怎么进行网站推广云指官网

1.需要阿里云开通商业版RocketMQ

普通消息新建普通主题,普通组,延迟消息新建延迟消息主题,延迟消息组

2.结构目录

3.引入依赖

<!--阿里云RocketMq整合--><dependency><groupId>com.aliyun.openservices</groupId><artifactId>ons-client</artifactId><version>1.8.8.5.Final</version></dependency>

4.延迟消息配置

import com.aliyun.openservices.ons.api.PropertyKeyConst;
import com.aliyun.openservices.ons.api.batch.BatchMessageListener;
import com.aliyun.openservices.ons.api.bean.BatchConsumerBean;
import com.aliyun.openservices.ons.api.bean.Subscription;
import com.atkj.devicewx.config.MqConfig;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;import java.util.HashMap;
import java.util.Map;
import java.util.Properties;/*** 延迟消息配置类*/
@Configuration
public class BatchConsumerClient {@Autowiredprivate MqConfig mqConfig;@Autowiredprivate BatchDemoMessageListener messageListener;@Bean(initMethod = "start", destroyMethod = "shutdown")public BatchConsumerBean buildBatchConsumer() {BatchConsumerBean batchConsumerBean = new BatchConsumerBean();//配置文件Properties properties = mqConfig.getMqPropertie();properties.setProperty(PropertyKeyConst.GROUP_ID, mqConfig.getDelayGroupId());//将消费者线程数固定为20个 20为默认值properties.setProperty(PropertyKeyConst.ConsumeThreadNums, "20");batchConsumerBean.setProperties(properties);//订阅关系Map<Subscription, BatchMessageListener> subscriptionTable = new HashMap<Subscription, BatchMessageListener>();Subscription subscription = new Subscription();subscription.setTopic(mqConfig.getDelayTopic());subscription.setExpression(mqConfig.getDelayTag());subscriptionTable.put(subscription, messageListener);//订阅多个topic如上面设置batchConsumerBean.setSubscriptionTable(subscriptionTable);return batchConsumerBean;}}

import com.aliyun.openservices.ons.api.Action;
import com.aliyun.openservices.ons.api.ConsumeContext;
import com.aliyun.openservices.ons.api.Message;
import com.aliyun.openservices.ons.api.batch.BatchMessageListener;
import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Component;import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.List;/*** 延迟消息消费者*/
@Slf4j
@Component
public class BatchDemoMessageListener implements BatchMessageListener {@Overridepublic Action consume(final List<Message> messages, final ConsumeContext context) {log.info("消费者收到消息大小:"+messages.size());for (Message message : messages) {byte[] body = message.getBody();String s = new String(body);Date date = new Date();SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");String formatTime = sdf.format(date);System.out.println("接收到消息时间:"+formatTime);log.info("接收到消息内容:"+s);}try {//do something..return Action.CommitMessage;} catch (Exception e) {//消费失败return Action.ReconsumeLater;}}
}

5.MQ配置类

import com.aliyun.openservices.ons.api.PropertyKeyConst;
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;import java.util.Properties;@Data
@Configuration
@ConfigurationProperties(prefix = "rocketmq")
public class MqConfig {private String accessKey;private String secretKey;private String nameSrvAddr;private String topic;private String groupId;private String tag;private String orderTopic;private String orderGroupId;private String orderTag;private String delayTopic;private String delayGroupId;private String delayTag;public Properties getMqPropertie() {Properties properties = new Properties();properties.setProperty(PropertyKeyConst.AccessKey, this.accessKey);properties.setProperty(PropertyKeyConst.SecretKey, this.secretKey);properties.setProperty(PropertyKeyConst.NAMESRV_ADDR, this.nameSrvAddr);return properties;}}

6.YML配置

## 阿里云RocketMQ配置

7.普通消息配置

import com.aliyun.openservices.ons.api.MessageListener;

//效果和 DemoMessageListener 一致

}

7.order没用到

import com.aliyun.openservices.ons.api.PropertyKeyConst;
import com.aliyun.openservices.ons.api.bean.OrderConsumerBean;
import com.aliyun.openservices.ons.api.bean.Subscription;
import com.aliyun.openservices.ons.api.order.MessageOrderListener;

8.事务消息没用到

import com.aliyun.openservices.ons.api.Message;
import com.aliyun.openservices.ons.api.transaction.LocalTransactionChecker;
import com.aliyun.openservices.ons.api.transaction.TransactionStatus;
import lombok.extern.slf4j.Slf4j;

@Slf4j
@Component
public class DemoLocalTransactionChecker implements LocalTransactionChecker {@Overridepublic TransactionStatus check(Message msg) {log.info("开始回查本地事务状态");return TransactionStatus.CommitTransaction; //根据本地事务状态检查结果返回不同的TransactionStatus}
}

import com.aliyun.openservices.ons.api.bean.TransactionProducerBean;
import com.atkj.devicewx.config.MqConfig;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;/*** 事务消息配置类*/
@Configuration
public class TransactionProducerClient {@Autowiredprivate MqConfig mqConfig;@Autowiredprivate DemoLocalTransactionChecker localTransactionChecker;@Bean(initMethod = "start", destroyMethod = "shutdown")public TransactionProducerBean buildTransactionProducer() {TransactionProducerBean producer = new TransactionProducerBean();producer.setProperties(mqConfig.getMqPropertie());producer.setLocalTransactionChecker(localTransactionChecker);return producer;}}

优化部分

每次发送消息都要创建生产者,效率低下
使用单例优化

其他不变
