RocketMQ (五) Springboot 整合 RocketMQ 收发消息样例

pom文件

创建 springboot 项目，添加rocketmq-spring-boot-starter依赖。

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

yml 配置

application.yml

application-demo1.yml
使用 demo1 profile 指定生产者组组名

application-demo2.yml
使用 demo2 profile 指定生产者组组名

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

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.support.MessageBuilder;
import org.springframework.stereotype.Component;

@Component
public class Producer {
@Autowired
private RocketMQTemplate t;

public void send() {
    //发送消息
    t.convertAndSend("Topic1:TagA", "Hello world! ");

    //发送spring的Message
    t.send("Topic1:TagA", MessageBuilder.withPayload("Hello world! ").build());

    //发送异步消息
    t.asyncSend("Topic1:TagA", "Hello world!", 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");
}

}

测试类，需要放在 test 文件夹
这个测试激活 demo1 profile

demo 2
发送事务消息
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> msg = MessageBuilder.withPayload("Hello world!").build();

    t.sendMessageInTransaction("Topic2:TagA", msg, 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;
    }
}

}
