rabbitMq完整通信（一）---producer

 

application.properties：

server.port=8080
spring.application.name=producer
spring.rabbitmq.host=127.0.0.1
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest

最后是pom

 

先创建两个队列：

package com..direct;

import org.springframework.amqp.core.Queue;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
//配置类，随系统启动时，创建两个队列， 用来接收发送过来的数据
@Configuration
public class DirectConf {
     @Bean
     public Queue queue() {
//          System.out.println("系统启动时：创建一个queue的队列到rabbitMQ");
          return new Queue("queue");
     }
     @Bean
     public Queue queueObject() {
//          System.out.println("系统启动时：创建一个queueObject的队列到rabbitMQ");
          return new Queue("queueObject");
     }
}

 

创建队列和交换器，并进行绑定：

package com..topic;

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;
//配置类，随系统启动时，根据需求创建交换器和队列， 用来接收服务端发送过来的数据
@Configuration
public class TopicConf {

        //系统启动时：创建一个message的队列到rabbitMQ
        @Bean(name="message")
        public Queue queueMessage() {
            System.out.println("系统启动时：创建一个topic.order的队列到rabbitMQ");
            return new Queue("topic.order");
        }

        //系统启动时：创建一个exchange的交换器到rabbitMQ
        @Bean
        public TopicExchange exchange() {
            return new TopicExchange("exchange");
        }
        //系统启动时：将exchange的交换器与队列绑定
        @Bean
        Binding bindingExchangeMessage(@Qualifier("message") Queue queueMessage, TopicExchange exchange) {
            System.out.println("系统启动时：将exchange的交换器与topic.order队列绑定");
            return BindingBuilder.bind(queueMessage).to(exchange).with("topic.order");
        }

}

 

定义队列发送的方法：

package com..sender;

import java.util.Map;
import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
public class RabbitSender {
    //注入AmqpTemplate
    @Autowired
    private AmqpTemplate template;
    //由AmqpTemplate将数据发送到指定的队列
    public void send(String queueName,String orderId) {
        System.out.println("由AmqpTemplate将数据发送到指定的队列");
        template.convertAndSend(queueName, orderId);
    }
    //由AmqpTemplate将数据发送到指定的队列，主要用于发送对象
    public void sendObject(String queueName,Map user) {
        System.out.println("由AmqpTemplate将数据发送到指定的队列，主要用于发送对象");
        template.convertAndSend(queueName,user);
    }
    //由AmqpTemplate将数据发送到交换机和队列
    public void sendTopic(String exchange, String queueName, String orderId) {
        System.out.println(Thread.currentThread().getName()+":  进入sendTopic方法");
        System.out.println("%%%由AmqpTemplate将数据发送到交换机"+exchange+" 和队列 "+queueName);
        template.convertAndSend(exchange,queueName,orderId);
    }
}

 

RabbitListener监听服务端发送到队列的数据：

package com.wondersgroup.receive;

import java.util.Map;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

@Component
public class OrderInfoReceive {
    //接收从topic.orderReceive队列的数据（主要存放了服务端订单查询的结果）
    @RabbitListener(queues="topic.orderReceive")    
    public void process1(String orderInfo) {    //用User作为参数
        System.out.println("监听%%%====topic.orderReceive  队列取到的  orderInfo ：========:"+orderInfo);
    }    
}
