三、Springboot2.X整合RabbitMQ

Springboot2.X整合RabbitMQ

1.新建springboot工程并选择添加web组件

2.pom文件 配置

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.4.5</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <groupId>cn.net.mqwithspboot</groupId>
    <artifactId>rabbitmqdemo</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>rabbitmqdemo</name>
    <description>Demo project for Spring Boot</description>

    <properties>
        <java.version>1.8</java.version>
    </properties>

    <dependencies>

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

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

    </dependencies>

3.配置文件

spring:
  rabbitmq:
    host: 20.18.24.143
    port: 5672
    virtual-host: devTest
    username: admin
    password: 123456

4.RabbitMQConfig配置类

@Configuration
public class RabbitMQConfig {

    public static final String EXXCHANGE_NAME = "order_exchange";

    public static final String QUEUE = "order_queue";


    /**
     * 交换机
     * @return
     */
    @Bean
    public Exchange orderExchange(){
        return ExchangeBuilder.topicExchange(EXXCHANGE_NAME).durable(true).build();
    }

    /**
     * 队列
     * @return
     */
    @Bean
    public Queue orderQueue(){
        return QueueBuilder.durable(QUEUE).build();
    }

    /**
     * 交换机和队列绑定关系
     */
    @Bean
    public Binding orderBinding(Queue queue,Exchange exchange ){
        return BindingBuilder.bind(queue).to(exchange).with("order.#").noargs();
    }

}

5.消费者代码（一个监听指定队列的服务）

@Component
@RabbitListener(queues = "order_queue")
public class OrderMQListener {

    @RabbitHandler
    public void messageHandler(String body, Message message, Channel channel) throws IOException {
        long msgTag = message.getMessageProperties().getDeliveryTag();
        System.out.println("msgTag="+msgTag);
        System.out.println("message="+message.toString());
        System.out.println("body="+body);

    }

}

6.生产者测试代码

 @Test
 void testSend() {
     template.convertAndSend(RabbitMQConfig.EXXCHANGE_NAME,"order.new","新订单");
 }
