我对使用spring cloud stream和kafka的服务有问题。该服务一直运行良好，但昨天开始报告启动时的一系列异常：

            at org.springframework.integration.channel.AbstractSubscribableChannel.doSend(AbstractSubscribableChannel.java:77)

一段时间后，我们就会看到这样的异常：

Caused by: org.springframework.messaging.core.DestinationResolutionException: failed to look up MessageChannel with name '946859a6-bc27-466d-91ba-3da93af50ac9:1' in the BeanFactory.; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named '946859a6-bc27-466d-91ba-3da93af50ac9:1' available

到kafka的连接配置了一个属性：spring.kafka.bootstrap-server = kafka.kafka:9092

并使用spring云流属性配置主题：spring.cloud.stream.bindings.[topic-name].destination = blah

与kafka的交互通过spring集成，代码如下：

@MessagingGateway
public interface StreamGateway {

    @Gateway(requestChannel = KafkaConfig.ENRICH_PAYMENT, replyChannel = ChannelNames.PAYMENT_REPLY, replyTimeout = 10000)
    String processPayment(String payload);

}

//不同的类：

private final StreamGateway gateway;
...
gateway.processPayment(message)

这是在azure kubernetes部署上运行的，而kafka在一个独立于spring启动服务的pod中。

提前谢谢。

更新：问题再次出现，一些进一步的调查突出了一些事情

subscriber

The
因为我们使用spring集成@MessagingGateway和@Gateway来创建与Kafka的同步交互，所以没有正常的topic StreamListener，或者当topic上有 lag 时会出现

问题，即topic中存在超出topic offset的消息。

缺少正常的<StreamListener>D19>表示无法处理lag消息。只有当MessageGateway建立连接时，才有可能从主题中读取消息。
解决此问题的一种方法是读取所有' lag‘消息，因此lag为0。然后服务将正常启动，但是如果我手动将消息发布到主题(与MessageGateway交互)，则错误再次出现。
第二个部分解决方案(我还不完全理解)是向MessageGateway添加@DependsOn注释，表明它需要一个使用@Input SubscribableChannel对象单独创建的bean。这意味着必须在MessageGateway之前创建SubscribableChannel，从而创建订阅者，但是仍然没有StreamListener，因此在从主题中提取滞后消息时仍会抛出异常，而不会出现no-where to go
