关于RokectMQ消息队列的运用

自己封装的RocketUtil

public class RocketMQUtils {

    public static Producer getProducer(String producerId){
        Properties properties = new Properties();
        //您在控制台创建的Producer ID
        properties.put(PropertyKeyConst.ProducerId,"PID_T_PaymentCallback_CMB");
        // AccessKey 阿里云身份验证，在阿里云服务器管理控制台创建
        properties.put(PropertyKeyConst.AccessKey,"LTAIIxdTlDBAT7N3");
        // SecretKey 阿里云身份验证，在阿里云服务器管理控制台创建
        properties.put(PropertyKeyConst.SecretKey, "HYeesDmlmFadiYCZ7TA0pIiCGu4PGk");
        //设置发送超时时间，单位毫秒
        properties.setProperty(PropertyKeyConst.SendMsgTimeoutMillis, "3000");
        // 设置 TCP 接入域名（此处以公共云生产环境为例）
        properties.put(PropertyKeyConst.ONSAddr, "http://onsaddr-internet.aliyun.com/rocketmq/nsaddr4client-internet");
        Producer producer = ONSFactory.createProducer(properties);
        // 在发送消息前，必须调用start方法来启动Producer，只需调用一次即可
        producer.start();
        System.out.println("haha");
        return producer;
    }
    //创建一个消息
    public static Message createMsg(String topic, String tags, Object msg){
        return new Message(topic,tags,msg.toString().getBytes());
    }


    //客户端订阅消息
    public static Consumer getCoustomer(String consumerId, String topic){
        Properties properties = new Properties();
        // 您在控制台创建的 Consumer ID
        properties.put(PropertyKeyConst.ConsumerId, "CID_T_PaymentCallback_CMB");
        // AccessKey 阿里云身份验证，在阿里云服务器管理控制台创建
        properties.put(PropertyKeyConst.AccessKey, "LTAIIxdTlDBAT7N3");
        // SecretKey 阿里云身份验证，在阿里云服务器管理控制台创建
        properties.put(PropertyKeyConst.SecretKey, "HYeesDmlmFadiYCZ7TA0pIiCGu4PGk");
        // 设置 TCP 接入域名（此处以公共云生产环境为例）
        properties.put(PropertyKeyConst.ONSAddr,
                "http://onsaddr-internet.aliyun.com/rocketmq/nsaddr4client-internet");
        // 集群订阅方式 (默认)
        // properties.put(PropertyKeyConst.MessageModel, PropertyValueConst.CLUSTERING);
        // 广播订阅方式
        // properties.put(PropertyKeyConst.MessageModel, PropertyValueConst.BROADCASTING);
        Consumer consumer = ONSFactory.createConsumer(properties);
        consumer.subscribe(topic, "*", new MessageListener() { //订阅多个Tag
            public Action consume(Message message, ConsumeContext context) {
                System.out.println("Receive: " + message);
                System.out.println(new String(message.getBody()));
                return Action.CommitMessage;
            }
        });
        consumer.start();
        System.out.println("Consumer Started");
        return consumer;
    }
