Java에서 Rabbitmq를 원격으로 연결하고 호출하는 방법을 공유하시겠습니까?

RabbitMQ 원격 호출 테스트는 외부 머신 192.168.174.132에서 RabbitMQ를 사용하세요. 사용하기 전에 원격 호출을 구성해야 합니다. 작업 과정은 블로그 게시물 "RabbitMQ에 대한 원격 액세스 문제 해결"을 참조하세요.

IDEA를 열고 Maven 프로젝트를 만듭니다(Java는 괜찮습니다).

rabbitmq에 원격으로 접속하려면 /etc/rabbitmq/rabbitmq.conf를 편집하고 다음 내용을 추가해야 합니다.

[
  {rabbit, [{tcp_listeners, [5672]}, {loopback_users, ["asdf"]}]}
 ]

관리자 역할 추가

rabbitmqctl set_user_tags openstack administrator

추상 대기열 생성 EndPoint.java

package com.zhenqi;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;
/**
 * Created by wuming on 2017/7/16.
 */
public abstract class EndPoint {

  protected Channel channel;
  protected Connection connection;
  protected String endPointName;

  public EndPoint(String endpointName) throws Exception {

    this.endPointName = endpointName;

    //创建一个连接工厂 connection factory
    ConnectionFactory factory = new ConnectionFactory();

    //设置rabbitmq-server服务IP地址
    factory.setHost("192.168.146.128");
    factory.setUsername("openstack");
    factory.setPassword("rabbitmq");
    factory.setPort(5672);
    factory.setVirtualHost("/");

    //得到 连接
    connection = factory.newConnection();

    //创建 channel实例
    channel = connection.createChannel();

    channel.queueDeclare(endpointName, false, false, false, null);
  }

  /**
   * 关闭channel和connection。并非必须，因为隐含是自动调用的。
   * @throws IOException
   */
  public void close() throws Exception{
    this.channel.close();
    this.connection.close();
  }
}

Producer Producer.java

생산자 클래스의 작업은 대기열

package com.zhenqi;
import org.apache.commons.lang.SerializationUtils;
import java.io.Serializable;
/**

 */
public class Producer extends EndPoint {

  public Producer(String endpointName) throws Exception {
    super(endpointName);
  }

  public void sendMessage(Serializable object) throws Exception {
    channel.basicPublish("",endPointName, null, SerializationUtils.serialize(object));
  }
}

Consumer QueueConsumer에 메시지를 쓰는 것입니다. java

소비자는 스레드 모드에서 실행할 수 있으며 다양한 이벤트에 대해 다양한 콜백 함수를 사용할 수 있습니다. 그 중 가장 중요한 것은 새 메시지가 도착할 때 이벤트를 처리하는 것입니다.

package com.zhenqi;

import com.rabbitmq.client.AMQP;
import com.rabbitmq.client.Consumer;
import com.rabbitmq.client.Envelope;
import com.rabbitmq.client.ShutdownSignalException;
import org.apache.commons.lang.SerializationUtils;
import org.apache.log4j.Logger;
import java.io.IOException;
import java.util.HashMap;
import java.util.Map;
/**
 * Created by wuming on 2017/7/16.
 */
public class QueueConsumer extends EndPoint implements Runnable, Consumer {

  private Logger LOG=Logger.getLogger(QueueConsumer.class);

  public QueueConsumer(String endpointName) throws Exception {
    super(endpointName);
  }

  public void handleConsumeOk(String s) {

  }

  public void handleCancelOk(String s) {

  }

  public void handleCancel(String s) throws IOException {

  }

  public void handleShutdownSignal(String s, ShutdownSignalException e) {

  }

  public void handleRecoverOk(String s) {
    LOG.info("Consumer "+s +" registered");
  }

  public void handleDelivery(String s, Envelope envelope, AMQP.BasicProperties basicProperties, byte[] bytes) throws IOException {
    Map map = (HashMap) SerializationUtils.deserialize(bytes);
    LOG.info("Message Number "+ map.get("message number") + " received.");
  }

  public void run() {
    try{
      channel.basicConsume(endPointName, true,this);
    }catch(IOException e){
      e.printStackTrace();
    }
  }
}

테스트

소비자 스레드를 실행한 다음 소비자가 가져갈 대량의 메시지 생성을 시작합니다

package com.zhenqi;

import java.util.HashMap;

/**
 * Created by wuming on 2017/7/16.
 */
public class TestRabbitmq {

  public static void main(String[] args){
    try{
      QueueConsumer consumer = new QueueConsumer("queue");
      Thread consumerThread = new Thread(consumer);
      consumerThread.start();

      Producer producer = new Producer("queue");

      for (int i = 0; i < 100000; i++){
        HashMap message = new HashMap();
        message.put("message number", i);
        producer.sendMessage(message);
        System.out.println("Message Number "+ i +" sent.");
      }
    }catch(Exception e){
      e.printStackTrace();
    }

  }
}
