SpringBoot整合RocketMQ

简单记录一下SpringBoot整合RocketMQ

pom.xml

        <dependency>
            <groupId>org.apache.rocketmq</groupId>
            <artifactId>rocketmq-common</artifactId>
            <version>4.6.1</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/org.apache.rocketmq/rocketmq-client -->
        <dependency>

        </dependency>

Producer配置

Config配置类

用于在系统启动时初始化producer参数并启动

​
import org.apache.rocketmq.client.exception.MQClientException;
import org.apache.rocketmq.client.producer.DefaultMQProducer;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
​
@Configuration
public class MQConfig {
    public static final Logger LOGGER = LoggerFactory.getLogger(MQConfig.class);
​
    @Value("${rocketmq.producer.groupName}")
    private String groupName;
​
    @Value("${rocketmq.producer.namesrvAddr}")
    private String namesrvAddr;
​
    @Bean
    public DefaultMQProducer getRocketMQProducer() {
​
        DefaultMQProducer producer;
        producer = new DefaultMQProducer(this.groupName);
​
        producer.setNamesrvAddr(this.namesrvAddr);
​
        try {
            producer.start();
            System.out.println("start....");
​
            LOGGER.info(String.format("producer is start ! groupName:[%s],namesrvAddr:[%s]", this.groupName,
                    this.namesrvAddr));
        } catch (MQClientException e) {
            LOGGER.error(String.format("producer is error {}", e.getMessage(), e));
        }
        return producer;
​
    }
}
​

Service消息发送类

​
import org.apache.rocketmq.client.producer.DefaultMQProducer;
import org.apache.rocketmq.common.message.Message;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service
public class MQService {
    @Autowired
    DefaultMQProducer producer;
    
    
    public Object sendMsg(String string) {
        
        for (int i = 0; i < 1; i++) {
            Message message = new Message("tpk02", "xx".getBytes());
            
            try {
                return producer.send(message);
            } catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } 
        }
        return null;
    }
}
​

配置文件

spring.application.name=mq01
rocketmq.producer.namesrvAddr=192.168.150.131:9876
rocketmq.producer.groupName=${spring.application.name}
server.port=8081

Consumer配置

Config配置类

import org.apache.rocketmq.client.consumer.DefaultMQPushConsumer;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
​
@Configuration
public class MQConfig {
    
    
    public static final Logger logger = LoggerFactory.getLogger(MQConfig.class);
    
    @Value("${rocketmq.consumer.namesrvAddr}")
    private String namesrvAddr;
    @Value("${rocketmq.consumer.groupName}")
    private String groupName;
    @Value("${rocketmq.consumer.topics}")
    private String topics;
    
    @Bean
    public DefaultMQPushConsumer getRocketMQConsumer() throws Exception {
        
        DefaultMQPushConsumer consumer = new DefaultMQPushConsumer(groupName);
        consumer.setNamesrvAddr(namesrvAddr);
        consumer.subscribe(topics, "*");
        
        consumer.registerMessageListener(new MyMessageListener() );
        consumer.start();
        
        return consumer;
    }
}
​

消息处理类

​
import java.util.List;
​
import org.apache.rocketmq.client.consumer.listener.ConsumeConcurrentlyContext;
import org.apache.rocketmq.client.consumer.listener.ConsumeConcurrentlyStatus;
import org.apache.rocketmq.client.consumer.listener.MessageListenerConcurrently;
import org.apache.rocketmq.common.message.MessageExt;
​
public class MyMessageListener implements MessageListenerConcurrently {
        @Override
        public ConsumeConcurrentlyStatus consumeMessage(List<MessageExt> msgs, ConsumeConcurrentlyContext context) {
            System.out.println("来啦！！22！");
            for (MessageExt msg : msgs) {
                
                System.out.println(new String(msg.getBody()));;
            }
            return ConsumeConcurrentlyStatus.CONSUME_SUCCESS;
        }
}
