Prerequisites to create Domain Topic and Event Subscription using java SDK

  • JDK with version 8 or above
  • Azure subscription
  • Event Grid Topic or Domain Following steps for creating a Topic & Domain (Azure CLI)
#create Topic
az eventgrid topic create --location <location> --resource-group <your-resource-group-name> --name <your-resource-name>

#create Domain
az eventgrid domain create --location <location> --resource-group <your-resource-group-name> --name <your-resource-name>

Include the Required Packages

Add BOM file:

Include the azure-sdk-bom to your project to take a dependency on GA version of the Library.

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>com.azure</groupId>
            <artifactId>azure-sdk-bom</artifactId>
            <version>{bom_version_to_target}</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

And add the direct dependency in the dependencies section without the version flag

<dependencies>
  <dependency>
    <groupId>com.azure</groupId>
    <artifactId>azure-messaging-eventgrid</artifactId>
  </dependency>
</dependencies>

Authenticate the Client

The authentication can be either a key credential, a shared access signature, or Azure Active Directory token authentication. Refer here

Create the client

Using endpoint and Access key to create the client

// For custom event
EventGridPublisherAsyncClient<BinaryData> customEventAsyncClient = new EventGridPublisherClientBuilder()
    .endpoint("<endpoint of your event grid topic/domain that accepts custom event schema>")
    .credential(new AzureKeyCredential("<key for the endpoint>"))
    .buildCustomEventPublisherAsyncClient();

Using endpoint and SAS token to create the client

EventGridPublisherAsyncClient<CloudEvent> cloudEventAsyncClient = new EventGridPublisherClientBuilder()
    .endpoint("<endpoint of your event grid topic/domain that accepts CloudEvent schema>")
    .credential(new AzureSasCredential("<sas token that can access the endpoint>"))
    .buildCloudEventPublisherAsyncClient();
