RabbitMQ路由方式实例代码分析

这篇文章主要讲解了“RabbitMQ路由方式实例代码分析”，文中的讲解内容简单清晰，易于学习与理解，下面请大家跟着小编的思路慢慢深入，一起来研究和学习“RabbitMQ路由方式实例代码分析”吧！

SpringBoot RabbitMQ 路由方式

生产者声明三个队列和一个直接交换机，将三个队列绑定到交换机，并设置交换机和队列之间的路由

import com.example.rabbitmq.constant.RabbitConstant;import org.springframework.amqp.core.Binding;import org.springframework.amqp.core.BindingBuilder;import org.springframework.amqp.core.DirectExchange;import org.springframework.amqp.core.Queue;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;@Configurationpublic class RabbitRoutingProvider {    @Bean    public Queue rabbitRoutingFirstQueue() {        return new Queue(RabbitConstant.ROUTING_FIRST_QUEUE_NAME);    }    @Bean    public Queue rabbitRoutingSecondQueue() {        return new Queue(RabbitConstant.ROUTING_SECOND_QUEUE_NAME);    }    @Bean    public Queue rabbitRoutingThirdQueue() {        return new Queue(RabbitConstant.ROUTING_THIRD_QUEUE_NAME);    }    @Bean    public DirectExchange directExchange() {        // Create a direct switch, indicating that the exchange opportunity sends messages to routing_ Queue with identical key        return new DirectExchange(RabbitConstant.ROUTING_EXCHANGE_NAME);    }    @Bean    public Binding routingFirstQueueBindDirectExchange() {        // Bind the direct switch to the queue and set the routing_key is routing_first_queue_routing_key        return BindingBuilder.bind(rabbitRoutingFirstQueue()).to(directExchange()).with(RabbitConstant.ROUTING_FIRST_QUEUE_ROUTING_KEY_NAME);    }    @Bean    public Binding routingSecondQueueBindDirectExchange() {        // Queue 2 binds the direct switch and sets routing_key is routing_second_queue_routing_key        return BindingBuilder.bind(rabbitRoutingSecondQueue()).to(directExchange()).with(RabbitConstant.ROUTING_SECOND_QUEUE_ROUTING_KEY_NAME);    }    @Bean    public Binding routingThirdQueueBindDirectExchange() {        // The queue 3 is bound to the direct switch and the routing is set_ Key is routing_third_queue_routing_key        return BindingBuilder.bind(rabbitRoutingThirdQueue()).to(directExchange()).with(RabbitConstant.ROUTING_THIRD_QUEUE_ROUTING_KEY_NAME);     } }

消费者监听队列并消费

导入 com.example.rabbitmq.constant.RabbitConstant；导入 org.springframework.amqp.rabbit.annotation.RabbitHandler；导入 org.springframework.amqp.rabbit.annotation.RabbitListener；导入 org.springframework.stereotype.Component；@Component public class RabbitRoutingConsumer {     @RabbitListener(queues = RabbitConstant.ROUTING_FIRST_QUEUE_NAME)     @RabbitHandler     public void routingFirstQueueListener(String context) {         System.out.println("rabbit routing queue first receiver:" + context);     }     @RabbitListener(queues = RabbitConstant.ROUTING_SECOND_QUEUE_NAME)     @RabbitHandler     public void routingSecondQueueListener(String context) {        System.out.println("rabbit pubsub 队列第二个接收者：" + context);     }     @RabbitListener(queues = RabbitConstant.ROUTING_THIRD_QUEUE_NAME)     @RabbitHandler     public void routingThirdQueueListener(String context) {         System.out.println("rabbit pubsub 队列第三个接收者：" + context);     } }

单元测试

@Test public void routing() {     // 向第一个队列发送消息    rabbitTemplate.convertAndSend(RabbitConstant.ROUTING_EXCHANGE_NAME, RabbitConstant.ROUTING_FIRST_QUEUE_ROUTING_KEY_NAME, "routing hello"); }
