public @interface RocketMQTransactionListener

This annotation is used over a class which implements interface org.apache.rocketmq.spring.core.RocketMQLocalTransactionListener, which will be converted to org.apache.rocketmq.client.producer.TransactionListener later. The class implements two methods for process callback events after the txProducer sends a transactional message.

Note: The annotation is used only on RocketMQ client producer side, it can not be used on consumer side.
