How to generate a EAN-8 barcode as a PNG file in Java

Barcode generation in Java is a bit of a tricky task if gone about with a manual approach. Quite a bit of code is required and it’s probably going to take all day. As a nice alternative to this slog, this post is covering a much simpler means of getting the same results using an API.

Before we do anything else, we need to import our library. First add this repository reference:

<repositories>
    <repository>
        <id>jitpack.io</id>
        <url>https://jitpack.io</url>
    </repository>
</repositories>

Next, our dependency reference.

<dependencies>
<dependency>
    <groupId>com.github.Cloudmersive</groupId>
    <artifactId>Cloudmersive.APIClient.Java</artifactId>
    <version>v3.54</version>
</dependency>
</dependencies>

And last, but not least, our function call for barcode generation.

// Import classes:
//import com.cloudmersive.client.invoker.ApiClient;
//import com.cloudmersive.client.invoker.ApiException;
//import com.cloudmersive.client.invoker.Configuration;
//import com.cloudmersive.client.invoker.auth.*;
//import com.cloudmersive.client.GenerateBarcodeApi;
ApiClient defaultClient = Configuration.getDefaultApiClient();
// Configure API key authorization: Apikey
ApiKeyAuth Apikey = (ApiKeyAuth) defaultClient.getAuthentication("Apikey");
Apikey.setApiKey("YOUR API KEY");
// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)
//Apikey.setApiKeyPrefix("Token");
GenerateBarcodeApi apiInstance = new GenerateBarcodeApi();
String value = "value_example"; // String | Barcode value to generate from
try {
File result = apiInstance.generateBarcodeEAN8(value);
System.out.println(result);
} catch (ApiException e) {
System.err.println("Exception when calling GenerateBarcodeApi#generateBarcodeEAN8");
e.printStackTrace();
}

Already finished.
