Java Spring Boot Kafka嵌入Kafka事务

嗨，我想用卡夫卡测试卡夫卡消费者方法。我有这个方法：

@KafkaListener(topics = TOPIC_OWNER)
@Transactional("chainedKafkaTransactionManager")
public void consumeFromOwnerTopic(ConsumerRecord<String, AccessAvro> accessAvro) {
    final UUID userId = textMapper.toUUID(accessAvro.value().getUserId());
    User user = getUserFromDatabase(userId);
    userRepository.save(user);
    }
}

@KafkaListener（topics=TOPIC\u所有者）
@事务性（“chainedKafkaTransactionManager”）
public void consumerfromOwnerTopic（ConsumerRecord accessAvro）{
最终UUID userId=textMapper.touid（accessAvro.value（）.getUserId（））；
User User=getUserFromDatabase（userId）；
userRepository.save（用户）；
}
}

试验

@SpringBootTest
@ActiveProfiles（“测试”）
@TestPropertySource（locations=“classpath:bootstrap test.yml”）
@EmbeddedKafka（partitions=1，topics=“access owner”，bootstrapServersProperty=
“spring.kafka.bootstrap服务器”）
类AccessConsumerTest扩展了规范{
@自动连线
私有KafkaTemplate模板
准备访问访问访问访问访问（）{
AccessAvro AccessAvro=新AccessAvro（）；
accessAvro.restaurantId=UUID.randomuid（）.toString（）
accessAvro.userId=UUID.randomUUID（）.toString（）
返回存取器
}
def“应该从已使用的主题添加角色”（）{
鉴于：
sendKafkaAcces（）
期望：
1==1
}
私有上市未来sendKafkaAcces（）{
发送（“访问所有者”，prepareAccessAvro（））
}

}

在以下情况下，我的交易有错误：

• 我将注释@Transaction（“链接…”）添加到测试方法中，我对副本有错误
• 尝试删除“transaction id prefix”表单属性，我对ChainedKafkatTransaction.class bc有错误。正在尝试在属性中查找它
• 当我尝试不在测试方法上添加@Transaction时，出现错误：在事务中运行 我如何测试它

原因：org.springframework.beans.factory.NoSuchBeanDefinitionException:没有类型为“org.springframework.kafka.transaction.KafkaTransactionManager”的合格bean可用：至少需要1个符合autowire候选条件的bean。依赖项注释：{}

有什么错误？

No transaction is in process; possible solutions: run the template operation within the scope of a template.executeInTransaction() operation, start a transaction with @Transactional before invoking the template method, run in a transaction started by a listener container when consuming a record
