MyRabbitConfig

package org.example.config;

import org.springframework.amqp.core.Binding;
import org.springframework.amqp.core.BindingBuilder;
import org.springframework.amqp.core.FanoutExchange;
import org.springframework.amqp.core.Queue;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class MyRabbitConfig
{

    public final static String FANOUT_NAME ="amqp-fanout";

    @Bean
    FanoutExchange fanoutExchange(){
        return new FanoutExchange(FANOUT_NAME,true,false);
    }


}

发送消息：

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-fanout","",info);
    }

}

通过服务发送：

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;

/**
 * @Auther: [email protected]
 * @Date: 2020/10/4 11:34
 */
@RestController
public class IndexController {

    @Autowired
    MessageSender messageSender;

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

        messageSender.send("中国——生产者");
        return "SUCCESS";
    }
