利用barcode4j生成条形码，下载barcode4j，将build下的barcode4j.jar加到你的classpath中即可


	package k.barcode;

	import java.awt.image.BufferedImage;
	import java.io.File;
	import java.io.FileOutputStream;
	import java.io.OutputStream;

	import org.krysalis.barcode4j.impl.code39.Code39Bean;
	import org.krysalis.barcode4j.output.bitmap.BitmapCanvasProvider;
	import org.krysalis.barcode4j.tools.UnitConv;

	public class Barcode {

	public static void main(String[] args) {
	 try {
	 //Create the barcode bean
	 Code39Bean bean = new Code39Bean();
	
	 final int dpi = 150;
	
	 //Configure the barcode generator
	 bean.setModuleWidth(UnitConv.in2mm(1.0f / dpi)); //makes the narrow bar
	 //width exactly one pixel
	 bean.setWideFactor(3);
	 bean.doQuietZone(false);
	
	 //Open output file
	 File outputFile = new File("d:\\out.png");
	 OutputStream out = new FileOutputStream(outputFile);
	 try {
	 //Set up the canvas provider for monochrome JPEG output
	 BitmapCanvasProvider canvas = new BitmapCanvasProvider(
	 out, "image/png", dpi, BufferedImage.TYPE_BYTE_BINARY, false, 0);
	
	 //Generate the barcode
	 bean.generateBarcode(canvas, "A123456");
	
	 //Signal end of generation
	 canvas.finish();
	 } finally {
	 out.close();
	 }
	 } catch (Exception e) {
	 e.printStackTrace();
	 }
	}

	}
