不哔哔，直接上代码

主要是 消费者添加配置

一，把配置放在配置中心（放在消费服务上也可以）

listener.direct.auto-startup设置为false,

然后添加 rabbitmq.start 作为启动属性

spring:
  rabbitmq:
    host: 127.0.0.1
    port: 5672
    username: guest
    password: guest
    listener:
      direct:
        auto-startup: false

rabbitmq:
  start: true

然后在消费服务的启动类   xxxxxApplication.class中添加

package com.test.service1;

import com.test.rabbitmq.RabbitmqApplication;
import org.springframework.amqp.rabbit.listener.RabbitListenerEndpointRegistry;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

import javax.annotation.Resource;

@SpringBootApplication
@EnableEurekaClient
public class Service1Application {
    public static void main(String[] args) {
        ApplicationContext context=SpringApplication.run(Service1Application.class, args);
        RabbitMQStart rabbitMQRun = context.getBean(RabbitMQStart.class);
        rabbitMQRun.start();
    }

    @Bean
    public RabbitMQStart rabbitMQRun() {
        return new RabbitMQStart();
    }
    private static class RabbitMQStart {
        //为了在main中的static方法中使用@value注解只能用这种办法
        @Value("${rabbitmq.start}")
        private Boolean rabbitmqStart;

        @Resource
        RabbitListenerEndpointRegistry rabbitListenerEndpointRegistry;
        public void start() {
            if(rabbitmqStart)
                rabbitListenerEndpointRegistry.start();
            else
                rabbitListenerEndpointRegistry.stop();
            System.out.println("=================== Rabbitmq:"+rabbitmqStart+"===================");
        }
    }
}

二，测试：

rabbitmq.start = true 时

rabbitmq.start = false 时
