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;@Componentpublic 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;@SpringBootApplicationpublic 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;@Componentpublic 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;@SpringBootApplicationpublic 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(); } }}
