Springboot rockemq整合配置 发布订阅 广播

一.预备环境
1.系统
Windows
2. 环境
JDK1.8、Maven、Git

二. RocketMQ部署
1.下载
1.1地址：http://rocketmq.apache.org/release_notes/release-notes-4.7.1/
1.2 安装
1.3 在桌面上，右键单击“计算机”图标。从上下文菜单中选择“属性”。单击高级系统设置链接。单击环境变量。然后添加或更改环境变量。

ROCKETMQ_HOME="D:\rocketmq"
NAMESRV_ADDR="localhost:9876"

三 启动RocketMQ
3.1Cmd命令框执行进入至‘MQ文件夹\bin’下，然后执行‘start mqnamesrv.cmd

这样表示启动成功
3.2修改broker.conf配置

brokerIP1=localhost#服务器的公网IP地址
namesrvAddr =localhost:9876

启动 mqbroker

start mqbroker -c ../conf/broker.conf autoCreateTopicEnable=true

启动成功页面

如果启动失败，一般是内存配置够大修改runbroker.cmd配置，删除C:\Users\Administrator\store的文件，记住这个文件记得删除

set "JAVA_OPT=%JAVA_OPT% -server -Xms256m -Xmx256m -Xmn125m"
set "JAVA_OPT=%JAVA_OPT% -XX:+UseG1GC -XX:G1HeapRegionSize=16m -XX:G1ReservePercent=25 -XX:InitiatingHeapOccupancyPercent=30 -XX:SoftRefLRUPolicyMSPerMB=0 -XX:SurvivorRatio=8"
set "JAVA_OPT=%JAVA_OPT% -verbose:gc -Xloggc:%USERPROFILE%\mq_gc.log -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintGCApplicationStoppedTime -XX:+PrintAdaptiveSizePolicy"
set "JAVA_OPT=%JAVA_OPT% -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=5 -XX:GCLogFileSize=30m"
set "JAVA_OPT=%JAVA_OPT% -XX:-OmitStackTraceInFastThrow"
set "JAVA_OPT=%JAVA_OPT% -XX:+AlwaysPreTouch"
set "JAVA_OPT=%JAVA_OPT% -XX:MaxDirectMemorySize=15g"
set "JAVA_OPT=%JAVA_OPT% -XX:-UseLargePages -XX:-UseBiasedLocking"
set "JAVA_OPT=%JAVA_OPT% -Djava.ext.dirs=%BASE_DIR%lib"
set "JAVA_OPT=%JAVA_OPT% -cp %CLASSPATH%"
"%JAVA%" %JAVA_OPT% %*

四 引入jar包
4.1版本要跟客户端安装的版本一致

	
			org.apache.rocketmq
			rocketmq-client
			4.7.1
		

4.2 发布订阅
4.2.1创建发布

public class OrderedProducer {
    public static void main(String[] args) throws Exception {
        //Instantiate with a producer group name.
        MQProducer producer = new DefaultMQProducer("example_group_name");
        //Launch the instance.
        producer.start();
        String[] tags = new String[] {"TagA", "TagB", "TagC", "TagD", "TagE"};
        for (int i = 0; i < 100; i++) {
            int orderId = i % 10;
            //Create a message instance, specifying topic, tag and message body.
            Message msg = new Message("TopicTestjjj", tags[i % tags.length], "KEY" + i,
                    ("Hello RocketMQ " + i).getBytes(RemotingHelper.DEFAULT_CHARSET));
            SendResult sendResult = producer.send(msg, new MessageQueueSelector() {
            @Override
            public MessageQueue select(List mqs, Message msg, Object arg) {
                Integer id = (Integer) arg;
                int index = id % mqs.size();
                return mqs.get(index);
            }
            }, orderId);

            System.out.printf("%s%n", sendResult);
        }
        //server shutdown
        producer.shutdown();
    }
}

4.2.2 创建订阅

public class OrderedConsumer {
    public static void main(String[] args) throws Exception {
        DefaultMQPushConsumer consumer = new DefaultMQPushConsumer("example_group_name");

        consumer.setConsumeFromWhere(ConsumeFromWhere.CONSUME_FROM_FIRST_OFFSET);

        consumer.subscribe("TopicTest", "TagA || TagC || TagD");

        consumer.registerMessageListener(new MessageListenerOrderly() {

            AtomicLong consumeTimes = new AtomicLong(0);
            @Override
            public ConsumeOrderlyStatus consumeMessage(List msgs,
                                                       ConsumeOrderlyContext context) {
                context.setAutoCommit(false);
                System.out.printf(Thread.currentThread().getName() + " Receive New Messages: " + msgs + "%n");
                this.consumeTimes.incrementAndGet();
                if ((this.consumeTimes.get() % 2) == 0) {
                    return ConsumeOrderlyStatus.SUCCESS;
                } else if ((this.consumeTimes.get() % 3) == 0) {
                    return ConsumeOrderlyStatus.ROLLBACK;
                } else if ((this.consumeTimes.get() % 4) == 0) {
                    return ConsumeOrderlyStatus.COMMIT;
                } else if ((this.consumeTimes.get() % 5) == 0) {
                    context.setSuspendCurrentQueueTimeMillis(3000);
                    return ConsumeOrderlyStatus.SUSPEND_CURRENT_QUEUE_A_MOMENT;
                }
                return ConsumeOrderlyStatus.SUCCESS;

            }
        });

        consumer.start();

        System.out.printf("Consumer Started.%n");
    }
}

4.3广播
4.3.1创建广播生产者

public class BroadcastProducer {
    public static void main(String[] args) throws Exception {
        DefaultMQProducer producer = new DefaultMQProducer("ProducerGroupName");
        producer.start();

        for (int i = 0; i < 100; i++){
            Message msg = new Message("TopicTest",
                "TagA",
                "OrderID188",
                "Hello world".getBytes(RemotingHelper.DEFAULT_CHARSET));
            SendResult sendResult = producer.send(msg);
            System.out.printf("%s%n", sendResult);
        }
        producer.shutdown();
    }
}

4.3.2创建广播消费者

public class BroadcastConsumer {
    public static void main(String[] args) throws Exception {
        DefaultMQPushConsumer consumer = new DefaultMQPushConsumer("example_group_name");

        consumer.setConsumeFromWhere(ConsumeFromWhere.CONSUME_FROM_FIRST_OFFSET);

        //set to broadcast mode
        consumer.setMessageModel(MessageModel.BROADCASTING);

        consumer.subscribe("TopicTest", "TagA || TagC || TagD");

        consumer.registerMessageListener(new MessageListenerConcurrently() {

            @Override
            public ConsumeConcurrentlyStatus consumeMessage(List msgs,
                ConsumeConcurrentlyContext context) {
                System.out.printf(Thread.currentThread().getName() + " Receive New Messages: " + msgs + "%n");
                return ConsumeConcurrentlyStatus.CONSUME_SUCCESS;
            }
        });

        consumer.start();
        System.out.printf("Broadcast Consumer Started.%n");
    }
}
