPainter(BaseLineTextPainter.getInstance());

 

            // 生成二维码

            bi = productBarcode.createBarcode(strBarCode);

 

            ImageIO.write(bi, "jpg", ous);

 

        } catch (Exception e) {

            e.printStackTrace();

            throw new RuntimeException(e);

        }

    }

 

 

 

 

 

    /**

     * 商品条形码

     * @param strBarCode

     *            商品条形码：13位

     * @param dimension

     *            商品条形码：尺寸

     * @param barheight

     *            商品条形码：高度

     * @return 图片(Base64编码)

     */

    public static void generateBarCode(String strBarCode,String dimension,String barheight,OutputStream ous) {

//      isNumeric 是否是数值

//      校验。。。。。

 

 

        try {

            BufferedImage bi ;

            int len = strBarCode.length();

            JBarcode productBarcode = new JBarcode(EAN13Encoder.getInstance(),

                    WidthCodedPainter.getInstance(),

                    EAN13TextPainter.getInstance());

 

            String barCode = strBarCode.substring(0, len - 1);

            String code = strBarCode.substring(len - 1, len);

 

            //校验13位

            String checkCode = productBarcode.calcCheckSum(barCode);

            if (!code.equals(checkCode)) {

            }

 

 

            // 尺寸，面积，大小

            productBarcode.setXDimension(Double.valueOf(dimension).doubleValue());

            // 高度 10.0 = 1cm 默认1.5cm

            productBarcode.setBarHeight(Double.valueOf(barheight).doubleValue());

            // 宽度

            productBarcode.setWideRatio(Double.valueOf(25).doubleValue());

 

            // 是否校验13位，默认false

            productBarcode.setShowCheckDigit(true);

 

            //显示字符串内容中是否显示检查码内容

//          productBarcode.setShowCheckDigit(true);

 

            // 生成二维码

            bi = productBarcode.createBarcode(barCode);

 

            ImageIO.write(bi, "jpg", ous);

 

        } catch (Exception e) {

            e.printStackTrace();

            throw new RuntimeException(e);

        }

    }

 

    /**

     * @param args

     * @throws InvalidAtributeException

     */

    public static void main(String[] args) throws InvalidAtributeException {

 

    }

}

 

 

 

二、通过barcode4j

1.配置maven 坐标

        <!--barcode4j-->

        <dependency>

            <groupId>net.sf.barcode4j</groupId>

            <artifactId>barcode4j-light</artifactId>

            <version>2.0</version>

        </dependency>

2.工具代码：

package com.beiquan.tts.utils;

 

import org.apache.commons.lang.StringUtils;

import org.krysalis.barcode4j.impl.code39.Code39Bean;

import org.krysalis.barcode4j.output.bitmap.BitmapCanvasProvider;

import org.krysalis.barcode4j.tools.UnitConv;

 

import java.awt.image.BufferedImage;

import java.io.*;

 

/**

public class CreateBarCodeUtils {

 

 

    /**

     * 生成文件

     *

     * @param msg

     * @param path

     * @return

     */

    public static File generateFile(String msg, String path) {

        File file = new File(path);

        try {

            generate(msg, new FileOutputStream(file));

        } catch (FileNotFoundException e) {

            throw new RuntimeException(e);

        }

        return file;

    }

 

    /**

     * 生成字节

     *

     * @param msg

     * @return

     */

    public static byte[] generate(String msg) {

        ByteArrayOutputStream ous = new ByteArrayOutputStream();

        generate(msg, ous);

        return ous.toByteArray();

    }

 

    /**

     * 生成到流

     *

     * @param msg

     * @param ous

     */

    public static void generate(String msg, OutputStream ous) {

        if (StringUtils.isEmpty(msg) || ous == null) {

            return;

        }

 

        Code39Bean bean = new Code39Bean();

 

        // 精细度

        final int dpi = 150;

        // module宽度

        final double moduleWidth = UnitConv.in2mm(1.0f / dpi);

 

        // 配置对象

        bean.setModuleWidth(moduleWidth);

        bean.setWideFactor(3);

        bean.doQuietZone(false);

 

        String format = "image/png";

        try {

 

            // 输出到流

            BitmapCanvasProvider canvas = new BitmapCanvasProvider(ous, format, dpi,

                    BufferedImage.TYPE_BYTE_BINARY, false, 0);

 

            // 生成条形码

            bean.generateBarcode(canvas, msg);

 

            // 结束绘制

            canvas.finish();

        } catch (IOException e) {

            throw new RuntimeException(e);

        }

    }

 

    public static void main(String[] args) {

        String msg = "123456789";

        String path = "barcode.png";

        generateFile(msg, path);

    }

}
