1.把一个订单或者商品编号生成一维码

import com.sun.image.codec.jpeg.JPEGCodec;
import com.sun.image.codec.jpeg.JPEGEncodeParam;
import com.sun.image.codec.jpeg.JPEGImageEncoder;
import org.jbarcode.JBarcode;
import org.jbarcode.encode.Code128Encoder;
import org.jbarcode.encode.InvalidAtributeException;
import org.jbarcode.paint.BaseLineTextPainter;
import org.jbarcode.paint.WidthCodedPainter;

import java.awt.image.BufferedImage;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;

public class TestC {
    public static void main(String[] arge){
        JBarcode localJBarcode = new JBarcode(Code128Encoder.getInstance(), WidthCodedPainter.getInstance(), BaseLineTextPainter.getInstance());
        localJBarcode.setEncoder(Code128Encoder.getInstance());
        localJBarcode.setPainter(WidthCodedPainter.getInstance());
        localJBarcode.setTextPainter(BaseLineTextPainter.getInstance());
        localJBarcode.setShowCheckDigit(false);

        BufferedImage localBufferedImage = null;
        try {
            localBufferedImage = localJBarcode.createBarcode("dddd201606140001");
        } catch (InvalidAtributeException e) {
            e.printStackTrace();
        }
        OutputStream jos = null;
        try {
            jos = new FileOutputStream("E:\\imagesFile.jpg");
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
        JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(jos);
        JPEGEncodeParam jpegEP = JPEGCodec.getDefaultJPEGEncodeParam(localBufferedImage);
        jpegEP.setQuality((float) 1, true);
        try {
            encoder.encode(localBufferedImage, jpegEP);
            jos.flush();
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                jos.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}

结果：
