Как использовать AMQP с Active MQ в Mule

Как использовать AMQP с Active MQ в Mule

Привет, я работаю с Mule Any Point Studio. Я хочу определить одно имя очереди и из этой очереди я хочу читать данные с помощью AMQP. Это не опрос данных из очереди, о которой я упоминал.

Мой поток мулов: <amqp:connector name="amqpConnector" doc:name="AMQP Connector" host="localhost" port="5672" username="admin" password="admin" validateConnections="true" ></amqp:connector> <flow name="mule-ampq" doc:name="mule-ampq"> <amqp:inbound-endpoint exchangeName="AMQP.DEFAULT.EXCHANGE" queueName="newx" queueAutoDelete="true" connector-ref="amqpConnector" doc:name="AMQP" exchangeType="fanout" responseTimeout="10000"/> <logger message="#[message.payload]" level="INFO" doc:name="Logger"/> </flow>

Я получаю следующую ошибку:

Попробуйте этот пример... Он содержит другой тип обмена, используемый AMQP . Для Direct Messaging вам не нужно явно создавать очередь в RabitMQ... она будет создана автоматически:

<http:connector name="HttpConnector" doc:name="HTTP\HTTPS"/>

    <amqp:connector name="amqpConnector" activeDeclarationsOnly="true" ackMode="MULE_AUTO" doc:name="AMQP Connector"/>

    <amqp:connector name="amqpConnectorManualAck" prefetchCount="1"  ackMode="MANUAL" doc:name="AMQP Connector"/>

    <amqp:connector name="mandatoryAmqpConnector" mandatory="true" immediate="true" doc:name="AMQP Connector"/>


   <!-- Direct Messaging -->
   <amqp:connector name="amqp_config" validateConnections="true" virtualHost="/"  username="guest" password="guest" doc:name="AMQP Connector"/>
