topic模式 RoutingKey 按照英文单词点号多拼接规则填充。其中消费者匹配规则时候 * 代表一个单词,#表示多个单词
消费者C1的RoutingKey 规则按照*.orange.*
匹配 绑定队列Q1
package com.esint.rabbitmq.work05;
import com.esint.rabbitmq.RabbitMQUtils;
import com.rabbitmq.client.BuiltinExchangeType;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.DeliverCallback;
public class ReceiveLogsTopic01 {
public static final String EXCHANGE_NAME = "topic";
public static void main(String[] args) throws Exception {
Channel channel = RabbitMQUtils.getChannel();
channel.exchangeDeclare(EXCHANGE_NAME, BuiltinExchangeType.TOPIC);
String queueName = "Q1";
channel.queueDeclare(queueName,false,false,false,null);
channel.queueBind(queueName,EXCHANGE_NAME,"*.orange.*");
System.out.println("Q1队列等待接受消息...");
DeliverCallback deliverCallback = (deliverTag,mes)->{
System.out.println("打印ReceiveLogsTopic01控制台消息:" + new String(mes.getBody(),"UTF-8"));
System.out.println("接收队列:" + queueName + " 绑定键:" + mes.getEnvelope().getRoutingKey());
};
channel.basicConsume(queueName,true,deliverCallback,deliverTag->{});
}
}
消费者C2的RoutingKey 规则按照*.rabbit.* 和 lazy.#
匹配 绑定队列Q2
package com.esint.rabbitmq.work05;
import com.esint.rabbitmq.RabbitMQUtils;
import com.rabbitmq.client.BuiltinExchangeType;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.DeliverCallback;
public class ReceiveLogsTopic02 {
public static final String EXCHANGE_NAME = "topic";
public static void main(String[] args) throws Exception {
Channel channel = RabbitMQUtils.getChannel();
channel.exchangeDeclare(EXCHANGE_NAME, BuiltinExchangeType.TOPIC);
String queueName = "Q2";
channel.queueDeclare(queueName,false,false,false,null);
channel.queueBind(queueName,EXCHANGE_NAME,"*.*.rabbit");
channel.queueBind(queueName,EXCHANGE_NAME,"lazy.#");
System.out.println("Q2队列等待接受消息...");
DeliverCallback deliverCallback = (deliverTag,mes)->{
System.out.println("打印ReceiveLogsTopic01控制台消息:" + new String(mes.getBody(),"UTF-8"));
System.out.println("接收队列:" + queueName + " 绑定键:" + mes.getEnvelope().getRoutingKey());
};
channel.basicConsume(queueName,true,deliverCallback,deliverTag->{});
}
}
