RocketMQ 快速开始quickstart && borker配置文件

producer

public class Producer1 {

    public static void main(String[] agrs) throws MQClientException, UnsupportedEncodingException, RemotingException, InterruptedException, MQBrokerException {

        DefaultMQProducer producer = new
                DefaultMQProducer("TopicTest3-produceGroup1",ACLClient.getAclRPCHook());
        // Specify name server addresses.
        producer.setNamesrvAddr("10.1.54.46:9876");
        producer.setInstanceName("producer 1");
        //Launch the instance.
        producer.start();
        
        for (int i = 0; i < 10; i++) {
            //Create a message instance, specifying topic, tag and message body.
            Message msg = new Message("TopicTest3" /* Topic */,
                    "abc" /* Tag */,"OrderID188",
                    ("Hello RocketMQ " +
                            i).getBytes(RemotingHelper.DEFAULT_CHARSET) /* Message body */
            );
            msg.putUserProperty("coal", String.valueOf(i));
            //Call send message to deliver message to one of brokers.
            SendResult sendResult = producer.send(msg);
            System.out.printf("%s%n", sendResult);
        }
        //Shut down once the producer instance is not longer in use.
        producer.shutdown();

    }
}

consumer

public class AclConsumer {

    public static void main(String[] agrs) throws MQClientException {
        //指定Group和ACL
        DefaultMQPushConsumer consumer = new DefaultMQPushConsumer("consumerGroup5", ACLClient.getAclRPCHook(), new AllocateMessageQueueAveragely());

        consumer.setNamesrvAddr("localhost:9876");
        consumer.setInstanceName("consumer 5");

        //集群订阅(MessageModel.CLUSTERING)
        //广播订阅(MessageModel.BROADCASTING)
        consumer.setMessageModel(MessageModel.BROADCASTING);

        //CONSUME_FROM_LAST_OFFSET 默认策略，从该队列最尾开始消费，即跳过历史消息
        //CONSUME_FROM_FIRST_OFFSET 从队列最开始开始消费，即历史消息（还储存在broker的）全部消费一遍
        //CONSUME_FROM_TIMESTAMP 从某个时间点开始消费，和setConsumeTimestamp()配合使用，默认是半个小时以前
        consumer.setConsumeFromWhere(ConsumeFromWhere.CONSUME_FROM_FIRST_OFFSET);

        //可以修改每次消费消息的数量，默认设置是每次消费一条
        consumer.setConsumeMessageBatchMaxSize(10);


        //设置consumer所订阅的Topic和Tag，*代表全部的Tag MessageSelector.byTag
        consumer.subscribe("TopicTest3", MessageSelector.bySql("coal between 2 and 7"));

        //注册消费的监听
        consumer.registerMessageListener(MessageListener.getInstance());

        consumer.start();
        System.out.println("consumer 2 is started");

    }
}

ACLClient

public class ACLClient {

    private static final String ACL_ACCESS_KEY = "RocketMQ2";
    private static final String ACL_SECRET_KEY = "12345678";

    static RPCHook getAclRPCHook() {
        return new AclClientRPCHook(new SessionCredentials(ACL_ACCESS_KEY,ACL_SECRET_KEY));
    }

    private static final String TEST_ACL_ACCESS_KEY = "testKey";
    private static final String TEST_ACL_SECRET_KEY = "12345678";

    static RPCHook getTestAclRPCHook() {
        return new AclClientRPCHook(new SessionCredentials(TEST_ACL_ACCESS_KEY,TEST_ACL_SECRET_KEY));
    }


    private static final String ERROR_ACL_ACCESS_KEY = "RocketMQ333";
    private static final String ERROR_ACL_SECRET_KEY = "12345673333";

    static RPCHook getErrorAclRPCHook() {
        return new AclClientRPCHook(new SessionCredentials(ERROR_ACL_ACCESS_KEY,ERROR_ACL_SECRET_KEY));
    }
}

Consumer 的 MessageListener

public class MessageListener implements MessageListenerConcurrently {

    private static MessageListener instance = null;

    public static MessageListener getInstance() {
        if (instance == null) {
            synchronized (MessageListener.class) {
                if (instance == null) {
                    instance = new MessageListener();
                }
            }
        }
        return instance;
    }

    @Override
    public ConsumeConcurrentlyStatus consumeMessage(List msgs, ConsumeConcurrentlyContext consumeConcurrentlyContext) {
        for (MessageExt messageExt : msgs) {
            String messageBody = new String(messageExt.getBody());
            System.out.println(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(
                    new Date()) + "消费响应： msgBody : " + messageBody);//输出消息内容
        }
        //ACK
        //CONSUME_SUCCESS 消费成功
        //RECONSUME_LATER 消费失败，需要稍后重新消费
        return ConsumeConcurrentlyStatus.CONSUME_SUCCESS;
    }

    private MessageListener() {
    }
}
