我正在尝试为rabbit和kafka使用一个事务管理器。首先我从兔子的回叫中得到一条消息，然后把它发送给Kafka主题。但我总是得到一个异常，表明rabbit无法正确完成事务：

以下是rabbit listener中出现问题的方法：

@RabbitListener(queues = ["\${queue}"])
@Transactional("chainedTransactionManager")
fun receiveCallback(message: Message<List<CallbackMessage>>) {
    traceMessage(message)
    val callbacks = message.payload
    callbacks.forEach { callback ->
        kafkaService.sendAfterCallBack(Object())
    }
}

研究方法 KafkaService :

@Transactional("chainedTransactionManager")
fun sendAfterCallBack(object: Object) {
    convertAndSend(kafkaServiceProperties.topics.name, object)
}

这里是 TransactionManager 配置：

@Configuration
class TransactionManagerConfiguration {

    @Bean
    fun chainedTransactionManager(
            rabbitTransactionManager: RabbitTransactionManager,
            kafkaTransactionManager: KafkaTransactionManager<*, *>
    ): ChainedTransactionManager {
        return ChainedTransactionManager(kafkaTransactionManager, rabbitTransactionManager)
    }
}

兔子配置：

@Configuration
@EnableRabbit
@Import(RabbitAutoCreationConfiguration::class)
class RabbitConfiguration(
        private val integrationProperties: IntegrationProperties,
        private var clientProperties: RabbitClientProperties,
        private val jacksonObjectMapper: ObjectMapper
) : RabbitListenerConfigurer {

    @Bean
    fun rabbitListenerContainerFactory(connectionFactory: ConnectionFactory): SimpleRabbitListenerContainerFactory {
        val factory = SimpleRabbitListenerContainerFactory()
        factory.setConnectionFactory(connectionFactory)
        factory.setErrorHandler { t -> throw AmqpRejectAndDontRequeueException(t) }

        return factory
    }

    @Bean
    fun messageConverter(): MessageConverter {
        val messageConverter = MappingJackson2MessageConverter()
        messageConverter.objectMapper = jacksonObjectMapper

        return messageConverter
    }

    @Bean
    fun messageHandlerFactory(): MessageHandlerMethodFactory {
        val factory = DefaultMessageHandlerMethodFactory()
        factory.setMessageConverter(messageConverter())
        return factory
    }

    @Bean
    @ConditionalOnBean(CachingConnectionFactory::class)
    fun rabbitConnectionFactoryCustomizer(factory: CachingConnectionFactory): SmartInitializingSingleton {
        return SmartInitializingSingleton {
            factory.rabbitConnectionFactory.clientProperties.apply {
                clientProperties.copyright?.let { put("copyright", it) }

                put("os", System.getProperty("os.name"))
                put("host", InetAddress.getLocalHost().hostName)

                clientProperties.platform?.let { put("platform", it) }
                clientProperties.product?.let { put("product", it) }
                clientProperties.service?.let { put("service", it) }
            }
        }
    }

    override fun configureRabbitListeners(registrar: RabbitListenerEndpointRegistrar?) {
        registrar!!.messageHandlerMethodFactory = messageHandlerFactory()
    }

    @Bean
    fun rabbitTemplate(
            connectionFactory: ConnectionFactory,
            jsonObjectMapper: ObjectMapper
    ): RabbitTemplate {
        val rabbitTemplate = RabbitTemplate(connectionFactory)

        val retryTemplate = RetryTemplate()
        retryTemplate.setRetryPolicy(SimpleRetryPolicy(integrationProperties.callbackRetry))
        rabbitTemplate.setRetryTemplate(retryTemplate)
        rabbitTemplate.isChannelTransacted = true

        return rabbitTemplate
    }

    @Bean
    fun rabbitTransactionManager(connectionFactory: ConnectionFactory): RabbitTransactionManager {
        val rtm = RabbitTransactionManager(connectionFactory)
        rtm.transactionSynchronization = AbstractPlatformTransactionManager.SYNCHRONIZATION_ON_ACTUAL_TRANSACTION
        return rtm
    }
}

Kafka配置：

@Configuration
@EnableKafka
class KafkaConfiguration(
        @Qualifier("kafkaExchangeMessageConverter")
        private val messageConverter: MessagingMessageConverter
) {

    @Bean
    fun kafkaListenerContainerFactory(
            configurer: ConcurrentKafkaListenerContainerFactoryConfigurer,
            consumerFactory: ConsumerFactory<Any, Any>
    ): ConcurrentKafkaListenerContainerFactory<Any, Any> {
        val factory = ConcurrentKafkaListenerContainerFactory<Any, Any>()
        factory.setMessageConverter(messageConverter)
        configurer.configure(factory, consumerFactory)

        return factory
    }

    @Bean
    fun adminClient(kafkaAdmin: KafkaAdmin): AdminClient = AdminClient.create(kafkaAdmin.config)

    @Bean
    fun kafkaTransactionManager(
            producerFactory: ProducerFactory<*, *>
    ): KafkaTransactionManager<*, *> {
        val ktm = KafkaTransactionManager(producerFactory)

        ktm.transactionSynchronization = AbstractPlatformTransactionManager.SYNCHRONIZATION_ON_ACTUAL_TRANSACTION

        return ktm
    }
}

我错过什么了吗 RabbitConfiguration 或者问题出在别的地方？
