Spring kafka消息驱动适配器不工作

要使用kafka:消息驱动的通道适配器使用消息

在以下通道中生成消息： 标题['topic']=inMsge\u主题，emailMesge\u主题

在互联网上也找不到类似的好例子。请建议

使用时工作正常
int kafka:入站通道适配器，但它需要轮询。（希望不进行轮询）

以下是使用的配置：

 <int-kafka:outbound-channel-adapter id="kafkaOutboundChannelAdapter" kafka-producer-context-ref="kafkaProducerContext"
                                                                 auto-startup="true" channel="inputToKafka" message-key="kafka_messageKey">
          <int:poller fixed-delay="1000" time-unit="MILLISECONDS" receive-timeout="0" task-executor="taskExecutor" /> 
   </int-kafka:outbound-channel-adapter>

   <int-kafka:producer-context id="kafkaProducerContext"
          producer-properties="producerProperties">
          <int-kafka:producer-configurations>
                <int-kafka:producer-configuration
                       broker-list="${kafka.producer.brokerList}" topic="headers['topic']" key-class-type="java.lang.String"
                       value-class-type="com.vo.MessageVO"
                       value-encoder="kafkaEncoder" key-encoder="kafkaKeyEncoder"
                       compression-type="none" />
          </int-kafka:producer-configurations>
   </int-kafka:producer-context>    
   <int:channel id="inputToKafka">
     <int:queue />
   </int:channel>

  <int:channel id="inputFromKafka">
   </int:channel>
 <bean id="kafkaConfiguration" class="org.springframework.integration.kafka.core.ZookeeperConfiguration">
   <constructor-arg ref="zookeeperConnect"/>

看看-它使用Java配置而不是XML，但同时显示出站适配器和消息驱动适配器。

你好，谢谢你的建议。。kafkaMessageDrivenChannelAdapter.setOutputChannel（received（））@Bean public PollableChannel received（）{return new QueueChannel（）；}是否要轮询消息？正在查找侦听器配置。我们也可以使用PublishSubscribeChannel/DirectChannel等。是吗？True。你可以。“kafkaMessageDrivenChannelAdapter.setOutputChannel（received（））；”表示从卡夫卡主题检索后将发送消息的位置。Hi@Artem感谢您的建议。尝试上面提到的Java配置示例/链接，在这里得到错误提示。(). 请提出建议。看起来您应该开始一个新问题，并就此事分享您的web应用程序配置。您可以仅从单独的上下文中使用
