Utilizzo di Java Message Service con altri client Amazon SQS

L'utilizzo del client Amazon SQS Java Message Service (JMS) con l' AWS SDK limita la dimensione dei messaggi Amazon SQS a 256 KB. Tuttavia, è possibile creare un provider JMS utilizzando qualsiasi client Amazon SQS. Ad esempio, puoi utilizzare il client JMS con la libreria client ampia di Amazon SQS per Java per inviare un messaggio Amazon SQS che contiene un riferimento a un payload del messaggio (fino a 2 GB) in Amazon S3. Per ulteriori informazioni, consulta Gestione di messaggi Amazon SQS di grandi dimensioni con Java e Amazon S3.

Il seguente codice Java di esempio crea il provider JMS per la libreria client ampia:

AmazonS3 s3 = new AmazonS3Client(credentials);
Region s3Region = Region.getRegion(Regions.US_WEST_2);
s3.setRegion(s3Region);
 
// Set the Amazon S3 bucket name, and set a lifecycle rule on the bucket to
// permanently delete objects a certain number of days after each object's creation date.
// Next, create the bucket, and enable message objects to be stored in the bucket.
BucketLifecycleConfiguration.Rule expirationRule = new BucketLifecycleConfiguration.Rule();
expirationRule.withExpirationInDays(14).withStatus("Enabled");
BucketLifecycleConfiguration lifecycleConfig = new BucketLifecycleConfiguration().withRules(expirationRule);
 
s3.createBucket(s3BucketName);
s3.setBucketLifecycleConfiguration(s3BucketName, lifecycleConfig);
System.out.println("Bucket created and configured.");

// Set the SQS extended client configuration with large payload support enabled.
ExtendedClientConfiguration extendedClientConfig = new ExtendedClientConfiguration()
    .withLargePayloadSupportEnabled(s3, s3BucketName);
 
AmazonSQS sqsExtended = new AmazonSQSExtendedClient(new AmazonSQSClient(credentials), extendedClientConfig);
Region sqsRegion = Region.getRegion(Regions.US_WEST_2);
sqsExtended.setRegion(sqsRegion);

Il seguente codice Java di esempio crea la connection factory:

// Create the connection factory using the environment variable credential provider.
// Pass the configured Amazon SQS Extended Client to the JMS connection factory.
SQSConnectionFactory connectionFactory = new SQSConnectionFactory(
        new ProviderConfiguration(),
        sqsExtended
        );
 
// Create the connection.
SQSConnection connection = connectionFactory.createConnection();
