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
org.apache.rocketmq
rocketmq-spring-boot-starter
2.0.4
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-groupSpringBoot 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 {
@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 {
@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 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 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 {
@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 {
@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 {
@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

@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);
