Integrate Microsoft Azure Cognitive Services Form Recognizer API in Java
- **Import Required Libraries and Dependencies**
You need to include Azure Form Recognizer's client libraries in your project. Utilize Maven for dependency management to simplify the process.
<dependency>
<groupId>com.azure</groupId>
<artifactId>azure-ai-formrecognizer</artifactId>
<version>3.1.3</version>
</dependency>
- **Configure Client Authentication**
Initialize the `FormRecognizerClient` by setting up the credentials. You will need the `Endpoint URL` and the `API Key` from the Azure portal.
- **Code Implementation**
Use the client to interact with the Form Recognizer API. Below is a sample Java code to initiate the client and analyze forms.
import com.azure.ai.formrecognizer.FormRecognizerClient;
import com.azure.ai.formrecognizer.FormRecognizerClientBuilder;
import com.azure.ai.formrecognizer.models.FormPage;
import com.azure.core.credential.AzureKeyCredential;
import java.util.List;
public class FormRecognizerExample {
public static void main(String[] args) {
FormRecognizerClient formRecognizerClient = new FormRecognizerClientBuilder()
.credential(new AzureKeyCredential("<YOUR_API_KEY>"))
.endpoint("<YOUR_ENDPOINT>")
.buildClient();
String formUrl = "<YOUR_FORM_URL>";
List<FormPage> recognizedFormPages = formRecognizerClient.beginRecognizeContentFromUrl(formUrl)
.getFinalResult();
for (FormPage formPage : recognizedFormPages) {
System.out.printf("Page %d has width: %f and height: %f, measured with unit: %s.%n",
formPage.getPageNumber(),
formPage.getWidth(),
formPage.getHeight(),
formPage.getUnit());
}
}
}
- **Handle Asynchronous Operations**
The Form Recognizer uses async operations. Ensure you handle results correctly. `beginRecognizeContentFromUrl` returns a `PollerFlux` to manage operations.
- **Run the Application**
Compile and run the Java application to start recognizing forms and extracting content.
- **Error Handling and Logging**
Ensure to catch exceptions and implement proper error logging for production-level code.
// Example of exception handling
try {
// Your code to call Form Recognizer
} catch (Exception e) {
System.out.println("An error occurred: " + e.getMessage());
}
- **Optimize and Testing**
Test your implementation rigorously and check responses thoroughly, adjusting configurations and client settings as needed to optimize performance.
