A few lines of code to solve the Java generation parsing two-dimensional code function

Recently, the company asked to scan the QR code and generate two-dimensional code functions. And some netizens in the group also mentioned. I wrote a demo here to share with you. The code is very brief, I hope you can enjoy it.

Netizens said in the online search a lot, found not the code is not complete, that is, jar mismatch.

I have shared a zxing version of the 2.2 example, also provided. The implementation code is as follows:

Package Com.herman.test;import Java.io.file;import Java.io.fileinputstream;import java.io.FileNotFoundException; Import Java.io.ioexception;import java.util.hashmap;import Java.util.map;import Javax.imageio.imageio;import Com.google.zxing.barcodeformat;import Com.google.zxing.binarybitmap;import Com.google.zxing.DecodeHintType; Import Com.google.zxing.encodehinttype;import Com.google.zxing.multiformatreader;import Com.google.zxing.multiformatwriter;import Com.google.zxing.notfoundexception;import Com.google.zxing.writerexception;import Com.google.zxing.client.j2se.bufferedimageluminancesource;import Com.google.zxing.client.j2se.matrixtoimagewriter;import Com.google.zxing.common.hybridbinarizer;import com.google.zxing.qrcode.decoder.errorcorrectionlevel;/** * QR Code tool class * @author Herman.xiong * @date 2015-7-10 10:52:15 * @ Version V3.0 * @since JDK 1.6,tomcat 6.0 */public class Zxingutil {private static final Map<encodehinttype, Errorcorrec tionlevel> Encodemap = new Hashmap<encodehiNttype, errorcorrectionlevel> ();p rivate static final Map<decodehinttype, errorcorrectionlevel> decodeMap= New Hashmap<decodehinttype, errorcorrectionlevel> ();p rivate static final String charset= "UTF-8", format= "PNG"; private static final int size=150;private Zxingutil () {}/** * Generate two-dimensional code picture * @author Herman.xiong * @date 2015-7-10 10:26:33 * @param file * @throws writerexception * @throws ioexception */public static void Createqrcode (String data, file file) thr oWS writerexception, IOException {matrixtoimagewriter.writetofile (New Multiformatwriter ().

The results are as follows:
