Spring Boot异步消息之AMQP讲解及实战

import org.springframework.amqp.core.Binding;
import org.springframework.amqp.core.BindingBuilder;
import org.springframework.amqp.core.Queue;
import org.springframework.amqp.core.TopicExchange;
import org.springframework.amqp.rabbit.connection.ConnectionFactory;
import org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer;
import org.springframework.amqp.rabbit.listener.adapter.MessageListenerAdapter;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
 
@Configuration
public class AsyncRabbitConfiguration {
 
    @Bean
    Queue asyncQueue() {
        return new Queue("async_queue", true);
    }
 
    @Bean
    TopicExchange asyncExchange() {
        return new TopicExchange("async_exchange");
    }
 
    @Bean
    Binding bindingAsyncExchange(Queue asyncQueue, TopicExchange asyncExchange) {
        return BindingBuilder.bind(asyncQueue).to(asyncExchange).with("async.#");
    }
 
    @Bean
    SimpleMessageListenerContainer messageListenerContainer(ConnectionFactory connectionFactory, MessageListenerAdapter listenerAdapter) {
        SimpleMessageListenerContainer container = new SimpleMessageListenerContainer();
        container.setConnectionFactory(connectionFactory);
        container.setQueueNames("async_queue");
        container.setMessageListener(listenerAdapter);
        return container;
    }
 
    @Bean
    MessageListenerAdapter listenerAdapter(AsyncRabbitReceiver receiver) {
        return new MessageListenerAdapter(receiver, "receiveMessage");
    }
}
 
public class AsyncRabbitReceiver {
    public void receiveMessage(String message) {
        // 处理接收到的消息
    }
}

这个代码示例展示了如何在Spring Boot应用中配置和使用RabbitMQ的异步消息队列。首先，我们定义了一个配置类，其中包含了队列、交换器和绑定的定义。然后，我们创建了一个消息监听容器，并指定了适配器来处理接收到的消息。最后，我们定义了一个消息接收者类，其中包含了处理消息的方法。这个例子简单明了地展示了如何在Spring Boot中集成异步消息队列服务RabbitMQ。
