SpringBoot快速整合RabbitMq小案例(使用步骤)

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

spring:
  rabbitmq:
    host: localhost
    port: 5672
    virtual-host: {你的虚拟主机}
    username: {你的用户名}
    password: {你的密码}

@Autowired
private RabbitTemplate rabbitTemplate;
public void sendMessage(String message) {
    rabbitTemplate.convertAndSend("exchangeName", "routingKey", message);
}

@RabbitListener(queues = "queueName")
public void receiveMessage(String message) {
    // 处理接收到的消息
    System.out.println("Received message: " + message);
}

// 交换机名称
    public static final String ITEM_TOPIC_EXCHANGE = "item_topic_exchange";
    // 队列名称
    public static final String ITEM_QUEUE = "item_queue";
    //声明交换机
    @Bean
    public Exchange exchange(){
        return ExchangeBuilder.topicExchange(ITEM_TOPIC_EXCHANGE).durable(true).build();
    }
    //声明队列
    @Bean
    public Queue queue(){
        return QueueBuilder.durable(ITEM_QUEUE).build();
    }
    //队列绑定到交换机
    @Bean
    public Binding binding(Queue queue,Exchange exchange){
        return BindingBuilder.bind(queue).to(exchange).with("item.#").noargs();
    }

    @Autowired
    RabbitTemplate rabbitTemplate;
@Test
    public void testSendMessage(){
        rabbitTemplate.convertAndSend(RabbitmqConfig.ITEM_TOPIC_EXCHANGE, "item.insert", "新增商品的消息~~");
        System.out.println("消息发送成功");
    }
