Springboot controls the startup of rabbitmq through configuration files

No, beep, code

Mainly for consumers to add configuration

1.Put the configuration in the configuration center (it can also be put on the consumer service)

listener.direct.auto -Startup is set to false,

Then add rabbitmq.start As startup property


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

rabbitmq:
  start: true

Then in the consumer service startup class xxxxxApplication.class Add in

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 {
        //In order to use the @value annotation in the static method in main only this way can be used
        @Value("${rabbitmq.start}")
        private Boolean rabbitmqStart;

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

2.Test:

rabbitmq.start =When true

rabbitmq.start =When false
