写在前面的话

系列教程都是从网络上收集和本人的理解所编辑而成，仅供广大爱好者学习所用，请尊重本人的劳动成果。欢迎评论指正和转帖！（请保留连接谢谢！）

一、项目结构

二、POM.XML

三、Producer.java

package com.rabbitmq;

import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;

public class Producer {
    public static void main(String[] args) {
        ApplicationContext context = new AnnotationConfigApplicationContext(AnnotationConfiguration.class);
        AmqpTemplate amqpTemplate = context.getBean(AmqpTemplate.class);
        amqpTemplate.convertAndSend("Hello World");
        System.out.println("Sent: Hello World");
    }
}

四、Consumer.java

package com.rabbitmq;


import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;

public class Consumer {
    public static void main(String[] args) {
        ApplicationContext context = new AnnotationConfigApplicationContext(AnnotationConfiguration.class);
        AmqpTemplate amqpTemplate = context.getBean(AmqpTemplate.class);
        System.out.println("Received: " + amqpTemplate.receiveAndConvert());
    }
}

五、AnnotationConfiguration.java

package com.rabbitmq;


import org.springframework.amqp.core.AmqpAdmin;
import org.springframework.amqp.core.Queue;
import org.springframework.amqp.rabbit.connection.CachingConnectionFactory;
import org.springframework.amqp.rabbit.connection.ConnectionFactory;
import org.springframework.amqp.rabbit.core.RabbitAdmin;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import com.rabbitmq.client.AMQP;

@Configuration
public class AnnotationConfiguration {

    //指定队列名称 routingkey的名称默认为Queue的名称，使用Exchange类型为DirectExchange
    protected String springQueueDemo = "spring-queue-demo";

    //创建链接
    @Bean
    public ConnectionFactory connectionFactory() {
        CachingConnectionFactory connectionFactory = new CachingConnectionFactory("192.168.0.117");
        connectionFactory.setUsername("admin");
        connectionFactory.setPassword("admin");
        connectionFactory.setPort(AMQP.PROTOCOL.PORT);
        return connectionFactory;
    }

    //创建rabbitAdmin 代理类
    @Bean
    public AmqpAdmin amqpAdmin() {
        return new RabbitAdmin(connectionFactory());
    }

    //创建rabbitTemplate 消息模板类
    @Bean
    public RabbitTemplate rabbitTemplate() {
        RabbitTemplate template = new RabbitTemplate(connectionFactory());
        //The routing key is set to the name of the queue by the broker for the default exchange.
        template.setRoutingKey(this.springQueueDemo);
        //Where we will synchronously receive messages from
        template.setQueue(this.springQueueDemo);
        return template;
    }

    //
    // Every queue is bound to the default direct exchange
    public Queue helloWorldQueue() {
        return new Queue(this.springQueueDemo);
    }

    /*
    @Bean
    public Binding binding() {
        return declare(new Binding(helloWorldQueue(), defaultDirectExchange()));
    }*/

    /*
    @Bean
    public TopicExchange helloExchange() {
        return declare(new TopicExchange("hello.world.exchange"));
    }*/

    /*
    public Queue declareUniqueQueue(String namePrefix) {
        Queue queue = new Queue(namePrefix + "-" + UUID.randomUUID());
        rabbitAdminTemplate().declareQueue(queue);
        return queue;
    }

    // if the default exchange isn't configured to your liking....
    @Bean Binding declareP2PBinding(Queue queue, DirectExchange exchange) {
        return declare(new Binding(queue, exchange, queue.getName()));
    }

    @Bean Binding declarePubSubBinding(String queuePrefix, FanoutExchange exchange) {
        return declare(new Binding(declareUniqueQueue(queuePrefix), exchange));
    }

    @Bean Binding declarePubSubBinding(UniqueQueue uniqueQueue, TopicExchange exchange) {
        return declare(new Binding(uniqueQueue, exchange));
    }

    @Bean Binding declarePubSubBinding(String queuePrefix, TopicExchange exchange, String routingKey) {
        return declare(new Binding(declareUniqueQueue(queuePrefix), exchange, routingKey));
    }*/

}

The worldi is like mirror：Frown at itand it frowns at you;smile,and it smiles too.

世界犹如一面镜子：朝它皱眉它就朝你皱眉，朝它微笑它就朝你微笑。
