config.properties:

rocketmq.consumerGroup=thConsumerGroup

rocketmq.tags=TAG1
rocketmq.producer.group=thProducerGroup

UserController:

package com.th.controller;

import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

public class MessageListenerImpl implements MessageListenerConcurrently {

	@Override
	public ConsumeConcurrentlyStatus consumeMessage(List<MessageExt> msgs, ConsumeConcurrentlyContext context) {
		for (MessageExt msg : msgs) {
			try {
				System.out.println(">>>>" + new String(msg.getBody(), "UTF-8"));
			} catch (UnsupportedEncodingException e) {
				e.printStackTrace();
				return ConsumeConcurrentlyStatus.RECONSUME_LATER;
			}
		}
		// 如果没有异常会认为都成功消费
		return ConsumeConcurrentlyStatus.CONSUME_SUCCESS;
	}
}

生成者：

浏览器访问地址： http://localhost:8089/rocketMq/test

查看控制台，出现信息消费则成功

悦读

道可道，非常道；名可名，非常名。 无名，天地之始，有名，万物之母。 故常无欲，以观其妙，常有欲，以观其徼。 此两者，同出而异名，同谓之玄，玄之又玄，众妙之门。
