SpringBoot集成RocketMQ的使用示例

作者：小月亮与六便士

RocketMQ是阿里巴巴开源的一款消息中间件,性能优秀,功能齐全,被广泛应用在各种业务场景,本文就来介绍一下SpringBoot集成RocketMQ的使用示例,感兴趣的可以了解一下

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: 192.168.152.165:9876
  producer:
    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 {


    @Autowired
    private RocketMQTemplate rocketMQTemplate;

    //同步消息
    @Test
    public 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
    @Test
    public void sendASYCMsg() throws InterruptedException {
        Message message = MessageBuilder.withPayload("boot发送异步消息").build();
        rocketMQTemplate.asyncSend("helloTopicBoot", message, new SendCallback() {
            @Override
            public void onSuccess(SendResult sendResult) {
                System.out.println("发送状态:"+sendResult.getSendStatus());
            }

            @Override
            public void onException(Throwable throwable) {
                System.out.println("消息发送失败");
            }
        });
        TimeUnit.SECONDS.sleep(5);
    }

    //一次性消息
    @Test
    public 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> {

    @Override
    public 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> {

    @Override
    public 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
    @Test
    public void sendOrderlyMsg(){
        //设置队列选择器
        rocketMQTemplate.setMessageQueueSelector(new MessageQueueSelector() {
            @Override
            public 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> {

    @Override
    public 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
    @Test
    public 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> {

    @Override
    public 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
    @Test
    public 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> {

    @Override
    public 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
    @Test
    public 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> {

    @Override
    public void onMessage(MessageExt messageExt) {
        System.out.println("success get:发送时间"+new Date()+new String(messageExt.getBody(), Charset.defaultCharset()));
    }
}
