Java based on Maven to realize zxing generation of two-dimensional code __java

The code is as follows:
1.maven Jar Required

<dependency>
   <groupId>com.google.zxing</groupId>
   <artifactid>core</ artifactid>
   <version>3.0.0</version>
   </dependency>
   <dependency>
   <groupId>com.google.zxing</groupId>
   <artifactId>javase</artifactId>
   < Version>3.0.0</version>  
</dependency>

2. Generate two-dimensional code:

Package com;
Import Java.io.File;
Import java.io.IOException;
Import Java.nio.file.Path;
Import java.util.Hashtable;
Import Com.google.zxing.BarcodeFormat;
Import Com.google.zxing.EncodeHintType;
Import Com.google.zxing.MultiFormatWriter;
Import com.google.zxing.WriterException;
Import Com.google.zxing.client.j2se.MatrixToImageWriter;
Import Com.google.zxing.common.BitMatrix;

Import Com.google.zxing.qrcode.decoder.ErrorCorrectionLevel;
    public static void Main (string[] args) throws IOException {String text= "www.baidu.com";
    int width=100;
    int height=100;
    String format= "PNG";
    Hashtable hints=new Hashtable ();
    Hints.put (Encodehinttype.character_set, "utf-8");
    Hints.put (Encodehinttype.error_correction, ERRORCORRECTIONLEVEL.M);
    Hints.put (Encodehinttype.margin, 2);
     try {Bitmatrix bitmatrix=new multiformatwriter (). Encode (text, Barcodeformat.qr_code, width, height,hints); Path file=new Java.io.File ("D:/new.png"). Topath ()//Generate two-dimensional code picture in D disk MatrixtoimAgewriter.writetopath (Bitmatrix, format, file); catch (Writerexception e) {//TODO auto-generated catch block E.printstacktrace ();}

3. Parsing two-dimensional code:

Package com;
Import Java.awt.image.BufferedImage;
Import Java.io.File;
Import java.io.IOException;
Import java.util.Hashtable;
Import Javax.imageio.ImageIO;
Import Com.google.zxing.BinaryBitmap;
Import Com.google.zxing.EncodeHintType;
Import Com.google.zxing.MultiFormatReader;
Import com.google.zxing.NotFoundException;
Import Com.google.zxing.Result;
Import Com.google.zxing.client.j2se.BufferedImageLuminanceSource;

Import Com.google.zxing.common.HybridBinarizer; public static void Main (string[] args) throws notfoundexception {Multiformatreader formatreader=new multiformatreader
    ();
    File file =new file ("D:/new.png");
    BufferedImage Image=null;
    try {image = Imageio.read (file);
    catch (IOException e) {//TODO auto-generated catch block E.printstacktrace ();
    } binarybitmap binarybitmap =new binarybitmap (new Hybridbinarizer (image));
    Hashtable hints=new Hashtable (); Hints.put (Encodehinttype.character_set, "UTF-8 ");
    Result Result=formatreader.decode (binarybitmap,hints);
    System.err.println ("Analytic Result:" +result.tostring ());
    System.out.println (Result.getbarcodeformat ());
System.out.println (Result.gettext ()); }
