Springboot如何整合RocketMQ收发消息

这篇文章将为大家详细讲解有关Springboot如何整合RocketMQ收发消息，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。

Springboot 整合 RocketMQ 收发消息

创建springboot项目

pom.xml添加rocketmq-spring-boot-starter依赖。

<dependency>
    <groupId>org.apache.rocketmq</groupId>
    <artifactId>rocketmq-spring-boot-starter</artifactId>
    <version>2.1.0</version>
</dependency>

yml 配置

application.yml

rocketmq:
  name-server: 192.168.64.141:9876

application-demo1.yml

使用 demo1 profile 指定生产者组组名

rocketmq:
  producer:
    group: producer-demo1

application-demo2.yml

使用 demo2 profile 指定生产者组组名

rocketmq:
  producer:
    group: producer-demo2

测试

demo 1

• 发送普通消息

• 发送 Spring 的通用 Message 对象

• 发送异步消息

• 发送顺序消息

生产者

package cn.tedu.demo2.m1;
import org.apache.rocketmq.client.producer.SendCallback;
import org.apache.rocketmq.client.producer.SendResult;
import org.apache.rocketmq.spring.core.RocketMQTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.messaging.Message;
import org.springframework.messaging.support.MessageBuilder;
import org.springframework.stereotype.Component;
@Component
public class Producer {
    @Autowired
    private RocketMQTemplate t ;
    public  void send(){
        //发送同步消息
        t.convertAndSend("Topic1:TagA", "Hello world! ");
        //发送spring的Message
        Message<String> message = MessageBuilder.withPayload("Hello Spring message! ").build();
        t.send("Topic1:TagA",message);
        //发送异步消息
        t.asyncSend("Topic1:TagA", "hello world asyn", new SendCallback() {
            @Override
            public void onSuccess(SendResult sendResult) {
                System.out.println("发送成功");
            }
            @Override
            public void onException(Throwable throwable) {
                System.out.println("发送失败");
            }
        });
        //发送顺序消息
        t.syncSendOrderly("Topic1", "98456237,创建", "98456237");
        t.syncSendOrderly("Topic1", "98456237,支付", "98456237");
        t.syncSendOrderly("Topic1", "98456237,完成", "98456237");
    }
}

消费者

package cn.tedu.demo2.m1;
import org.apache.rocketmq.spring.annotation.RocketMQMessageListener;
import org.apache.rocketmq.spring.core.RocketMQListener;
import org.springframework.stereotype.Component;
@Component
@RocketMQMessageListener(topic = "Topic1",consumerGroup = "consumer-demo1")
public class Consumer  implements RocketMQListener<String> {
    @Override
    public void onMessage(String s) {
        System.out.println("收到"+s);
    }
}

主类

package cn.tedu.demo2.m1;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class Main {
    public static void main(String[] args) {
        SpringApplication.run(Main.class, args);
    }
}

测试类

需要放在 test 文件夹

激活 demo1 profile  @ActiveProfiles("demo1")

package cn.tedu.demo2.m1;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.ActiveProfiles;
@SpringBootTest
@ActiveProfiles("demo1")
public class Test1 {
    @Autowired
    private  Producer producer;
    @Test
    public void test1(){
        producer.send();
        try {
            Thread.sleep(5000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

demo 2

发送事务消息

生产者

package cn.tedu.demo2.m2;

import org.apache.rocketmq.spring.annotation.RocketMQTransactionListener;
import org.apache.rocketmq.spring.core.RocketMQLocalTransactionListener;
import org.apache.rocketmq.spring.core.RocketMQLocalTransactionState;
import org.apache.rocketmq.spring.core.RocketMQTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.messaging.Message;
import org.springframework.messaging.support.MessageBuilder;
import org.springframework.stereotype.Component;

@Component

public class Producer {

    @Autowired
    private RocketMQTemplate t;

    public void send(){
        Message<String> message = MessageBuilder.withPayload("Hello world").build();
        //一旦发送消息，则执行监听器
        t.sendMessageInTransaction("Topic2",message,null);
    }
    @RocketMQTransactionListener
    class Lis implements RocketMQLocalTransactionListener {
        @Override
        public RocketMQLocalTransactionState executeLocalTransaction(Message message, Object o) {
            System.out.println("执行本地事务");
            return RocketMQLocalTransactionState.UNKNOWN;
        }

        @Override
        public RocketMQLocalTransactionState checkLocalTransaction(Message message) {
            System.out.println("执行事务回查");
            return RocketMQLocalTransactionState.COMMIT;
        }
    }

}

消费者

package cn.tedu.demo2.m2;
import org.apache.rocketmq.spring.annotation.RocketMQMessageListener;
import org.apache.rocketmq.spring.core.RocketMQListener;
import org.springframework.stereotype.Component;
@Component
@RocketMQMessageListener(topic = "Topic2",consumerGroup = "consumer-demo2")
public class Consumer implements RocketMQListener<String> {
    @Override
    public void onMessage(String s) {
        System.out.println("收到"+s);
    }
}

主类

package cn.tedu.demo2.m2;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class Main {
    public static void main(String[] args) {
        SpringApplication.run(Main.class, args);
    }
}

测试类

package cn.tedu.demo2.m2;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.ActiveProfiles;
@SpringBootTest
@ActiveProfiles("demo2")
public class Test2 {
    @Autowired
    private  Producer producer;
    @Test
    public void  test1(){
        producer.send();
        //为了能够收到消费者消费的数据，这里通过休眠模拟等待时间
        try {
            Thread.sleep(30000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}
