Generating and Saving Barcode in Java

Introduction

Are you looking to seamlessly integrate barcode generation into your Java application? Look no further! In this step-by-step guide, we’ll walk you through the process of using Aspose.BarCode for Java to generate and save barcodes efficiently. Aspose.BarCode is a powerful Java library that simplifies barcode creation and manipulation, providing you with the tools needed to enhance your applications with barcode functionality.

Prerequisites

Before diving into the tutorial, ensure you have the following prerequisites in place:

  • Java Development Environment: Make sure you have a Java development environment set up on your machine.

  • Aspose.BarCode Library: Download and install the Aspose.BarCode library. You can find the download link here.

  • MySQL Database: Set up a MySQL database where you intend to store barcode-related information.

  • Database Connectivity: Ensure you have the necessary credentials and connectivity to interact with the MySQL database.

Import Packages

In your Java project, import the required packages for Aspose.BarCode and MySQL connectivity.

import com.aspose.barcode.EncodeTypes;
import com.aspose.barcode.generation.BarcodeGenerator;

import java.io.File;
import java.io.FileInputStream;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;

Step 1: Generate and Save Barcode

// Step 1 - Generate barcode and save temporarily in a file
String strBarCodeImage = "c:\\temp\\code39.jpg";
String strCodeText = "NOK-E71";

BarcodeGenerator generator = new BarcodeGenerator(EncodeTypes.CODE_39_STANDARD);
generator.setCodeText(strCodeText);
generator.save(strBarCodeImage);

Explanation: This step involves creating a barcode with Aspose.BarCode, setting the code text, and saving the barcode image to a specified location.

Step 2: Insert Record in MySQL Database

// Step 2 - Insert a new record in MySQL DB
Connection con = null;

// Open connection
Class.forName("com.mysql.jdbc.Driver").newInstance();
con = DriverManager.getConnection(Common.HOST_URI, Common.USERNAME, Common.PASSWORD);

// Prepare statement
PreparedStatement pre = con.prepareCall(
        "Insert INTO Product (ProductNumber, ProductName, BarCodeImage) " + "VALUES (?, ?, ?) ");

// Set product number and product name
pre.setString(1, "NOK-E71");
pre.setString(2, "Nokia E Series - E71");

// 3rd column is for barcode image. DB type is BLOB
// For saving the image, we need to create a stream from the image file
File imgFile = new File(strBarCodeImage);
FileInputStream fin = new FileInputStream(imgFile);
pre.setBinaryStream(3, fin, (int) imgFile.length());

// Execute the statement
pre.executeUpdate();
System.out.println("Insertion successful.");

// Close connection
pre.close();
con.close();

Explanation: This step involves connecting to a MySQL database and inserting a new record with product information and the associated barcode image.

Conclusion

Congratulations! You have successfully integrated Aspose.BarCode for Java into your application to generate and save barcodes. This powerful library simplifies the process, making barcode implementation a breeze.
