本文介绍了一个基于Direct路由模式的RabbitMQ示例，通过生产者发送不同类型的消息到交换机，并由两个消费者根据绑定的不同路由键来接收特定类型的消息。

生产者：

package org.example.Direct;

import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.MessageProperties;
import java.io.IOException;
import org.example.RabbitMQUtils;
import org.junit.Test;

public class Provider3 {

  @Test
  public void sendmessage() throws IOException {
    //获取连接对象
    Connection connection = RabbitMQUtils.getConnection();
    //获取连接中通道
    Channel channel = connection.createChannel();
    //参数1 交换机名称  参数2 类型
    channel.exchangeDeclare("logs_direct", "direct");
    String routingkey="info";
    //发布消息
    channel.basicPublish("logs_direct", routingkey, MessageProperties.PERSISTENT_TEXT_PLAIN,
        ("张强测试direct:").getBytes());

    RabbitMQUtils.closeConnectionFactory(channel, connection);


  }

}

消费者1：

package org.example.Direct;

import com.rabbitmq.client.AMQP.BasicProperties;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.DefaultConsumer;
import com.rabbitmq.client.Envelope;
import java.io.IOException;
import org.example.RabbitMQUtils;

public class consum11 {

  public static void main(String[] args) throws IOException {
    Connection connection = RabbitMQUtils.getConnection();
    Channel channel = connection.createChannel();
    //参数1 交换机名称  参数2 类型
    channel.exchangeDeclare("logs_direct", "direct");
  //临时队列名称
    String queneName=channel.queueDeclare().getQueue();
    //基于route 绑定交换机和队列
    channel.queueBind(queneName,"logs_direct","error");

    //autoAck 置位 false
    channel.basicConsume(queneName, true, new DefaultConsumer(channel) {
      @Override
      public void handleDelivery(String consumerTag, Envelope envelope, BasicProperties properties,
          byte[] body) throws IOException {

        System.out.println("消费者-1：" + new String(body));

      }
    });
  }
}

消费者2：

package org.example.Direct;

import com.rabbitmq.client.AMQP.BasicProperties;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.DefaultConsumer;
import com.rabbitmq.client.Envelope;
import java.io.IOException;
import org.example.RabbitMQUtils;

/**

 */
public class consum22 {

  public static void main(String[] args) throws IOException {
    Connection connection = RabbitMQUtils.getConnection();
    Channel channel = connection.createChannel();
    //参数1 交换机名称  参数2 类型
    channel.exchangeDeclare("logs_direct", "direct");
  //临时队列名称
    String queneName=channel.queueDeclare().getQueue();
    //基于route 绑定交换机和队列
    channel.queueBind(queneName,"logs_direct","error");
    channel.queueBind(queneName,"logs_direct","info");
    channel.queueBind(queneName,"logs_direct","warning");

    //autoAck 置位 false
    channel.basicConsume(queneName, true, new DefaultConsumer(channel) {
      @Override
      public void handleDelivery(String consumerTag, Envelope envelope, BasicProperties properties,
          byte[] body) throws IOException {

        System.out.println("消费者-1：" + new String(body));

      }
    });
  }
}

运行看效果：

生产者发送的是

String routingkey="info";

info类型；

消费者1 绑定的是：error

channel.queueBind(queneName,"logs_direct","error");

消费者2 绑定的是：error ,info,warning

//基于route 绑定交换机和队列
channel.queueBind(queneName,"logs_direct","error");
channel.queueBind(queneName,"logs_direct","info");
channel.queueBind(queneName,"logs_direct","warning");

消费者1 没有订阅error，所以接收不到消息
