spring云流项目无法获取分区信息错误

使用此配置时：

spring:
  cloud:
    stream:
      kafka:
        binder:
          min-partition-count: 1
          replication-factor: 1
  kafka:
    producer:
      transaction-id-prefix: tx-
      retries: 1
      acks: all

我的应用程序启动正确，但在控制台输出中看到的transactional.id显示为null。为了获得正确的transactional.id，我将这个额外的配置（事务）应用于spring cloud stream：

spring:
  cloud:
    stream:
      kafka:
        binder:
          min-partition-count: 1
          replication-factor: 1
          transaction:
            transaction-id-prefix: txl-
  kafka:
    producer:
      transaction-id-prefix: tx-
      retries: 1
      acks: all

但服务未成功启动，控制台输出显示：

无法获取分区信息我认为我的配置有问题（肯定）
为了避免重复，我打算只做一次。这就是为什么我想看到那个交易id
额外信息：我的消费者使用jpa和kafka事务进行事务处理（使用chainedkafkatransactionmanager进行事务同步）
编辑：在@configuration类中，我有这些bean

@Bean
    @Primary
    fun transactionManager(em: EntityManagerFactory): JpaTransactionManager {
        return JpaTransactionManager(em)
    }

    @Bean
    fun kafkaTransactionManager(producerFactory: ProducerFactory<Any, Any>): KafkaTransactionManager<*, *> {
        return KafkaTransactionManager(producerFactory)
    }

    @Bean
    fun chainedTransactionManager(
        kafkaTransactionManager: KafkaTransactionManager<String, String>,
        transactionManager: JpaTransactionManager,
    ): ChainedKafkaTransactionManager<Any, Any> {
        return ChainedKafkaTransactionManager(kafkaTransactionManager, transactionManager)
    }

    @Bean
    fun kafkaListenerContainerFactory(
        configurer: ConcurrentKafkaListenerContainerFactoryConfigurer,
        kafkaConsumerFactory: ConsumerFactory<Any, Any>,
        chainedKafkaTransactionManager: ChainedKafkaTransactionManager<Any, Any>,
    ): ConcurrentKafkaListenerContainerFactory<*, *> {
        val factory = ConcurrentKafkaListenerContainerFactory<Any, Any>()
        configurer.configure(factory, kafkaConsumerFactory)
        factory.containerProperties.transactionManager = chainedKafkaTransactionManager
        return factory
    }

以及相应的@transactional

@EnableKafka
@EnableBinding(Channels::class)
@Service
@Transactional
class EventProcessor()
...

根据我的第一个配置，事务性同步是有效的。
我使用此日志记录配置来确认初始化事务同步和清除transactionsynchronizationmanager的事务同步。

logging:
  level:
    org.springframework.kafka: trace
    org.springframework.transaction: trace
apache-kafkaspring-cloud-streamexactly-once

看看这个答案。
您很可能没有足够的副本或同步副本用于事务日志主题。
使用 ChainedKafkaTransactionManager 只有在springcloudstream（开箱即用）中才支持生产者事务。为了 consume->produce->publishToKafka 操作，必须使用 @Transactional 在侦听器上，只使用jpa事务管理器；结果类似于事务同步。
或者，必须将正确配置的cktm注入绑定的侦听器容器。
您需要显示您的代码和其余的配置。
