Available as of Camel 2.14
The barcode data format is based on the zxing library. The goal of this component is to create a barcode image from a String (marshal) and a String from a barcode image (unmarshal). You're free to use all features that zxing offers.
To use the barcode data format in your camel routes you need to add the a dependency on camel-barcode which implements this data format.
If you use maven you could just add the following to your pom.xml, substituting the version number for the latest & greatest release (see the download page for the latest versions).
<dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-barcode</artifactId> <version>x.x.x</version> </dependency>
First you have to initialize the barcode data fomat class. You can use the default constructor, or one of parameterized (see JavaDoc). The default values are:
|image type (BarcodeImageType)||PNG|
|barcode format (BarcodeFormat)||QR-Code|
// QR-Code default DataFormat code = new BarcodeDataFormat();
If you want to use zxing hints, you can use the 'addToHintMap' method of your BarcodeDataFormat instance:
For possible hints, please consult the xzing documentation.
from("direct://code") .marshal(code) .to("file://barcode_out");
You can call the route from a test class with:
template.sendBody("direct://code", "This is a testmessage!");
You should find inside the 'barcode_out' folder this image:
The unmarshaller is generic. For unmarshalling you can use any BarcodeDataFormat instance. If you've two instances, one for (generating) QR-Code and one for PDF417, it doesn't matter which one will be used.
from("file://barcode_in?noop=true") .unmarshal(code) // for unmarshalling, the instance doesn't matter .to("mock:out");
If you'll paste the QR-Code image above into the 'barcode_in' folder, you should find '
This is a testmessage!' inside the mock. You can find the barcode data format as header variable:
|String||Value of com.google.zxing.BarcodeFormat.|
