Currently, I found a workaround to get batch messages. But we still perfer
batch listener
```@RocketMQMessageListener(topic = "demo_product", consumerGroup =
"demo_batch_product_consumerGroup", consumeMode = ConsumeMode.ORDERLY)
public class ProductBatchConsumer implements RocketMQListener<String>,
RocketMQPushConsumerLifecycleListener {
private final Logger logger = LoggerFactory.getLogger(this.getClass());
@Override
public void onMessage(String message) {
// do noting, have to implement RocketMQListener or throw error
}
private AtomicInteger atomicInteger = new AtomicInteger();
@Override
public void prepareStart(DefaultMQPushConsumer consumer) {
consumer.setPullInterval(1000);
consumer.setConsumeThreadMin(1);
consumer.setConsumeThreadMax(1);
consumer.setConsumeMessageBatchMaxSize(1000);
consumer.setPullBatchSize(100);
consumer.registerMessageListener((MessageListenerConcurrently)
(msgs, context) -> {
System.out.println("batchSize: " + msgs.size());
int result = atomicInteger.addAndGet(msgs.size());
System.out.println("totalSize: " + result);
return ConsumeConcurrentlyStatus.CONSUME_SUCCESS;
});
}
}```
