Springboot 整合 RocketMQ 收发消息

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;
        }
    }

}
