1. 删除讨厌的告警

在这里插入图片描述
如上sh: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)和OpenJDK 64-Bit Server VM warning: ignoring option PermSize=128m; support was removed in 8.0两个异常太烦人了。

  1. 删除sh: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)
    • 执行localedef -f UTF-8 -i en_US en_US.UTF-8
  2. 删除OpenJDK 64-Bit Server VM warning: ignoring option PermSize=128m; support was removed in 8.0
    • 修改tools.sh脚本，删除-XX:PermSize=128m -XX:MaxPermSize=128m

2. 生产者和消费者代码

2.1 生产者代码

package com.tom.lrocket;
import org.apache.rocketmq.client.producer.DefaultMQProducer;
import org.apache.rocketmq.client.producer.SendResult;
import org.apache.rocketmq.common.message.Message;

public class Producer1 {
    
    
    public static void main(String[] args) throws Exception {
    
    
        // 实例化消息生产者Producer
        DefaultMQProducer producer = new DefaultMQProducer("demo-producer-group");
        // 设置NameServer的地址
        producer.setNamesrvAddr("localhost:9876");
        // 启动Producer实例
        producer.start();
        int count = 1000;
        for (int i = 0; i < count; i++) {
    
    
            String topic = "TOPIC-1";
            // 创建消息，并指定Topic，Tag和消息体
            Message msg = new Message(topic, "TagB", (topic + " Hello RocketMQ " + i).getBytes());
            // 发送消息到一个Broker
            SendResult send = producer.send(msg);
            System.out.println(send);
            Thread.sleep(1000);

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

2.2 消费者代码

package com.tom.lrocket;

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.message.MessageExt;

import java.util.List;

public class Consumer1 {
    
    
    public static void main(String[] args) throws Exception {
    
    
        // 实例化消费者
        DefaultMQPushConsumer consumer = new DefaultMQPushConsumer("lixi");
        // 设置NameServer的地址
        consumer.setNamesrvAddr("localhost:9876");
        // 订阅一个或者多个Topic，以及Tag来过滤需要消费的消息
        String topic = "TOPIC-1";
        consumer.subscribe(topic, "TagB");
        // 注册回调实现类来处理从broker拉取回来的消息
        consumer.registerMessageListener(new MessageListenerConcurrently() {
    
    
            @Override
            public ConsumeConcurrentlyStatus consumeMessage(List<MessageExt> msgs, ConsumeConcurrentlyContext context) {
    
    
                System.out.printf("%s Receive New Messages: %s %n", Thread.currentThread().getName(), msgs);
                // 标记该消息已经被成功消费
                return ConsumeConcurrentlyStatus.CONSUME_SUCCESS;
            }
        });
        // 启动消费者实例
        consumer.start();
        System.out.printf("Consumer Started.%n");
    }
}

2.3 解释Message Key 、Unique Key、Message Id 的区别

from：https://cloud.tencent.com/developer/article/1581366
github的解释
在这里插入图片描述

RocketMQ提供了3种消息查询方式：

  • 按照Message Key 查询：消息的key是业务开发同学在发送消息之前自行指定的，通常会把具有业务含义，区分度高的字段作为消息的key，如用户id，订单id等。
  • 按照Unique Key查询：除了业务开发同学明确的指定消息中的key，RocketMQ生产者客户端在发送发送消息之前，会自动生成一个UNIQ_KEY，设置到消息的属性中，从逻辑上唯一代表一条消息。
  • 按照Message Id 查询：Message Id 是消息发送后，在Broker端生成的，其包含了Broker的地址，和在CommitLog中的偏移信息，并会将Message Id作为发送结果的一部分进行返回。Message Id中属于精确匹配，从物理上唯一代表一条消息，查询效率更高。
  • 温馨提示：如果消息消费失败需要重试，RocketMQ 的做法是将消息重新发送到 Broker 服务器，此时全局 msgId 是不会发送变化的，但该消息的 offsetMsgId 会发送变 化，因为其存储在服务器中的位置发生了变化。

从发送端可以看到msgId=AC1086D51C6E18B4AAC2948F16B10000, offsetMsgId=AC1086D500002A9F00000000000639BC。msgId是Unique Key，offsetMsgId是Message Id 。

SendResult [sendStatus=SEND_OK, msgId=AC1086D51C6E18B4AAC2948F16B10000, offsetMsgId=AC1086D500002A9F00000000000639BC, messageQueue=MessageQueue [topic=TOPIC-1, brokerName=broker-a, queueId=2], queueOffset=284]

从接受的消息可以看到msgId=AC1086D500002A9F00000000000639BC和UNIQ_KEY=AC1086D51C6E18B4AAC2948F16B10000。

ConsumeMessageThread_lixi_2 Receive New Messages: [MessageExt [brokerName=broker-a, queueId=2, storeSize=184, queueOffset=284, sysFlag=0, bornTimestamp=1722255605426, bornHost=/172.18.0.1:60040, storeTimestamp=1722255605436, storeHost=/172.16.134.213:10911, msgId=AC1086D500002A9F00000000000639BC, commitLogOffset=407996, bodyCRC=1008200206, reconsumeTimes=0, preparedTransactionOffset=0, toString()=Message{
    
    topic='TOPIC-1', flag=0, properties={
    
    CONSUME_START_TIME=1722255633739, UNIQ_KEY=AC1086D51C6E18B4AAC2948F16B10000, MIN_OFFSET=0, TAGS=TagB, WAIT=true, MAX_OFFSET=290}, body=[84, 79, 80, 73, 67, 45, 49, 32, 72, 101, 108, 108, 111, 32, 82, 111, 99, 107, 101, 116, 77, 81, 32, 48], transactionId='null'}]]
