生产者项目配置 application.properties

#rabbitmq相关配置
spring.rabbitmq.host=127.0.0.1
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
#消息发送到交换机确认机制,是否确认回调
spring.rabbitmq.publisher-confirms=true 

我们需要配置队列Queue,再配置交换机(Exchange),再把队列按照相应的规则绑定到交换机上:

package com.mr.config;

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.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Controller;

/**
 *
 */
@Configuration
public class SendConfig {

    @Bean(name="message")
    public Queue queueMessage() {
        return new Queue("topic.message");
    }

    @Bean(name="messages")
    public Queue queueMessages() {
        return new Queue("topic.messages");
    }

    @Bean
    public TopicExchange exchange() {
        return new TopicExchange("exchange");
    }

    @Bean
    Binding bindingExchangeMessage(@Qualifier("message") Queue queueMessage, TopicExchange exchange) {
        return BindingBuilder.bind(queueMessage).to(exchange).with("topic.message");
    }

    @Bean
    Binding bindingExchangeMessages(@Qualifier("messages") Queue queueMessages, TopicExchange exchange) {
        return BindingBuilder.bind(queueMessages).to(exchange).with("topic.#");//*表示一个词,#表示零个或多个词
    }

}

测试发送消息

 @RequestMapping("test")
    public String send(){
      rabbitTemplate.convertAndSend("exchange","topic.message","wswsws~");
        return"success";
    }

消费者项目 配置同上

配置如下 接受消息

package com.mr.consumer;

import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

/**
 * 
 */
@Component
public class Consumer  {

    //    @RabbitListener(queues="queue")    //监听器监听指定的Queue
//    public void processC(String str) {
//        System.out.println("Receive:"+str);
//    }

    @RabbitListener(queues="topic.message")    //监听器监听指定的Queue
    public void process1(String str) {
        System.out.println("message:"+str);
    }
    @RabbitListener(queues="topic.messages")    //监听器监听指定的Queue
    public void process2(String str) {
        System.out.println("messages:"+str);
    }
}

启动生产者项目和消费者项目

测试完成
