Java中基于maven实现zxing二维码功能

maven所需jar

<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>

生成二维码：

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();
matrixtoimagewriter.writetopath(bitmatrix, format, file);
} catch (writerexception e) {
// todo auto-generated catch block
e.printstacktrace();
}
解析二维码：
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(new bufferedimageluminancesource(image)));
hashtable hints=new hashtable();
hints.put(encodehinttype.character_set, "utf-8");
result result=formatreader.decode(binarybitmap,hints);
system.err.println("解析结果："+result.tostring());
system.out.println(result.getbarcodeformat());
system.out.println(result.gettext());
}

以上所述是小编给大家介绍的java中基于maven实现zxing二维码功能，希望对大家有所帮助
