广播消息:
一个点发送,所有有监听订阅的程序都能收到消息。
应用场景:一个配置更新了,其他点都需要知道配置更新需加载。
mq创建
主要是创建组时与队列有点区别
mqadmin updateSubGroup -c rocketmq-cluster -d true -g broad-string-consumer -n "192.168.3.252:9876;192.168.3.253:9876"
mqadmin updateSubGroup -c rocketmq-cluster -d true -g broad-string-consumer -n "192.168.3.252:9876;192.168.3.253:9876"
mqadmin updateTopic -c rocketmq-cluster -t TOPIC-SYS-ACC-BIZ-BROADCAST
mqadmin updateSubGroup -c rocketmq-cluster -d true -g GID-ACC-BIZBROADCAST
生产者
产生消息与产生普通消息一样
@Component
public class RocketTest extends BaseTest{
@Autowired
private AccBizSender accBizSender;
@Test
public void accBizSenderTest() throws Exception {
for (int i=0;i<10;i++) {
BaseMqRequest baseMqRequest = new BaseMqRequest();
baseMqRequest.setBizType("sendTest");
baseMqRequest.setData("{i="+i+"}");
accBizSender.sendMessageBroadcast(baseMqRequest);
}
MyDateUtil.sleep(1000000);
}
}
消费者
消息模式必须指定
messageModel = MessageModel.BROADCASTING
import org.apache.rocketmq.spring.annotation.MessageModel;
import org.apache.rocketmq.spring.annotation.RocketMQMessageListener;
import org.springframework.stereotype.Component;
import com.ccjr.commons.constants.RocketMqConstants;
import lombok.extern.slf4j.Slf4j;
@Slf4j
@Component
@RocketMQMessageListener(topic = RocketMqConstants.TOPIC_SYS_ACC_BIZ_BROADCAST,
consumerGroup = RocketMqConstants.G_TAG_ACC_BIZBROADCAST,
selectorExpression = RocketMqConstants.TAG_ACC_BIZBROADCAST,
messageModel = MessageModel.BROADCASTING)
public class AccBizListener extends BaseListener {
@Override
public void onMessageExec(String boContext) {
super.initMqMsg(RocketMqConstants.TOPIC_SYS_ACC_BIZ_BROADCAST, RocketMqConstants.G_TAG_ACC_BIZBROADCAST, RocketMqConstants.TAG_ACC_BIZBROADCAST);
log.info("接收广播消息ACC::"+boContext);
}
}
