Java and JS generate two-dimensional code

1. Java generates QR code

1.1 Dependent Jar package configuration (using Maven dependency)

1         <dependency> 2             <groupId>com.google.zxing</groupId> 3             <artifactid >core</artifactId> 4             <version>3.0.0</version> 5         </dependency > 6         <dependency> 7             <groupId>com.google.zxing</groupId>  8             <artifactId>javase</artifactId> 9             <version>3.0.0</version> Ten         </dependency>

1.2 Generate QR Code--zxing

1      Public Static voidCreateqrcode () {2         Try {3String content = "120605181003;HTTP://WWW.CNBLOGS.COM/JTMJX";4String Path = "D:/temp";5 6Multiformatwriter Multiformatwriter =NewMultiformatwriter ();7 8Map hints =NewHashMap ();9Hints.put (Encodehinttype.character_set, "UTF-8");TenBitmatrix Bitmatrix = multiformatwriter.encode (content, Barcodeformat.qr_code, 400, 400, hints); OneFile file1 =NewFile (Path, "Qrcode.jpg"); AMatrixtoimagewriter.writetofile (Bitmatrix, "JPG", file1); -  -System.out.println ("Successfully generated QR code"); the}Catch(Exception e) { - e.printstacktrace (); -         } -}

1.3 Parsing two-dimensional code--zxing

1      Public Static voidParseqrcode () {2         Try {3Multiformatreader Formatreader =NewMultiformatreader ();4String FilePath = "D:/temp/qrcode.jpg";5File File =NewFile (filePath);6BufferedImage image =imageio.read (file);7             ;8Luminancesource Source =NewBufferedimageluminancesource (image);9Binarizer Binarizer =NewHybridbinarizer (source);TenBinarybitmap Binarybitmap =NewBinarybitmap (binarizer); OneMap hints =NewHashMap (); AHints.put (Encodehinttype.character_set, "UTF-8"); -Result result =Formatreader.decode (Binarybitmap, hints); -  theSYSTEM.OUT.PRINTLN ("result =" +result.tostring ()); -System.out.println ("Resultformat =" +Result.getbarcodeformat ()); -System.out.println ("Resulttext =" +Result.gettext ()); -  +}Catch(Exception e) { - e.printstacktrace (); +         } A}

2. js generate two-dimensional code

2.1 Using Jquery-qrcode

Jquery-qrcode Features: Simple operation, small size, only 14k after compression, but does not support Chinese encoding.

Jquery.qrcode.min.js File Download path: http://files.cnblogs.com/files/qdwyg2013/jquery.qrcode.min.js

1<script type= "Text/javascript" src= "Http://cdn.staticfile.org/jquery/2.0.0/jquery.min.js" ></script>2<script type= "Text/javascript" src= ". /js/jquery.qrcode.min.js "></script>3<script>4         //Way One5         //$ (' #qrcode '). QRCode ("Http://www.cnblogs.com/xiyangbaixue");6         //Mode two7$ ("#qrcode"). QRCode ({8Render: "Table",//Table Mode9WIDTH:200,//widthTenHEIGHT:200,//Height OneText: "Www.baidu.com"//any Content A         }); -</script>

2.2 using QRCode

QRCode Features: Chinese-generated QR code scanning does not appear garbled, and you can choose which element to use to draw the QR code.
