RocketMq 之 java rocket client

maven依赖:

<dependency>
    <groupId>org.apache.rocketmq</groupId>
    <artifactId>rocketmq-client</artifactId>
    <version>4.4.0</version>
</dependency>

先用命令建一个topic:

sh mqadmin updateTopic -b 192.168.71.170:10911 -n 192.168.71.170:9876 -t TopicTest

查看:

sh mqadmin topicList -n 192.168.71.170:9876

输出：

[root@localhost bin]# sh mqadmin topicList -n 192.168.71.170:9876
RocketMQLog:WARN No appenders could be found for logger (io.netty.util.internal.PlatformDependent0).

Producer.java:

import org.apache.rocketmq.client.producer.DefaultMQProducer;
import org.apache.rocketmq.client.producer.SendResult;
import org.apache.rocketmq.common.message.Message;

public class Producer {
    public static void main(String[] args) throws Exception {
        DefaultMQProducer producer = new DefaultMQProducer("ProducerGroup");
        producer.setNamesrvAddr("192.168.71.170:9876");
        //producer.set
        producer.start();
        for(int i= 0; i <100; i++){
            Message message = new Message("TopicTest", "TagA", ("hello RocketMQ" + i).getBytes("UTF-8"));
            SendResult send = producer.send(message);
            System.out.println(send);
        }
        producer.shutdown();
    }
}

 主要三个参数要指定，ProducerGroup(组), namesrvaddr, 和topicname。

输出结果:
