增加selector选择器，根据key选择进入的Broker队列
producer.send(msgToBroker, new MessageQueueSelector() {
                @Override
                public MessageQueue select(List<MessageQueue> mqs, Message msgToBroker, Object arg) {
                    // 根据key来选择队列
                    Integer id = (Integer) arg;
                    int index = id % mqs.size();
                    for (MessageQueue mq : mqs) {
                        System.out.println("current queue: " + mq.getQueueId());
                    }
                    System.out.println("select id: " + index);
                    return mqs.get(index);
                }
            }, key, new SendCallback() {
                public void onSuccess(SendResult sendResult) {
                    System.out.println(message);
                }

                public void onException(Throwable throwable) {
                    throwable.printStackTrace();
                }
            });
编译后启动服务端和客户端
进入target目录
启动生产者生产数据：java -Drocketmq.namesrv.addr=127.0.0.1:9876 -cp preliminary.demo-1.0-SNAPSHOT.jar com.alibaba.middleware.race.rocketmq.Producer
启动消费者消费数据：java -Drocketmq.namesrv.addr=127.0.0.1:9876 -cp preliminary.demo-1.0-SNAPSHOT.jar com.alibaba.middleware.race.rocketmq.Consumer

启动&参数修改

mqnamesrv   启动NameServer  jps - NamesrvStartup
mqbroker -n localhost:9876 启动broker jps - BrokerStartup 默认端口10911
mqadmin updateBrokerConfig -c DefaultCluster -n 127.0.0.1:9876 -k listenPort -v 10911 更新broker参数配置

查看当前系统状态

mqadmin clusterList -n 127.0.0.1:9876

查看当前所有topicList/创建

mqadmin topicList -n 127.0.0.1:9876
mqadmin updateTopic -n 127.0.0.1:9876 -c DefaultCluster -t topic名称

查看broker状态

mqadmin brokerStatus -n 127.0.0.1:9876 -b 127.0.0.1:10911

 查看某个topic的状态

mqadmin topicStatus -n 127.0.0.1:9876 -t TOPIC-IT-WORKER-TEST
当前可见，producer只发送了一条消息，Max offset为1，最后收到消息的时间是last updated，由于配置四个broker都是本机，只有第一个收到了当前第一条消息
第二张图为发了四条消息之后的状态，看起来可能就是轮询的，因为当我增加4条key为1的msg之后，仍然是四个节点每个两条

查看连接的procedure/consumer

mqadmin producerConnection -n 127.0.0.1:9876 -g procedure_group_name -t TOPIC-IT-WORKER-TEST
mqadmin consumerConnection -n 127.0.0.1:9876 -g consumer_group_name

查看某个key对应的msg

mqadmin queryMsgByKey -n 127.0.0.1:9876 -t TOPIC-IT-WORKER-TEST-1 -k 1
因为之前发送了5条key为1的数据，所以这里可以看到是5条，每条都有一个MESSAGE ID

根据ID查看对应的MSG

mqadmin queryMsgById  -g consumer_group_name -i AC1F78B700002A9F00000000000A3208  -n 127.0.0.1:9876

根据位置偏移查询上面的那条数据

 mqadmin queryMsgByOffset -n  127.0.0.1:9876 -o 1 -t TOPIC-IT-WORKER-TEST-1 -i 1 -b izm5e210z0uiwyavdbmpxaz

查看消费详情

mqadmin consumerProgress -n 127.0.0.1:9876 -g consumer_group_name
这里消费了一条，一共八条，差7条没有消费

重置消费端offset

mqadmin resetOffsetByTime  -n 127.0.0.1:9876 -g consumer_group_name -t TOPIC-IT-WORKER-TEST-1 -f true -s 1536820000

打印broker中某个队列里的消息

mqadmin printMsgByQueue -a izm5e210z0uiwyavdbmpxaz -t T1 -n 127.0.0.1:9876 -i 1 -p true -d true
这里可以看出，storeSize最后多了一条原因就是最后的body里12是两位，废话。。。

直接打印消息

mqadmin printMsg -t TOPIC-IT-WORKER-TEST-1 -n 127.0.0.1:9876
