SpringBoot整合RocketMQ发送并接收消费者返回一个String报错：CODE: 10006 DESC: send request message to ＜TestTopic＞ OK,

运行时报错展示：

Received Message : 同步消息，返回string

问题代码：
1.生产者

@RequestMapping("/testReceiveStr")
public String testReceiveStr(){
	String receive = rocketMQTemplate.sendAndReceive(topic, "同步消息，返回string",
                                                        String.class);
    System.out.printf("同步消息-返回一个String类型的结果：%s%n",receive);
    return "success";
}

2.消费者

@Component
@RocketMQMessageListener(consumerGroup = "MyConsumerGroup", topic = "TestTopic",
        consumeMode = ConsumeMode.CONCURRENTLY)
public class Consumer implements RocketMQListener {
    @Override
    public void onMessage(String message) {
        System.out.println("Received Message : "+message);
    }
}

问题分析：
消费者那边收到了消息，报这个错是因为消费者没有进行回执，导致生产者那边等待消息超时报错。所以在要求消费者有回执消息的场景下，消费者一定要选择正确。
消费者继承的接口中选择RocketMQReplyListener，进行实现。

问题处理：

@Component
@RocketMQMessageListener(consumerGroup = "MyConsumerGroup", topic = "TestTopic",
        consumeMode = ConsumeMode.CONCURRENTLY)
public class Consumer implements RocketMQReplyListener {

    @Override
    public Object onMessage(Object message) {
        System.out.println("Received Message : "+message);
        return message;
    }
}
