SpringBoot 动态监听RabbitMq队列

每个人遇到的场景可能不同，我本次遇到的就是队列已存在，我只需要监听即可。话不多说，上码！

application.properties

server.port=9009
spring.rabbitmq.host=192.168.1.118
spring.rabbitmq.port=5672
spring.rabbitmq.username=rabbit_dev
spring.rabbitmq.password=Dd.1111

RbMQReceiverHand.java

import org.springframework.amqp.core.Message;
import org.springframework.amqp.core.MessageListener;
import org.springframework.stereotype.Component;

/**
 * @author ...
 * @version 1.0
 * @date 2020/12/29 18:02
 * @Email [e-mail]
 * @DESC：
 */
/**
 * 监听接收消息
 */
@Component
public class RbMQReceiverHand implements MessageListener {

    @Override
    public void onMessage(Message message) {
        System.out.println("====接收到One" + message.getMessageProperties().getConsumerQueue() + "队列的消息=====");
        System.out.println(message.getMessageProperties().toString());
        System.out.println(new String(message.getBody()));
    }
}

RabbitMQConfig.java

import org.springframework.amqp.rabbit.connection.ConnectionFactory;
import org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;

import javax.annotation.Resource;

/**
 * @author ...
 * @version 1.0
 * @date 2020/12/29 18:05
 * @Email [e-mail]
 * @DESC：
 */
@Configuration
@Import(cn.hutool.extra.spring.SpringUtil.class)
public class RabbitMQConfig {
    @Resource
    RbMQReceiverHand RbMQReceiverHand;

    @Bean
    public Queue bw_Cabinet_OnOff() { return new Queue("Cabinet_OnOff",true); }
    @Bean
    public SimpleMessageListenerContainer messageListenerContainer(ConnectionFactory connectionFactory) {
        SimpleMessageListenerContainer container = new SimpleMessageListenerContainer();
        container.setConnectionFactory(connectionFactory);
        container.setQueueNames("Cabinet_OnOff");
        container.setMessageListener(RbMQReceiverHand);
        return container;
    }
}

RbTestController.java

package com.bw.Test;

import cn.hutool.extra.spring.SpringUtil;
import org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer;
import org.springframework.web.bind.annotation.*;

/**
 * @author ...
 * @version 1.0
 * @date 2020/12/30 17:59
 * @Email [e-mail]
 * @DESC：
 */
@RestController
@RequestMapping("/test")
public class RbTestController {
    @PostMapping
    public String addQueue(@RequestParam String queueNmae) {
        SimpleMessageListenerContainer container = SpringUtil.getBean("messageListenerContainer");
        container.addQueueNames(queueNmae);
        return "添加" + queueNmae + " ok";
    }

    @DeleteMapping
    public String delQueue(@RequestParam String queueNmae) {
        SimpleMessageListenerContainer container = SpringUtil.getBean("messageListenerContainerTwo");
        container.removeQueueNames(queueNmae);
        return "删除 " + queueNmae + " ok";
    }
}

到此结束，就算完成了。

我这里用getBean好处是可扩展
