  • Article

This how-to guide shows you how to create a WebPubSubServiceClient using Microsoft Entra ID in Java.

Requirements

  • Add azure-identity dependency in your pom.xml.

    <dependency>
  <groupId>com.azure</groupId>
  <artifactId>azure-identity</artifactId>
  <version>1.4.1</version>
</dependency>

Sample codes

  1. Create a TokenCredential with Azure Identity SDK.

    package com.webpubsub.tutorial;

import com.azure.core.credential.TokenCredential;
import com.azure.identity.DefaultAzureCredentialBuilder;

public class App {

    public static void main(String[] args) {
        TokenCredential credential = new DefaultAzureCredentialBuilder().build();
    }
}

    credential can be any class that inherits from TokenCredential class.

    • EnvironmentCredential
    • ClientSecretCredential
    • ClientCertificateCredential
    • ManagedIdentityCredential
    • VisualStudioCredential
    • VisualStudioCodeCredential
    • AzureCliCredential

  2. Then create a client with endpoint, hub, and credential.

    package com.webpubsub.tutorial;

import com.azure.core.credential.TokenCredential;
import com.azure.identity.DefaultAzureCredentialBuilder;
import com.azure.messaging.webpubsub.WebPubSubServiceClient;
import com.azure.messaging.webpubsub.WebPubSubServiceClientBuilder;

public class App {
    public static void main(String[] args) {

        TokenCredential credential = new DefaultAzureCredentialBuilder().build();

        // create the service client
        WebPubSubServiceClient client = new WebPubSubServiceClientBuilder()
                .endpoint("<endpoint>")
                .credential(credential)
                .hub("<hub>")
                .buildClient();
    }
}
