SpringBoot中整合RabbitMQ（测试+部署上线 最完整）

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 RabbitMQConfig {
 
    private static final String TOPIC_EXCHANGE = "topicExchange";
    private static final String QUEUE_NAME = "queueName";
 
    @Bean
    Queue queue() {
        return new Queue(QUEUE_NAME, true);
    }
 
    @Bean
    TopicExchange exchange() {
        return new TopicExchange(TOPIC_EXCHANGE);
    }
 
    @Bean
    Binding binding(Queue queue, TopicExchange exchange) {
        return BindingBuilder.bind(queue).to(exchange).with("routingKey");
    }
 
    @Bean
    SimpleMessageListenerContainer container(ConnectionFactory connectionFactory,
                                            MessageListenerAdapter listenerAdapter) {
        SimpleMessageListenerContainer container = new SimpleMessageListenerContainer();
        container.setConnectionFactory(connectionFactory);
        container.setQueueNames(QUEUE_NAME);
        container.setMessageListener(listenerAdapter);
        return container;
    }
 
    @Bean
    MessageListenerAdapter listenerAdapter(RabbitMQListener receiver) {
        return new MessageListenerAdapter(receiver, "handleMessage");
    }
}
 
public class RabbitMQListener {
    public void handleMessage(String message) {
        // 处理接收到的消息
    }
}

这个代码示例展示了如何在Spring Boot应用程序中配置和连接RabbitMQ，创建交换器、队列并将它们绑定在一起。同时，它还配置了一个监听器容器来监听指定队列的消息，并将接收到的消息委托给一个处理器（RabbitMQListener）进行处理。这个例子涵盖了RabbitMQ在Spring Boot中的基本使用，并且是在生产环境中部署RabbitMQ的一个很好的实践。
