想使用kafka：message-driven-channel-adapter消费消息。
在以下渠道中制作讯息： headers ['topic'] = inMsge_topic，emailMesge_topic
在互联网上也没有找到同样的好例子。请建议。
使用时工作正常 int-kafka：inbound-channel-adapter但它需要轮询。（想要不进行轮询）
以下配置使用：
<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>
