RabbitMQ 路由模式即直接交换机

1.路由交换机

这种类型的工作方式是，消息只去到它绑定的routing key的队列中去

2.实战

（1）图示

 （2）代码实现

package com.rabbitmq.six;import com.rabbitmq.client.Channel;
import com.rabbitmq.utils.MqUtils;import java.io.IOException;
import java.util.Scanner;
import java.util.concurrent.TimeoutException;public class DirectLogs {private static final String EXCHANGE_NAME = "direct_logs";public static void main(String[] args) throws IOException, TimeoutException {Channel channel = MqUtils.getChannel();Scanner scanner = new Scanner(System.in);while(scanner.hasNext()) {String message = scanner.next();// 先测试info然后改成warning重启,然后改成error重启测试channel.basicPublish(EXCHANGE_NAME, "info", null ,message.getBytes("UTF-8"));System.out.println("生产者发出消息：" + message);}}
}

package com.rabbitmq.six;import com.rabbitmq.client.BuiltinExchangeType;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.DeliverCallback;
import com.rabbitmq.utils.MqUtils;import java.io.IOException;
import java.util.concurrent.TimeoutException;public class ReceiveLogsDirect01 {private static final String EXCHANGE_NAME = "direct_logs";public static void main(String[] args) throws IOException, TimeoutException {Channel channel = MqUtils.getChannel();// 声明交换机-直接交换机(Direct)channel.exchangeDeclare(EXCHANGE_NAME, BuiltinExchangeType.DIRECT);// 声明队列channel.queueDeclare("console", false, false,false, null);// 绑定交换机与队列channel.queueBind("console", EXCHANGE_NAME, "info");channel.queueBind("console", EXCHANGE_NAME, "warning");// 接收消息DeliverCallback deliverCallback = (consumerTag, message) -> {System.out.println("ReceiveLogsDirect01控制台打印接收到的消息：" + new String(message.getBody(), "UTF-8"));};channel.basicConsume("console",true, deliverCallback,consumerTag->{});}
}

package com.rabbitmq.six;import com.rabbitmq.client.BuiltinExchangeType;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.DeliverCallback;
import com.rabbitmq.utils.MqUtils;import java.io.IOException;
import java.util.concurrent.TimeoutException;public class ReceiveLogsDirect02 {private static final String EXCHANGE_NAME = "direct_logs";public static void main(String[] args) throws IOException, TimeoutException {Channel channel = MqUtils.getChannel();// 声明交换机-直接交换机(Direct)channel.exchangeDeclare(EXCHANGE_NAME, BuiltinExchangeType.DIRECT);// 声明队列channel.queueDeclare("disk", false, false,false, null);// 绑定交换机与队列channel.queueBind("disk", EXCHANGE_NAME, "error");// 接收消息DeliverCallback deliverCallback = (consumerTag, message) -> {System.out.println("ReceiveLogsDirect02控制台打印接收到的消息：" + new String(message.getBody(), "UTF-8"));};channel.basicConsume("disk",true, deliverCallback,consumerTag->{});}
}
