一、Spring整合RabbitMQ

1. 搭建生产者工程

1.1 添加依赖

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>5.1.7.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.amqp</groupId>
        <artifactId>spring-rabbit</artifactId>
        <version>2.1.8.RELEASE</version>
    </dependency>
    <dependency>

2.4 测试

二、Springboot整合RabbitMQ

2.1 创建生产者工程

2.1.1 添加依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.zjl</groupId>
    <artifactId>spring-boot-rabbitmq-producer</artifactId>
    <version>1.0-SNAPSHOT</version>

    <parent>
        <artifactId>spring-boot-starter-parent</artifactId>
        <groupId>org.springframework.boot</groupId>
        <version>2.1.6.RELEASE</version>
    </parent>

    <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>
</project>

2.1.2 启动类

@SpringBootApplication
public class ProducerApplication {
    public static void main(String[] args) {
        SpringApplication.run(ProducerApplication.class);
    }
}

2.1.3 配置RabbitMQ

2.1.3.1 配置文件

创建application.yml，内容如下：

spring:
  rabbitmq:
    host: XXX.XXX.XXX.XXX
    port: 5672
    virtual-host: /admin
    username: admin
    password: admin

2.1.3.2 绑定交换机和队列

创建RabbitMQ队列与交换机绑定的配置类com.zjl.rabbitmq.config.RabbitMQConfig

@Configuration
public class RabbitMQConfig {
    //交换机名称
    public static final String ITEM_TOPIC_EXCHANGE = "springboot_item_topic_exchange";
    //队列名称
    public static final String ITEM_QUEUE = "springboot_item_queue";

    //声明交换机
    @Bean("itemTopicExchange")
    public Exchange topicExchange(){
        return ExchangeBuilder.topicExchange(ITEM_TOPIC_EXCHANGE).durable(true).build();
    }

    //声明队列
    @Bean("itemQueue")
    public Queue itemQueue(){
        return QueueBuilder.durable(ITEM_QUEUE).build();
    }

    //绑定队列和交换机
    @Bean
    public Binding itemQueueExchange(@Qualifier("itemQueue") Queue queue,
                                     @Qualifier("itemTopicExchange") Exchange exchange){
        return BindingBuilder.bind(queue).to(exchange).with("item.#").noargs();
    }

}

2.4.3 测试

@RunWith(SpringRunner.class)
@SpringBootTest
public class ProducerApplicationTest{

    @Autowired
    private RabbitTemplate rabbitTemplate;

    @Test
    public void test(){
        rabbitTemplate.convertAndSend(RabbitMQConfig.ITEM_TOPIC_EXCHANGE, "item.insert", "商品新增，routing key 为item.insert");
        rabbitTemplate.convertAndSend(RabbitMQConfig.ITEM_TOPIC_EXCHANGE, "item.update", "商品修改，routing key 为item.update");
        rabbitTemplate.convertAndSend(RabbitMQConfig.ITEM_TOPIC_EXCHANGE, "item.delete", "商品删除，routing key 为item.delete");
    }

}

2.2 创建消费者工程

2.2.1 添加依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

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

</project>

2.2.2 启动类

@SpringBootApplication
public class ConsumerApplication {
    public static void main(String[] args) {
        SpringApplication.run(ConsumerApplication.class, args);
    }
}

2.2.3 配置RabbitMQ

创建application.yml，内容如下：

spring:
  rabbitmq:
    host: XXX.XXX.XXX.XXX
    port: 5672
    virtual-host: /admin
    username: admin
    password: admin

2.2.4 消息监听处理类

编写消息监听器com.zjl.rabbitmq.listener.MyListener

@Component
public class MyListener {
    /**
     * 监听某个队列的消息
     * @param message 接收到的消息
     */
    @RabbitListener(queues = "springboot_item_queue")
    public void myListener1(String message){
        System.out.println("消费者接收到的消息为：" + message);
    }
}

2.2.5 测试
