配置Fanout规则

package com.china.rabbitmq.excise.utils;


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 FanoutRabbitConfig {

//    定义队列

    @Bean
    public Queue Q1Message() {
        return new Queue("fanout.Q1");
    }

    @Bean
    public Queue Q2Message() {
        return new Queue("fanout.Q2");
    }

    @Bean
    public Queue Q3Message() {
        return new Queue("fanout.Q3");
    }

    //    定义交换机
    @Bean
    FanoutExchange fanoutExchange() {
        return new FanoutExchange("fanoutExchange");
    }

    //分别进行绑定
    @Bean

发送者

package com.china.rabbitmq.excise.services;

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

@Component
public class Producer {

    @Autowired

        System.out.println("Fanout Sender:\t"+context);
        this.rabbitTemplate.convertAndSend("fanoutExchange","",context);
    }
}

接收者

package com.china.rabbitmq.excise.services;

import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

@Component
public class Consumer {

    }



}

单元测试

@SpringBootTest
class RabbitmqApplicationTests {

	@Autowired
	Producer producer;

	@Test
	void contextLoads() throws InterruptedException {

		producer.produce();
		Thread.sleep(10000);
	}

}
