config配置文件：

package org.example.config;

import org.springframework.amqp.core.TopicExchange;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * 主题交换机
 * topic策略可以根据routingKey的规则（通配符方式）进行去匹配队列进行转发规则为*.#.*
 */
@Configuration
public class RabbitTopicConfig
{


    public final static String TOPIC_NAME = "amqp-topic";


    @Bean
    TopicExchange topicExchange()
    {

        return new TopicExchange(TOPIC_NAME,true,false);

    }


}

 

 

 

 

 

 

 

 

发送：

package org.example.sender;

import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

/**
 * 消息生产者 发送消息
 */
@Component
public class MessageSender {

    @Autowired
    RabbitTemplate rabbitTemplate;

    /**
     * 发送消息
     * @param info
     */
    public void send(String info)
    {

        System.out.println("发送消息>>>"+info);


        rabbitTemplate.convertAndSend("amqp-topic","huawei.a",info);
    }

}

 

 

 

 

 

 

 

 

 

 

 

触发：

package org.example.controller;

import org.example.sender.MessageSender;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**

@RestController
public class IndexController {

    @Autowired
    MessageSender messageSender;

    @RequestMapping("/index")
    public String index()
    {

        messageSender.send("中国——路由——华为");
        return "SUCCESS";
