Usage

From source file:org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer.java

protected BlockingQueueConsumer createBlockingQueueConsumer() {
    BlockingQueueConsumer consumer;/*from   w w w  .j  a v  a2 s .  c  o m*/
    String[] queues = getRequiredQueueNames();
    // There's no point prefetching less than the tx size, otherwise the consumer will stall because the broker
    // didn't get an ack for delivered messages
    int actualPrefetchCount = getPrefetchCount() > this.txSize ? getPrefetchCount() : this.txSize;
    consumer = new BlockingQueueConsumer(getConnectionFactory(), this.messagePropertiesConverter,
            this.cancellationLock, getAcknowledgeMode(), isChannelTransacted(), actualPrefetchCount,
            isDefaultRequeueRejected(), getConsumerArguments(), isExclusive(), queues);
