Question

我想用最新的Spring版本为Spring AMQP注册两个队列侦听器：

    @Bean
    public SimpleMessageListenerContainer processingTransactionSaleContainer(ConnectionFactory cf, TransactionElavonSaleListener listener) {
        SimpleMessageListenerContainer container = new SimpleMessageListenerContainer(cf);
        container.setQueueNames(QUEUE_PROCESSING_SALE);
        container.setMessageListener(new MessageListenerAdapter(listener, "transactionSaleProcess"));
        container.setMessageConverter(new SerializerMessageConverter());
        return container;
    }

    @Bean
    public SimpleMessageListenerContainer processingTransactionAuthorizeContainer(ConnectionFactory cf, TransactionAuthorizeListener listener) {
        SimpleMessageListenerContainer container = new SimpleMessageListenerContainer(cf);
        container.setQueueNames(QUEUE_PROCESSING_AUTHORIZE);
        container.setMessageListener(new MessageListenerAdapter(listener, "transactionAuthorizeProcess"));
        container.setMessageConverter(new SerializerMessageConverter());
        return container;
    }

监听器：

@Component
public class TransactionElavonSaleListener {

    public TransactionResponseFactory transactionElavonSaleProcess(TransactionRequestFactory ro) {
        ..... do some heavy network request
        return parseRawSuccessResponse(response);
    }

}

当我删除其中一个SimpleMessageListenerContainer时，它是工作文件，但是当我同时使用这两种方法时，都会出现此异常：

您知道为什么当我拥有这两种方法时会得到此异常吗？

EDITL定义的侦听器：

    @Bean
    public SimpleMessageListenerContainer processingTransactionElavonSaleContainer(ConnectionFactory cf, TransactionElavonSaleListener listener) {
        SimpleMessageListenerContainer container = new SimpleMessageListenerContainer(cf);
        container.setQueueNames(QUEUE_PROCESSING_ELAVON_SALE);
        container.setMessageListener(new MessageListenerAdapter(listener, "transactionElavonSaleProcess"));
        return container;
    }

    @Bean
    public SimpleMessageListenerContainer processingTransactionElavonAuthorizeContainer(ConnectionFactory cf, TransactionElavonAuthorizeListener listener) {
        SimpleMessageListenerContainer container = new SimpleMessageListenerContainer(cf);
        container.setQueueNames(QUEUE_PROCESSING_ELAVON_AUTHORIZE);
        container.setMessageListener(new MessageListenerAdapter(listener, "transactionElavonAuthorizeProcess"));
        return container;
    }

...

@Component
public class TransactionElavonSaleListener {

    public TransactionResponseFactory transactionElavonSaleProcess(TransactionRequestFactory ro) {

        return new TransactionResponseFactory();
    }
}


@Component
public class TransactionElavonAuthorizeListener {

    public TransactionResponseFactory transactionElavonAuthorizeProcess(TransactionRequestFactory tf) {

        TransactionResponseFactory obj = new TransactionResponseFactory();                  
        return obj;
    }
}

发送对象：

TransactionResponseFactory processingPeply = (TransactionResponseFactory) processingTransactionElavonAuthorizeTemplate.convertSendAndReceive(
        ContextServer.EXCHANGE_PROCESSING, ContextServer.ROUTING_KEY_PROCESSING_TRANSACTION_ELAVON, tf);
    System.out.println("!!!!! Received PROCESSING_TRANSACTION " + processingPeply.getTransaction_id());

关于您的配置的观察（但是与您的问题无关）...

您的declare...中的AmqpAdmin代码不是必需的。
- 您应该在bean定义阶段切勿与代理进行交互-为时过早。
- 它们不是必需的，因为管理员会找到Queue和Exchange bean，并在首次打开连接时自动为您声明它们。

是的，该消息转换器设置器不用于此类侦听器；消息转换器应该设置在MessageListenerAdapter上。

但是，默认情况下它会得到一个SimpleMessageConverter，所以这不是问题。该转换器处理序列化的对象以及纯文本。

现在，到您的实际问题；添加第二个容器不会对客户端产生任何影响；每个模板都有自己的回复容器，默认情况下使用直接回复，因此它们之间不会发生串扰（如果您使用命名的回复队列，则可能会发生这种情况，但实际情况并非如此）。

我建议您打开DEBUG日志记录以了解发生的情况；如果您需要帮助分析它们；发布日志（从客户端和服务器端），我看看。

您的绑定不正确：

@Bean
public Binding bindingQueueProcessingElavonSale() {
    return BindingBuilder.bind(new Queue(QUEUE_PROCESSING_ELAVON_SALE, true))
            .to(new TopicExchange(EXCHANGE_PROCESSING)).with(ROUTING_KEY_PROCESSING_TRANSACTION_ELAVON);
}

@Bean
public Binding bindingQueueProcessingElavonAuthorize() {
    return BindingBuilder.bind(new Queue(QUEUE_PROCESSING_ELAVON_AUTHORIZE, true))
            .to(new TopicExchange(EXCHANGE_PROCESSING)).with(ROUTING_KEY_PROCESSING_TRANSACTION_ELAVON);
}

您将两个队列都绑定到具有相同路由密钥的同一交换机上-RabbitMQ会将带有该路由密钥的消息发送到两个队列，因此两个侦听器都会响应。

convertSendAndReceive的默认超时为5秒。要将replyTimeout的超时设置属性AmqpTemplate修改为更大的值（毫秒）。
