springboot整合rabbitmq

生产者整合

　　引入依赖：

<!--父工程-->
<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.8.RELEASE</version>
</parent>
<!--依赖-->
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-amqp</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
    </dependency>
</dependencies>

　　然后我们可以写一个config类，来定义交换机和队列，以及他们的绑定关系

package com.layton.rabbitmq.config;

import org.springframework.amqp.core.*;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class RabbitMQConfig {

    public static final String Exchange_NAME = "boot_topic_exchange";
    public static final String Queue_NAME = "boot_topic_queue";

    //1.交换机
    @Bean("bootExchange")
    public Exchange bootExchange(){
        return ExchangeBuilder.topicExchange(Exchange_NAME).durable(true).build();
    }

    //2.队列
    @Bean("bootQueue")
    public Queue bootQueue(){
        return QueueBuilder.durable(Queue_NAME).build();
    }

    //3.队列和交换机绑定的关系Binding
    @Bean
    public Binding bindQueueExchange(@Qualifier("bootQueue") Queue queue,@Qualifier("bootExchange") Exchange exchange){
        return BindingBuilder.bind(queue).to(exchange).with("boot.#").noargs();
    }
}

　　这样绑定完了之后，我们可以在生产端想发消息的地方注入RabbitTemplate工具类，然后完成方法的发送

package com.layton.test;

import com.layton.rabbitmq.config.RabbitMQConfig;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@SpringBootTest
@RunWith(SpringRunner.class)
public class ProducerTest {
    //1注入RabbitTemplate类
    @Autowired
    private RabbitTemplate rabbitTemplate;

    @Test
    public void testSend(){
        rabbitTemplate.convertAndSend(RabbitMQConfig.Exchange_NAME,"boot.haha","boot mq hello~");
    }
}

消费端整合

　　同样的引入依赖：

<!--父工程-->
<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.8.RELEASE</version>
</parent>
<!--依赖-->
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-amqp</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
    </dependency>
</dependencies>

　　然后定义消费端的监听器，用于监听队列的信息，需要注意的是RabbitListener注解中的queues属性就是指定队列名，同时需要注意这个类要加Component注解，让spring进行管理

package com.layton.mq;

import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

@Component
public class RabbitMQListener {
    @RabbitListener(queues = "boot_topic_queue")
    public void ListenerQueue(Message message){
        System.out.println(message);
    }
}
