container factory. Similarly, if a `ErrorHandler` or `AfterRollbackProcessor` bean is
defined, it is automatically associated to the default factory.
Depending on the listener type, a `RecordMessageConverter` or `BatchMessageConverter` bean
is associated to the default factory. If only a `RecordMessageConverter` bean is present
for a batch listener, it is wrapped in a `BatchMessageConverter`.
TIP: A custom `ChainedKafkaTransactionManager` must be marked `@Primary` as it usually
references the auto-configured `KafkaTransactionManager` bean.
