這篇文章主要介紹了Springboot?整合?RocketMQ?收發(fā)消息,本文給大家介紹的非常詳細(xì)，對大家的學(xué)習(xí)或工作具有一定的參考借鑒價(jià)值，需要的朋友可以參考下

Springboot 整合 RocketMQ 收發(fā)消息

創(chuàng)建springboot項(xiàng)目

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

<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 指定生產(chǎn)者組組名

rocketmq:
  producer:
    group: producer-demo1

application-demo2.yml

使用 demo2 profile 指定生產(chǎn)者組組名

rocketmq:
  producer:
    group: producer-demo2

測試

demo 1

發(fā)送普通消息
發(fā)送 Spring 的通用 Message 對象
發(fā)送異步消息
發(fā)送順序消息

生產(chǎn)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(){
        //發(fā)送同步消息
        t.convertAndSend("Topic1:TagA", "Hello world! ");
        //發(fā)送spring的Message
        Message<String> message = MessageBuilder.withPayload("Hello Spring message! ").build();
        t.send("Topic1:TagA",message);
        //發(fā)送異步消息
        t.asyncSend("Topic1:TagA", "hello world asyn", new SendCallback() {
            @Override
            public void onSuccess(SendResult sendResult) {
                System.out.println("發(fā)送成功");
            }
            @Override
            public void onException(Throwable throwable) {
                System.out.println("發(fā)送失敗");
            }
        });
        //發(fā)送順序消息
        t.syncSendOrderly("Topic1", "98456237,創(chuàng)建", "98456237");
        t.syncSendOrderly("Topic1", "98456237,支付", "98456237");
        t.syncSendOrderly("Topic1", "98456237,完成", "98456237");
    }
}

消費(fèi)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);
    }
}

主類

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);
    }
}

測試類

需要放在 test 文件夾

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

發(fā)送事務(wù)消息

生產(chǎn)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();
        //一旦發(fā)送消息，則執(zhí)行監(jiān)聽器
        t.sendMessageInTransaction("Topic2",message,null);
    }
    @RocketMQTransactionListener
    class Lis implements RocketMQLocalTransactionListener {
        @Override
        public RocketMQLocalTransactionState executeLocalTransaction(Message message, Object o) {
            System.out.println("執(zhí)行本地事務(wù)");
            return RocketMQLocalTransactionState.UNKNOWN;
        }

        @Override
        public RocketMQLocalTransactionState checkLocalTransaction(Message message) {
            System.out.println("執(zhí)行事務(wù)回查");
            return RocketMQLocalTransactionState.COMMIT;
        }
    }

}
