Chapter 8. AWS 2 Simple Notification System (SNS)


Send messages to an AWS Simple Notification Topic using AWS SDK version 2.x.

8.1. What’s inside

Please refer to the above link for usage and configuration details.

8.2. Maven coordinates

Create a new project with this extension on code.quarkus.redhat.com

Or add the coordinates to your existing project:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-aws2-sns</artifactId>
</dependency>
Copy to Clipboard Toggle word wrap

8.3. SSL in native mode

This extension auto-enables SSL support in native mode. Hence you do not need to add quarkus.ssl.native=true to your application.properties yourself. See also Quarkus SSL guide.

8.4. Additional Camel Quarkus configuration

If desired, it is possible to use the Quarkus Amazon SNS extension in conjunction with Camel Quarkus AWS 2 Simple Notification System (SNS). Note that this is fully optional and not mandatory at all. Please follow the Quarkus documentation but beware of the following caveats:

  1. The client type apache has to be selected by configuring the following property:

    quarkus.sns.sync-client.type=apache
    Copy to Clipboard Toggle word wrap
  2. The SnsClient has to be made "unremovable" in the sense of Quarkus CDI reference so that Camel Quarkus is able to look it up at runtime. You can reach that e.g. by adding a dummy bean injecting SnsClient:

    import javax.enterprise.context.ApplicationScoped;
    import io.quarkus.arc.Unremovable;
    import software.amazon.awssdk.services.sns.SnsClient;
    
    @ApplicationScoped
    @Unremovable
    class UnremovableSnsClient {
        @Inject
        SnsClient snsClient;
    }
    Copy to Clipboard Toggle word wrap
