qrcode解析出來(lái)是一長(zhǎng)串?dāng)?shù)字？？求解
package com.wk.qrcode;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import jp.sourceforge.qrcode.QRCodeDecoder;
public class ReadQRCode {
public static void main(String[] args) throws IOException {
File file = new File("D://img.png");
BufferedImage bufferedImage = ImageIO.read(file);
QRCodeDecoder codeDecoder = new QRCodeDecoder();
String result = new String(codeDecoder.decode(new MyQRCodeImage(bufferedImage)));
System.out.println(result);
}
}
package com.wk.qrcode;
import java.awt.image.BufferedImage;
import jp.sourceforge.qrcode.data.QRCodeImage;
public class MyQRCodeImage implements QRCodeImage {
BufferedImage bufferedImage;
public MyQRCodeImage(BufferedImage bufferedImage) {
this.bufferedImage = bufferedImage;
}
@Override
public int getHeight() {
return bufferedImage.getHeight();
}
@Override
public int getPixel(int arg0, int arg1) {
return bufferedImage.getRGB(arg0, arg1);
}
@Override
public int getWidth() {
return bufferedImage.getWidth();
}
}
結(jié)果打印出來(lái)是：

不是編碼的問(wèn)題，還是生成的圖片有問(wèn)題，大家看那個(gè)雙重for循環(huán)gs.fillRect方法，大家如果i在外層循環(huán)，j在內(nèi)層循環(huán)（個(gè)人習(xí)慣），應(yīng)該gs.fillRect(i*3+pixoff,j*3+pixoff, 3, 3);，而不是gs.fillRect(j*3+pixoff,i*3+pixoff, 3, 3);j和i的位置問(wèn)題，我生成的圖片掃描出來(lái)idcbgp.cn，但是解析確實(shí)一串?dāng)?shù)字，發(fā)現(xiàn)i和j寫(xiě)反了

同問(wèn)，我也沒(méi)解決
2016-08-07
String result = new String(codeDecoder.decode(new MyQRCodeImage(bufferedImage)));
將這句代碼修改為
String result = new String(codeDecoder.decode(new MyQRCodeImage(bufferedImage)),"gb2312");
解析出來(lái)的內(nèi)容沒(méi)有設(shè)置編碼格式
