rocketmq集群消费以及广播消费

pom依赖:

        
            org.apache.rocketmq
            rocketmq-client
            4.6.0
            compile
        

生产者：

package com.hscs.cux;

import org.apache.rocketmq.client.producer.DefaultMQProducer;
import org.apache.rocketmq.client.producer.SendResult;
import org.apache.rocketmq.common.message.Message;
import org.apache.rocketmq.remoting.common.RemotingHelper;


/**
 * Created by hand on 2018/5/2.
 */
public class Producer {

    public static void main(String[] args) throws Exception {
        // 创建DefaultMQProducer类并设定生产者名称HSCS_DEV_TST_MSG
        DefaultMQProducer mqProducer = new DefaultMQProducer("hscs_producer-group-test");
        // 设置NameServer地址，如果是集群的话，使用分号;分隔开
        mqProducer.setNamesrvAddr("xxx.xxx.xxx.xxx:9876");
        // 消息最大长度 默认4M
        mqProducer.setMaxMessageSize(4096);
        // 发送消息超时时间，默认3000
        mqProducer.setSendMsgTimeout(3000);
        // 发送消息失败重试次数，默认2
        mqProducer.setRetryTimesWhenSendAsyncFailed(2);
        // 启动消息生产者
        mqProducer.start();

        // 循环十次，发送十条消息
        for (int i = 1; i <= 10; i++) {
            String msg = "hello, 这是第" + i + "条同步消息";
            // 创建消息，并指定Topic(主题)，Tag(标签)和消息内容
            Message message = new Message("HSCS_DEV_TST_MSG", "", msg.getBytes(RemotingHelper.DEFAULT_CHARSET));
            // 发送同步消息到一个Broker，可以通过sendResult返回消息是否成功送达
            SendResult sendResult = mqProducer.send(message);
            System.out.println(sendResult);
        }

        // 如果不再发送消息，关闭Producer实例
        mqProducer.shutdown();
    }
}

消费者：

package com.hscs.cux;

import org.apache.rocketmq.client.consumer.DefaultMQPushConsumer;
import org.apache.rocketmq.client.consumer.listener.ConsumeConcurrentlyContext;
import org.apache.rocketmq.client.consumer.listener.ConsumeConcurrentlyStatus;
import org.apache.rocketmq.client.consumer.listener.MessageListenerConcurrently;
import org.apache.rocketmq.common.consumer.ConsumeFromWhere;
import org.apache.rocketmq.common.message.MessageExt;
import org.apache.rocketmq.common.protocol.heartbeat.MessageModel;
import java.nio.charset.StandardCharsets;
import java.util.List;

public class Consumer {

    public static void main(String[] args) throws Exception {
        // 创建DefaultMQPushConsumer类并设定消费者名称
        DefaultMQPushConsumer mqPushConsumer = new DefaultMQPushConsumer("hscs_consumer-group-test");

        // 设置NameServer地址，如果是集群的话，使用分号;分隔开
        mqPushConsumer.setNamesrvAddr("xxx.xxx.xxx.xxx:9876");

        // 设置Consumer第一次启动是从队列头部开始消费还是队列尾部开始消费
        // 如果不是第一次启动，那么按照上次消费的位置继续消费
        mqPushConsumer.setConsumeFromWhere(ConsumeFromWhere.CONSUME_FROM_FIRST_OFFSET);

        // 设置消费模型，集群还是广播，默认为集群
        //mqPushConsumer.setMessageModel(MessageModel.CLUSTERING);
        mqPushConsumer.setMessageModel(MessageModel.BROADCASTING);
        // 消费者最小线程量
        mqPushConsumer.setConsumeThreadMin(5);

        // 消费者最大线程量
        mqPushConsumer.setConsumeThreadMax(10);

        // 设置一次消费消息的条数，默认是1
        mqPushConsumer.setConsumeMessageBatchMaxSize(1);

        // 订阅一个或者多个Topic，以及Tag来过滤需要消费的消息，如果订阅该主题下的所有tag，则使用*
        mqPushConsumer.subscribe("HSCS_DEV_TST_MSG", "*");

        // 注册回调实现类来处理从broker拉取回来的消息
        mqPushConsumer.registerMessageListener(new MessageListenerConcurrently() {
            // 监听类实现MessageListenerConcurrently接口即可，重写consumeMessage方法接收数据
            @Override
            public ConsumeConcurrentlyStatus consumeMessage(List msgList, ConsumeConcurrentlyContext consumeConcurrentlyContext) {
                MessageExt messageExt = msgList.get(0);
                String body = new String(messageExt.getBody(), StandardCharsets.UTF_8);
                System.out.println("消费者接收到消息: " + messageExt.toString() + "---消息内容为：" + body);
                // 标记该消息已经被成功消费
                return ConsumeConcurrentlyStatus.CONSUME_SUCCESS;
            }
        });

        // 启动消费者实例
        mqPushConsumer.start();
    }
}

spring集成：
application.yml修改：

rocketmq:
  # rocketmq地址
  name-server: 192.168.101.11:9876
  producer:
    # 必须填写 group
    group: test-group
