RabbitMQ学习（三）-- Spring boot 集成 RabbitTemplate_springboot rabbittemplate

1，引包

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-amqp</artifactId>
            <version>2.4.0</version>
        </dependency>

2，添加配置

spring:
  rabbitmq:
    addresses: 10.211.55.7
    port: 5672
    username: guest
    password: guest
    virtual-host: /

3，添加RabbitConfig

package com.wayne.core.config;
 
import com.rabbitmq.client.AMQP;
import org.springframework.amqp.core.*;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Component;
 
@Configuration
public class RabbitConfig {
 
    public static final String EXCHANGE_NAME = "boot_topic_exchange";
    public static final String QUEUE_NAME = "boot_queue";
 
    //1，交换机对象
    @Bean("buildExchange")
    public Exchange buildExchange(){
        return ExchangeBuilder.topicExchange(EXCHANGE_NAME).durable(true).build();
    }
 
    //2，队列
    @Bean("buildQueue")
    public Queue buildQueue(){
        return QueueBuilder.durable(QUEUE_NAME).build();
    }
 
    //3，绑定交换机和队列
    @Bean
    public Binding bindQueueExchange(@Qualifier("buildQueue") Queue queue,@Qualifier("buildExchange") Exchange exchange){
        return BindingBuilder.bind(queue).to(exchange).with("boot.#").noargs();
    }
}

4，添加生产者

    @Autowired
    private RabbitTemplate rabbitTemplate;
 
    @PostMapping("/send")
    public void sendMessage(){
        rabbitTemplate.convertAndSend(EXCHANGE_NAME,"boot.hahah","hello spring boot rabbitMQ!~~~~~~~");
    }

5，添加消费者

 
    @RabbitListener(queues = QUEUE_NAME)
    public void rabbitMQConsumerListener(Message message){
        log.info("当前队列信息为"+message);
    }

6，测试
