Java uses barcode4j to generate barcodes

1. The jar package that will be used to import the project (1, Commons-lang-2.3.jar 2, Barcode4j-light-2.0.jar)

2. New Class Barcodeutil

3. Code part

Import Java.io.File;
Import java.io.FileNotFoundException;
Import Java.io.FileOutputStream;

Barcode type

Fine degree

Module width
Final double modulewidth = unitconv.in2mm (2.0f/dpi);

Configuration objects

Output to stream

Generate barcodes

4. Calling interface

/**
* Barcode Generation
* @author Saffi
* @throws IOException
*/
@RequestMapping ("Testorderbarcodes.action")
Public @ResponseBody String testorderbarcodes (HttpServletResponse respon) throws IOException {
String result= "Error";
try {

Calling interface
Barcodeutil util = new Barcodeutil ();

Barcode Content
String msg = ' Te123456 ';
Path
String Path = "C:/users/administrator/desktop/barcode/barcode" +msg+ ". png";
Util.generatefiles (msg, path);

result= "SUCC";
} catch (Exception e) {
E.printstacktrace ();
Respon.sendredirect ("Error.action");
Log.error ("System error", E.fillinstacktrace ());
}
return result;
}
