主要实现生成二维码程序，共生成两种一种使用QRcode生成，别一种用barcode4j生成，运行环境为JDK1.5
相关JAR包及程序，我会在最后附上，共大家下载，找这些组件还是挺费事的，呵
IBarcode定义条码接口
1 package com.xqrj.barcode;
2
3 import com.xqrj.barcode.exception.BarcodeException;
4
5 public interface IBarcode {
6 /**
7 * 设置高度
8 * @param width 高度
9 * @return void
10 */
11 public void setWidth(float width);
12 /**
13 * 设置宽度
14 * @param weight 宽度
15 * @return void
16 */
17 public void setHeight(float height);
18 /**
19 * 设置类型
20 * @param imgType 图片类型(JPG等)
21 * @return
22 */
23 public void setImgType(String imgType);
24 /**
25 * 设置类型
26 * @param barcodeType 条码类型
27 * @return
28 */
29 public void setBarcodeType(String barcodeType);
30 /**
31 * 构建条码数据
32 * @param buff 条码源数据
33 * @return byte[] 条码结果数据
34 */
35 public byte[] buildData(byte[] buff) throws BarcodeException;
36 /**
37 * 构建条码数据
38 * @param buff 条码源数据
39 * @param fileName 文件名称
40 * @return byte[] 条码结果数据
41 */
42 public void buildData(byte[] buff,String fileName) throws BarcodeException;
43 /**
44 * 解析条码数据
45 * @param buff 条码结果数据
46 * @return byte[] 条码源数据
47 */
48 public byte[] parseData(byte[] buff) throws BarcodeException;
49 }
BarcodeImpl定义抽象类，对常用属性进行初始化设置
1 package com.xqrj.barcode;

3 public abstract class BarcodeImpl implements IBarcode {
4 protected float width = 98;
5 protected float height = 98;
6 protected String imgType = "JPG";
7 protected String barcodeType = "pdf417";
8
9 public void setHeight(float height) {
10 this.height = height;
11 }
12
13 public void setImgType(String imgType) {
14 this.imgType = imgType;
15 }
16
17 public void setBarcodeType(String barcodeType) {
18 this.barcodeType = barcodeType;
19 }
20
21 public void setWidth(float width) {
22 this.width = width;
23 }
24
25 }

完成生成QR类型及PDF417类型的二维条码，如想生成其它类型只要实现抽象类即可，有各自的特殊属性，直接定义，公共属性就抽象一下，呵
