java - Spring-Boot AMQP 1.3.1.RELEASE - 持久队列

Question

由于某种原因，即使我在 Spring AMQP 队列配置中指定了该设置，我的队列也没有创建为持久的:

@Bean
Queue queue() {
    //durable queue - true
    return new Queue(queueName, true);
}

我正在使用 Spring AMQP 连接到 RabbitMQ 并在直接交换上监听该队列。

@Bean
DirectExchange exchange() {
    return new DirectExchange(exchangeName);
}

@Bean
Binding binding(Queue queue, DirectExchange exchange) {
    return BindingBuilder.bind(queue).to(exchange).with(queueName);
}

@Bean
public ConnectionFactory connectionFactory() {

    CloudFactory cloudFactory = new CloudFactory();
    Cloud cloud = cloudFactory.getCloud();

    AmqpServiceInfo serviceInfo = (AmqpServiceInfo) 
            cloud.getServiceInfo(serviceName);

    CachingConnectionFactory connectionFactory =
        new CachingConnectionFactory(serviceInfo.getHost());
    connectionFactory.setUsername(serviceInfo.getUserName());
    connectionFactory.setPassword(serviceInfo.getPassword());
    connectionFactory.setVirtualHost(serviceInfo.getVirtualHost());
    return connectionFactory;
}

@Bean
MessageListenerAdapter underwritingMessageListener() throws Exception {
    return new MessageListenerAdapter(new UnderwritingMessageListener()) {{
        setDefaultListenerMethod("onMessage");
    }};
}

@Bean
SimpleMessageListenerContainer container(ConnectionFactory connectionFactory, 
        MessageListenerAdapter underwritingMessageListener) {
    SimpleMessageListenerContainer container = new SimpleMessageListenerContainer();
    container.setConnectionFactory(connectionFactory);
    container.setQueueNames(queueName);
    container.setMessageListener(underwritingMessageListener);
    return container;
}

我是否缺少配置步骤？

该设置未生效，因为在部署上述代码之前队列已存在，但不持久。通过管理控制台或 CLI 删除队列，允许应用程序将队列声明为持久队列(重新启动后)。

如果 Spring-AMQP (RabbitMQ) 在队列已声明为不同状态时抛出异常而不是继续进行无效部署，将会很有帮助。
