**1. 「 * 」的使用：**

生產者：java

package com.toov5.topic;

import java.io.IOException;
import java.util.concurrent.TimeoutException;

import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.toov5.utils.MQConnectionUtils;

//生產者 交換機類型 producerFanout類型
public class TopicProducer {
    //交換機名稱
     private static final String EXCHANGE_NAME = "my_topic"; 
     public static void main(String[] args) throws IOException, TimeoutException {
        //創建MQ鏈接
         Connection connection = MQConnectionUtils.newConnection();
        //建立通道
          Channel channel = connection.createChannel();
          //生產者綁定交換機
          channel.exchangeDeclare(EXCHANGE_NAME, "topic");  //交換機名稱  交換機類型
          String routingKey="log.email";    //消息只會給郵件類型的           //建立對應的消息 
          String msString = "my_Routing_destination_msg"+routingKey;
          //經過頻道 發送消息
          System.out.println("生產者投遞消息："+msString);
          channel.basicPublish(EXCHANGE_NAME, routingKey, null, msString.getBytes());
          //關閉通道 和 鏈接
          channel.close();
          connection.close();
    }
    
}
