SpringBoot 集成 RocketMQ

一、RocketMQ基本概念

消息模型（Message Model）

RocketMQ主要由Producer、Broker、Consumer三部分组成，其中Producer负责生产消息，Consumer负责消费消息，Broker负责存储消息。Broker在实际部署过程中对应一台服务器，每个Broker可以存储多个Topic的消息，每个Topic的消息也可以分片存储于不同的Broker。MessageQueue用于存储消息的物理地址，每个Topic中的消息地址存储于多个MessageQueue中。ConsumerGroup由多个Consumer实例构成。

1、在springBoot项目中添加Maven依赖

        <dependency><groupId>org.apache.rocketmq</groupId><artifactId>rocketmq-spring-boot-starter</artifactId><version>2.0.4</version></dependency>

2、添加配置：

application.yml 文件中添加如下配置：

rocketmq:name-server: 192.168.152.165:9876producer:group: my-group

SpringBoot 集成 RocketMQ代码：

生产者：消息发送的三种方式

package com.rocketmq.springbootrocketmq;import org.apache.rocketmq.client.producer.SendCallback;
import org.apache.rocketmq.client.producer.SendResult;
import org.apache.rocketmq.spring.core.RocketMQTemplate;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.messaging.Message;
import org.springframework.messaging.support.MessageBuilder;
import org.springframework.test.context.junit4.SpringRunner;import java.util.concurrent.TimeUnit;@RunWith(SpringRunner.class)
@SpringBootTest
public class T {@Autowiredprivate RocketMQTemplate rocketMQTemplate;//同步消息@Testpublic void testRocketMQ() {Message msg = MessageBuilder.withPayload("boot发送同步消息").build();rocketMQTemplate.send("helloTopicBoot", msg);System.out.println("success send");}//异步消息@Testpublic void sendASYCMsg() throws InterruptedException {Message message = MessageBuilder.withPayload("boot发送异步消息").build();rocketMQTemplate.asyncSend("helloTopicBoot", message, new SendCallback() {@Overridepublic void onSuccess(SendResult sendResult) {System.out.println("发送状态:"+sendResult.getSendStatus());}@Overridepublic void onException(Throwable throwable) {System.out.println("消息发送失败");}});TimeUnit.SECONDS.sleep(5);}//一次性消息@Testpublic void sendOneWayRocketMQ() {Message msg = MessageBuilder.withPayload("boot发送一次性消息").build();rocketMQTemplate.sendOneWay("helloTopicBoot", msg);}}

消费者：

package com.example.springbooTRocketMQConsumer.listener;import org.apache.rocketmq.common.message.MessageExt;
import org.apache.rocketmq.spring.annotation.RocketMQMessageListener;
import org.apache.rocketmq.spring.core.RocketMQListener;
import org.springframework.stereotype.Component;import java.nio.charset.Charset;@Component
@RocketMQMessageListener(consumerGroup = "htbConsumerGroup",topic = "helloTopicBoot")
public class HelloTopicListener implements RocketMQListener<MessageExt> {@Overridepublic void onMessage(MessageExt messageExt) {System.out.println("success get:"+new String(messageExt.getBody(), Charset.defaultCharset()));}
}

消息消费的两种模式

集群模式：默认模式

广播模式：

消费者：messageModel = MessageModel.BROADCASTING

package com.example.springbooTRocketMQConsumer.listener;import org.apache.rocketmq.common.message.MessageExt;
import org.apache.rocketmq.spring.annotation.MessageModel;
import org.apache.rocketmq.spring.annotation.RocketMQMessageListener;
import org.apache.rocketmq.spring.core.RocketMQListener;
import org.springframework.stereotype.Component;import java.nio.charset.Charset;@Component
@RocketMQMessageListener(consumerGroup = "htbConsumerGroup",topic = "helloTopicBoot",messageModel = MessageModel.BROADCASTING)
public class HelloTopicListener implements RocketMQListener<MessageExt> {@Overridepublic void onMessage(MessageExt messageExt) {System.out.println("success get:"+new String(messageExt.getBody(), Charset.defaultCharset()));}
}

顺序消息

生产者：

    //顺序消息@Testpublic void sendOrderlyMsg(){//设置队列选择器rocketMQTemplate.setMessageQueueSelector(new MessageQueueSelector() {@Overridepublic MessageQueue select(List<MessageQueue> list, org.apache.rocketmq.common.message.Message message, Object o) {String orderIdStr = (String) o;long orderId = Long.parseLong(orderIdStr);int index = (int)orderId % list.size();return list.get(index);}});List<OrderStep> orderSteps = OrderUtil.buildOrders();for (OrderStep orderStep : orderSteps) {Message msg = MessageBuilder.withPayload(orderStep.toString()).build();rocketMQTemplate.sendOneWayOrderly("orderlyTopicBoot",msg,String.valueOf(orderStep.getOrderId()));}}

消费者：

package com.example.springbooTRocketMQConsumer.listener;import org.apache.rocketmq.common.message.MessageExt;
import org.apache.rocketmq.spring.annotation.ConsumeMode;
import org.apache.rocketmq.spring.annotation.RocketMQMessageListener;
import org.apache.rocketmq.spring.core.RocketMQListener;
import org.springframework.stereotype.Component;import java.nio.charset.Charset;@Component
@RocketMQMessageListener(consumerGroup = "orderlyConsumerBoot",topic = "orderlyTopicBoot",consumeMode = ConsumeMode.ORDERLY)
public class OrderlyTopicListener implements RocketMQListener<MessageExt> {@Overridepublic void onMessage(MessageExt messageExt) {System.out.println("当前线程:" + Thread.currentThread() + "队列ID"+messageExt.getQueueId() + ",消息内容:" + new String(messageExt.getBody(),Charset.defaultCharset()));}
}

延迟消息

生产者：

    //延迟消息@Testpublic void sendDelayRocketMQ() {Message msg = MessageBuilder.withPayload("boot发送延时消息，发送时间:"+new Date()).build();rocketMQTemplate.syncSend("helloTopicBoot", msg,3000,3);}

消费者：

package com.example.springbooTRocketMQConsumer.listener;import org.apache.rocketmq.common.message.MessageExt;
import org.apache.rocketmq.spring.annotation.MessageModel;
import org.apache.rocketmq.spring.annotation.RocketMQMessageListener;
import org.apache.rocketmq.spring.core.RocketMQListener;
import org.springframework.stereotype.Component;import java.nio.charset.Charset;
import java.util.Date;@Component
@RocketMQMessageListener(consumerGroup = "htbConsumerGroup",topic = "helloTopicBoot")
public class DelayTopicListener implements RocketMQListener<MessageExt> {@Overridepublic void onMessage(MessageExt messageExt) {System.out.println("success get:发送时间"+new Date()+new String(messageExt.getBody(), Charset.defaultCharset()));}
}

消息Tag条件过滤

生成者

    //Tag消息@Testpublic void sendTagFilterRocketMQ() {Message msg1 = MessageBuilder.withPayload("消息A").build();rocketMQTemplate.sendOneWay("tagFilterBoot:TagA", msg1);Message msg2 = MessageBuilder.withPayload("消息B").build();rocketMQTemplate.sendOneWay("tagFilterBoot:TagB", msg2);Message msg3 = MessageBuilder.withPayload("消息C").build();rocketMQTemplate.sendOneWay("tagFilterBoot:TagC", msg3);}

消费者：

package com.example.springbooTRocketMQConsumer.listener;import org.apache.rocketmq.common.message.MessageExt;
import org.apache.rocketmq.spring.annotation.MessageModel;
import org.apache.rocketmq.spring.annotation.RocketMQMessageListener;
import org.apache.rocketmq.spring.core.RocketMQListener;
import org.springframework.stereotype.Component;import java.nio.charset.Charset;
import java.util.Date;@Component
@RocketMQMessageListener(consumerGroup = "tagFilterGroupBoot",topic = "tagFilterBoot",selectorExpression = "TagA || TagC")
public class TagFilterTopicListener implements RocketMQListener<MessageExt> {@Overridepublic void onMessage(MessageExt messageExt) {System.out.println("success get:发送时间"+new Date()+new String(messageExt.getBody(), Charset.defaultCharset()));}
}

SQL92消息过滤

生产者：

    //SQL92消息@Testpublic void sendSQL92FilterRocketMQ() {Message msg1 = MessageBuilder.withPayload("小红,年龄22,体重45").setHeader("age","22").setHeader("weight",45).build();rocketMQTemplate.sendOneWay("SQL92FilterBoot", msg1);Message msg2 = MessageBuilder.withPayload("小明,年龄25,体重60").setHeader("age","25").setHeader("weight",60).build();rocketMQTemplate.sendOneWay("SQL92FilterBoot", msg2);Message msg3 = MessageBuilder.withPayload("小蓝,年龄40,体重70").setHeader("age","40").setHeader("weight",70).build();rocketMQTemplate.sendOneWay("SQL92FilterBoot", msg3);}

消费者：

package com.example.springbooTRocketMQConsumer.listener;import org.apache.rocketmq.common.message.MessageExt;
import org.apache.rocketmq.spring.annotation.RocketMQMessageListener;
import org.apache.rocketmq.spring.annotation.SelectorType;
import org.apache.rocketmq.spring.core.RocketMQListener;
import org.springframework.stereotype.Component;import java.nio.charset.Charset;
import java.util.Date;@Component
@RocketMQMessageListener(consumerGroup = "SQL92FilterGroupBoot",topic = "SQL92FilterBoot",selectorType = SelectorType.SQL92,selectorExpression = "age > 23 and weight > 60")
public class SQL92FilterTopicListener implements RocketMQListener<MessageExt> {@Overridepublic void onMessage(MessageExt messageExt) {System.out.println("success get:发送时间"+new Date()+new String(messageExt.getBody(), Charset.defaultCharset()));}
}
