Class QueueServiceClientBuilder

  • public final class QueueServiceClientBuilder
extends Object
    This class provides a fluent builder API to help aid the configuration and instantiation of the queueServiceClients and queueServiceAsyncClients, calling buildClient constructs an instance of QueueServiceClient and calling buildAsyncClient constructs an instance of QueueServiceAsyncClient.

    The client needs the endpoint of the Azure Storage Queue service, name of the share, and authorization credential. endpoint gives the builder the endpoint and may give the builder the a SAS token that authorizes the client.

    Instantiating a synchronous Queue Service Client with SAS token

     QueueServiceClient client = new QueueServiceClientBuilder()
     .endpoint("https://${accountName}.queue.core.windows.net?${SASToken}")
     .buildClient();

    Instantiating an Asynchronous Queue Service Client with SAS token

     QueueServiceAsyncClient client = new QueueServiceClientBuilder()
     .endpoint("https://{accountName}.queue.core.windows.net?{SASToken}")
     .buildAsyncClient();

    If the endpoint doesn't contain the query parameters to construct a SAS token they may be set using sasToken together with endpoint.

    Instantiating a synchronous Queue Service Client with SAS token

     QueueServiceAsyncClient client = new QueueServiceClientBuilder()
     .endpoint("https://{accountName}.queue.core.windows.net")
     .sasToken("{SASTokenQueryParams}")
     .buildAsyncClient();

    Instantiating an Asynchronous Queue Service Client with SAS token

     QueueServiceAsyncClient client = new QueueServiceClientBuilder()
     .endpoint("https://{accountName}.queue.core.windows.net")
     .sasToken("{SASTokenQueryParams}")
     .buildAsyncClient();

    Another way to authenticate the client is using a StorageSharedKeyCredential. To create a StorageSharedKeyCredential a connection string from the Storage Queue service must be used. Set the StorageSharedKeyCredential with connectionString. If the builder has both a SAS token and StorageSharedKeyCredential the StorageSharedKeyCredential will be preferred when authorizing requests sent to the service.

    Instantiating a synchronous Queue Service Client with connection string.

     String connectionString = "DefaultEndpointsProtocol=https;AccountName={name};"
     + "AccountKey={key};EndpointSuffix={core.windows.net}";
 QueueServiceClient client = new QueueServiceClientBuilder()
     .connectionString(connectionString)
     .buildClient();

    Instantiating an Asynchronous Queue Service Client with connection string.

     String connectionString = "DefaultEndpointsProtocol=https;AccountName={name};"
     + "AccountKey={key};EndpointSuffix={core.windows.net}";
 QueueServiceAsyncClient client = new QueueServiceClientBuilder()
     .connectionString(connectionString)
     .buildAsyncClient();

      • processMessageDecodingErrorAsync

        public QueueServiceClientBuilder processMessageDecodingErrorAsync​(Function<QueueMessageDecodingError,​Mono<Void>> processMessageDecodingErrorAsyncHandler)
        Sets the asynchronous handler that performs the tasks needed when a message is received or peaked from the queue but cannot be decoded.

        Such message can be received or peaked when queue is expecting certain QueueMessageEncoding but there's another producer that is not encoding messages in expected way. I.e. the queue contains messages with different encoding.

        QueueMessageDecodingError contains QueueAsyncClient for the queue that has received the message as well as QueueMessageDecodingError.getQueueMessageItem() or QueueMessageDecodingError.getPeekedMessageItem() with raw body, i.e. no decoding will be attempted so that body can be inspected as has been received from the queue.

        The handler won't attempt to remove the message from the queue. Therefore such handling should be included into handler itself.

        The handler will be shared by all queue clients that are created from QueueServiceClient or QueueServiceAsyncClient built by this builder.

        Code Samples

         String connectionString = "DefaultEndpointsProtocol=https;AccountName={name};"
     + "AccountKey={key};EndpointSuffix={core.windows.net}";

 Function<QueueMessageDecodingError, Mono<Void>> processMessageDecodingErrorHandler =
     (queueMessageDecodingFailure) -> {
         QueueMessageItem queueMessageItem = queueMessageDecodingFailure.getQueueMessageItem();
         PeekedMessageItem peekedMessageItem = queueMessageDecodingFailure.getPeekedMessageItem();
         if (queueMessageItem != null) {
             System.out.printf("Received badly encoded message, messageId=%s, messageBody=%s",
                 queueMessageItem.getMessageId(),
                 queueMessageItem.getBody().toString());
             return queueMessageDecodingFailure
                 .getQueueAsyncClient()
                 .deleteMessage(queueMessageItem.getMessageId(), queueMessageItem.getPopReceipt());
         } else if (peekedMessageItem != null) {
             System.out.printf("Peeked badly encoded message, messageId=%s, messageBody=%s",
                 peekedMessageItem.getMessageId(),
                 peekedMessageItem.getBody().toString());
             return Mono.empty();

      • serviceVersion

        public QueueServiceClientBuilder serviceVersion​(QueueServiceVersion version)
        Sets the QueueServiceVersion that is used when making API requests.

        If a service version is not provided, the service version that will be used will be the latest known service version based on the version of the client library being used. If no service version is specified, updating to a newer version of the client library will have the result of potentially moving to a newer service version.

        Targeting a specific service version may also mean that the service will return an error for newer APIs.

        Parameters:
        version - QueueServiceVersion of the service to be used when making requests.
        Returns:
        the updated QueueServiceClientBuilder object
