Java使用jbarcode生成条形码详解编程语言

java生成条形码需要jbarcode包，引用此包之后就可以很方便的生成条形码了。

如下代码实现：

import java.awt.image.BufferedImage;   
import java.io.FileOutputStream;   
import org.jbarcode.JBarcode;   
import org.jbarcode.encode.EAN8Encoder; 
import org.jbarcode.paint.EAN8TextPainter; 
import org.jbarcode.paint.WidthCodedPainter;   
import org.jbarcode.util.ImageUtil;   
/**

 * 支持EAN13, EAN8, UPCA, UPCE, Code 3 of 9, Codabar, Code 11, Code 93, Code 128, MSI/Plessey, Interleaved 2 of PostNet等 
 * 利用jbarcode生成各种条形码！测试成功！分享给大家！

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

            ImageUtil.encodeAndWrite(paramBufferedImage, paramString2, localFileOutputStream, 96, 96);
