Document

When consuming multiple queues, set the interval between declaration attempts when only a subset of the queues were available (milliseconds).

Usage

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

protected BlockingQueueConsumer createBlockingQueueConsumer() {
    BlockingQueueConsumer consumer;
    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);
    if (this.declarationRetries != null) {
        consumer.setDeclarationRetries(this.declarationRetries);
    }/* w ww .j  ava  2 s  . c  o  m*/
    if (this.failedDeclarationRetryInterval != null) {
        consumer.setFailedDeclarationRetryInterval(this.failedDeclarationRetryInterval);
    }
    if (this.retryDeclarationInterval != null) {
        consumer.setRetryDeclarationInterval(this.retryDeclarationInterval);
    }
    if (getConsumerTagStrategy() != null) {
        consumer.setTagStrategy(getConsumerTagStrategy());
    }
    consumer.setBackOffExecution(this.recoveryBackOff.start());
    consumer.setShutdownTimeout(getShutdownTimeout());
    return consumer;
}
