The use of Java three-party---->zxing Framework

Today we are going to learn about the usage of zxing, which only covers the Java SE section.

The study of Zxing

If you use zxing in a Java SE environment, you need to add dependencies in Maven's pom.xml:

<Dependency>    <groupId>Com.google.zxing</groupId>    <Artifactid>Javase</Artifactid>    <version>3.3.0</version></Dependency>

First, according to the content to generate two-dimensional code

 Public void Encodenoreturn (String content) {    try  {        new File ("File/huhx.png"). Topath ();         New Multiformatwriter (). Encode (content, Barcodeformat.qr_code, +);        " PNG ", Path);     Catch (Exception e) {        e.printstacktrace ();    }}

Second, according to the QR code to read the content

 Public Static voidMain (string[] args) {File file=NewFile ("File/huhx.jpg"); BufferedImage BufferedImage=NULL; Try{bufferedimage=imageio.read (file); } Catch(IOException e) {e.printstacktrace (); } Luminancesource Source=NewBufferedimageluminancesource (BufferedImage); Binarybitmap Bitmap=NewBinarybitmap (NewHybridbinarizer (source)); Hashtable<decodehinttype, string> hints =NewHashtable<decodehinttype, string>(); Hints.put (Decodehinttype.character_set,"GBK"); Result result=NULL; Try{result=NewMultiformatreader (). Decode (bitmap, hints); } Catch(notfoundexception e) {e.printstacktrace (); } String URL=Result.gettext (); System.out.println (URL);}
