![]() ![]() Here you also have to add Dependency in your Mule's POM file.īelow is the Mule Code logic that I have created to call java function to generate static QR code for the string.īelow is the Mule Flow of the above mentioned XML. Return Base64 String to Calling Function ImageString = encoder.encodeToString(imageBytes) ImageIO.write(MatrixToImageWriter.toBufferedImage(matrix), "png", bos) īase64.Encoder encoder = Base64.getEncoder() ( MatrixToImageWriter.toBufferedImage(matrix)) īyteArrayOutputStream bos = new ByteArrayOutputStream() MultiFormatWriter is a factory class that finds the appropriate Writer subclass for the BarcodeFormat requested and encodes the barcode with the supplied contents.īitMatrix matrix = new MultiFormatWriter().encode(new String(data.getBytes(charset), charset), BarcodeFormat.QR_CODE, widthOfQR, heightOfQR) the BitMatrix class represents the 2D matrix of bits Public static String generateQRcode(String data, int heightOfQR, int widthOfQR) throws WriterException, IOException Here I have used JXing java library you can use other java library that supports QR code. We will provide a string to the function that can help us to convert any string(URL/String etc) to QR code.īasic flow is like, user will call our Mule API Endpoint with query parameter and inside it will call java function that is capable of creating QR Code and will return encoded string to Mulesoft it will convert to PNG format.īelow is the Java code "GenerateQrCode.java". Today I am gonna talk about second solution where we can use 3rd party java library "ZXing" that can help us to create QR code. We can create our own java function by using qr library in this case we will use ZXing and call it from Mulesoft.(have to depend on 3rd party API and can get more features). First One is we can call any 3rd Party API from HTTP requester and get QR code.I do have few approaches that can generate user provided string/URL to qr code in mule 4. To read QR codes, well be using the JavaScript port of the Java-based. Learn how we can generate QR code in Mule 4 using ZXing Java libraryĪ QR code (an abbreviated as quick response code) is a type of matrix barcode.Ĭurrently we don't have any Mule component that can generate QR code from provided String/URI in Mulesoft.Īfter looking for solutions. Scan from File: Detected QR code: Generate Download & Scan QR Code with React js. ![]()
