SpringBoot集成RockerMQ

1.引入依赖

<dependency><groupId>org.apache.rocketmq</groupId><artifactId>rocketmq-spring-boot-starter</artifactId><version>2.2.0</version>
</dependency>

2.配置服务器地址

#Rocketmq配置
rocketmq.name-server=192.168.11.99:9876
# 必须指定生产者组
rocketmq.producer.group=group01
# 消息发送超时时长，默认3s
rocketmq.producer.send-message-timeout=3000
# 同步发送消息失败重试次数，默认2
rocketmq.producer.retry-times-when-send-failed=3
# 异步发送消息失败重试次数，默认2
rocketmq.producer.retry-times-when-send-async-failed=3

3.创建生产者

package com.by.rocketmq.consumer;import lombok.extern.slf4j.Slf4j;
import org.apache.rocketmq.client.consumer.DefaultMQPushConsumer;
import org.apache.rocketmq.spring.annotation.RocketMQMessageListener;
import org.apache.rocketmq.spring.core.RocketMQListener;
import org.apache.rocketmq.spring.core.RocketMQPushConsumerLifecycleListener;
import org.springframework.stereotype.Component;@Component
@Slf4j
@RocketMQMessageListener(topic = "topic_01",consumerGroup = "group_205")
public class RocketMqConsumer implements RocketMQListener<String>, RocketMQPushConsumerLifecycleListener {@Overridepublic void onMessage(String massage) {log.info("消费者1:{}"+massage);}@Overridepublic void prepareStart(DefaultMQPushConsumer consumer) {// 最大重试次数consumer.setMaxReconsumeTimes(2);// 设置消费者的属性consumer.setPullBatchSize(250);// 一次抓取的数量}
}

4.创建消费者

package com.by.rocketmq.provider;import com.by.moder.RegisterOk;
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 RocketMqProvider {@Autowiredprivate RocketMQTemplate rocketMQTemplate;public void send(String msg){Message<String> msg1 = MessageBuilder.withPayload(msg).build();//rocketMQTemplate.send("topic_01",msg1);//rocketMQTemplate.convertAndSend("topic_01",msg);//String destination, Message<?> message, long timeout  延迟消费rocketMQTemplate.syncSend("topic_01", msg1,3000,3);}}

测试

package com.by;import com.by.moder.RegisterOk;
import com.by.rocketmq.provider.RocketMqProvider;
import lombok.extern.slf4j.Slf4j;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;import java.io.IOException;@Slf4j
@SpringBootTest
class RocketMqTests {@AutowiredRocketMqProvider rocketMqProvider;@Testvoid Test1() throws IOException {//RegisterOk build = RegisterOk.builder().id(1).build();//String s = JSONUtil.toJsonStr(build);for (int i = 1; i <=10 ; i++) {rocketMqProvider.send("你好++"+i+"++");log.info("发送成功："+i);}System.in.read();}// 延迟消费@Testvoid Test2() throws IOException {rocketMqProvider.send("你好++++");log.info("发送成功："+1);System.in.read();}}

死信队列

@Service
@Slf4j
@RocketMQMessageListener(consumerGroup = "${rocketmq.consumer.group}", topic = "topic_01")
public class Consumer  implements RocketMQListener<String>, RocketMQPushConsumerLifecycleListener {@Overridepublic void onMessage(String message) {System.out.println("Received message: " + message);log.info("Received message: " + message);;throw  new RuntimeException("test");}@Overridepublic void prepareStart(DefaultMQPushConsumer consumer) {// 设置最大重试次数consumer.setMaxReconsumeTimes(2);// 如下，设置其它consumer相关属性consumer.setPullBatchSize(16);}
}
