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->{});}}

生产者顺序发送
