  • Constructor Details

    • KafkaInboundGateway

      public KafkaInboundGateway(org.springframework.kafka.listener.AbstractMessageListenerContainer<K,V> messageListenerContainer, org.springframework.kafka.core.KafkaTemplate<K,R> kafkaTemplate)
      Construct an instance with the provided container.
      Parameters:
      messageListenerContainer - the container.
      kafkaTemplate - the kafka template.

  • Method Details

    • setMessageConverter

      public void setMessageConverter(org.springframework.kafka.support.converter.RecordMessageConverter messageConverter)
      Set the message converter; must be a RecordMessageConverter or BatchMessageConverter depending on mode.
      Parameters:
      messageConverter - the converter.

    • setPayloadType

      public void setPayloadType(Class<?> payloadType)
      When using a type-aware message converter such as StringJsonMessageConverter, set the payload type the converter should create. Defaults to Object.
      Parameters:
      payloadType - the type.

    • setRetryTemplate

      public void setRetryTemplate(org.springframework.retry.support.RetryTemplate retryTemplate)
      Specify a RetryTemplate instance to use for retrying deliveries.

      IMPORTANT: This form of retry is blocking and could cause a rebalance if the aggregate retry delays across all polled records might exceed the max.poll.interval.ms. Instead, consider adding a DefaultErrorHandler to the listener container, configured with a KafkaErrorSendingMessageRecoverer.

      Parameters:
      retryTemplate - the RetryTemplate to use.

    • setRecoveryCallback

      public void setRecoveryCallback(org.springframework.retry.RecoveryCallback<?> recoveryCallback)
      A RecoveryCallback instance for retry operation; if null, the exception will be thrown to the container after retries are exhausted (unless an error channel is configured). Only used if setRetryTemplate(RetryTemplate) is specified. Default is an ErrorMessageSendingRecoverer if an error channel has been provided. Set to null if you wish to throw the exception back to the container after retries are exhausted.
      Parameters:
      recoveryCallback - the recovery callback.

    • setOnPartitionsAssignedSeekCallback

      public void setOnPartitionsAssignedSeekCallback(BiConsumer<Map<org.apache.kafka.common.TopicPartition,Long>,org.springframework.kafka.listener.ConsumerSeekAware.ConsumerSeekCallback> onPartitionsAssignedCallback)
      Specify a BiConsumer for seeks management during ConsumerSeekAware.onPartitionsAssigned(Map, ConsumerSeekAware.ConsumerSeekCallback) call from the KafkaMessageListenerContainer. This is called from the internal MessagingMessageListenerAdapter implementation.
      Parameters:
      onPartitionsAssignedCallback - the BiConsumer to use
      See Also:
      • ConsumerSeekAware.onPartitionsAssigned(java.util.Map<org.apache.kafka.common.TopicPartition, java.lang.Long>, org.springframework.kafka.listener.ConsumerSeekAware.ConsumerSeekCallback)

    • setBindSourceRecord

      public void setBindSourceRecord(boolean bindSourceRecord)
      Set to true to bind the source consumer record in the header named IntegrationMessageHeaderAccessor.SOURCE_DATA.
      Parameters:
      bindSourceRecord - true to bind.
