java实现条形码一维码的生成、打印功能源码

java实现条形码一维码JBarcode打印

因为公司最近得项目需要一个打印一维码的功能，百度了很多相关文章，自己重新整理了一下，生成一个工具类，可以直接实现生成一维码的功能，源代码如下：
开始前必须引入jbarcode包

org.jbarcode
jbarcode
0.2.8

工具类BarcodeUtils源代码如下：
public class BarcodeUtils {
// 设置条形码的高度
private static final int BARCODE_HEIGHT = 65;
// 设置条形码的分辨率
private static final int BARCODE_DPI = 300;

public static void createBarcode(String message, String fileName)
{
    try
    {
        JBarcode localJBarcode = new JBarcode(EAN13Encoder.getInstance(), WidthCodedPainter.getInstance(), EAN13TextPainter.getInstance());
        //生成. 欧洲商品条码(=European Article Number)
        //这里我们用作图书条码
        BufferedImage localBufferedImage = localJBarcode.createBarcode(message);
        saveToGIF(localBufferedImage, fileName);
        localJBarcode.setEncoder(Code39Encoder.getInstance());
        localJBarcode.setPainter(WideRatioCodedPainter.getInstance());
        localJBarcode.setTextPainter(BaseLineTextPainter.getInstance());
        localJBarcode.setBarHeight(BARCODE_HEIGHT);
        localJBarcode.setShowCheckDigit(false);


    }
    catch (Exception localException)
    {
        localException.printStackTrace();
    }
}

static void saveToJPEG(BufferedImage paramBufferedImage, String paramString)
{
    saveToFile(paramBufferedImage, paramString, "jpeg");
}

static void saveToPNG(BufferedImage paramBufferedImage, String paramString)
{
    saveToFile(paramBufferedImage, paramString, "png");
}

static void saveToGIF(BufferedImage paramBufferedImage, String paramString)
{
    saveToFile(paramBufferedImage, paramString, "gif");
}

static void saveToFile(BufferedImage paramBufferedImage, String paramString1, String paramString2)
{
    try
    {
        FileOutputStream localFileOutputStream = new FileOutputStream("D:/A/" + paramString1);
        ImageUtil.encodeAndWrite(paramBufferedImage, paramString2, localFileOutputStream, BARCODE_DPI, BARCODE_DPI);
        localFileOutputStream.close();
    }
    catch (Exception localException)
    {
        localException.printStackTrace();
    }
}

//测试
public static void main(String[] args){
    String message="788515004012";
    String fileName ="788515004012.jpg";
    BarcodeUtils.createBarcode(message, fileName);
}

}
