三、Producer.java

package com.rabbitmq;

import org.springframework.context.annotation.AnnotationConfigApplicationContext;

public class Producer {

    public static void main(String[] args) {
        new AnnotationConfigApplicationContext(ProducerConfiguration.class);
    }
}

四、ProducerConfiguration.java

package com.rabbitmq;

import java.util.concurrent.atomic.AtomicInteger;

import org.springframework.amqp.rabbit.connection.CachingConnectionFactory;
import org.springframework.amqp.rabbit.connection.ConnectionFactory;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.config.BeanPostProcessor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.scheduling.annotation.ScheduledAnnotationBeanPostProcessor;

import com.rabbitmq.client.AMQP;

@Configuration
public class ProducerConfiguration {

    // 指定隊列名稱 routingkey的名稱默認爲Queue的名稱，使用Exchange類型爲DirectExchange
    protected final String helloWorldQueueName = "spring-queue-async";

    // 創建鏈接
    @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;
    }

    // 創建rabbitTemplate 消息模板類
    @Bean
    public RabbitTemplate rabbitTemplate() {
        RabbitTemplate template = new RabbitTemplate(connectionFactory());
        template.setRoutingKey(this.helloWorldQueueName);
        return template;
    }

    //創建一個調度
    @Bean
    public ScheduledProducer scheduledProducer() {
        return new ScheduledProducer();
    }

    @Bean
    public BeanPostProcessor postProcessor() {
        return new ScheduledAnnotationBeanPostProcessor();
    }


    static class ScheduledProducer {

        @Autowired
        private volatile RabbitTemplate rabbitTemplate;

        //自增整數
        private final AtomicInteger counter = new AtomicInteger();
        /**
         * 每3秒發送一條消息
         *
         * Spring3中加強了註解的使用，其中計劃任務也得到了增強，現在創建一個計劃任務只需要兩步就完成了：
         創建一個Java類，添加一個無參無返回值的方法，在方法上用@Scheduled註解修飾一下；
         在Spring配置文件中添加三個<task:**** />節點；
         參考：http://zywang.iteye.com/blog/949123
         */
        @Scheduled(fixedRate = 3000)
        public void sendMessage() {
            rabbitTemplate.convertAndSend("Hello World " + counter.incrementAndGet());
        }
    }
}

五、Consumer.java

package com.rabbitmq;

import org.springframework.context.annotation.AnnotationConfigApplicationContext;

public class Consumer {
    public static void main(String[] args) {
        new AnnotationConfigApplicationContext(ConsumerConfiguration.class);
    }
}

六、ConsumerConfiguration.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.amqp.rabbit.listener.SimpleMessageListenerContainer;
import org.springframework.amqp.rabbit.listener.adapter.MessageListenerAdapter;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import com.rabbitmq.client.AMQP;

@Configuration
public class ConsumerConfiguration {

    // 指定隊列名稱 routingkey的名稱默認爲Queue的名稱，使用Exchange類型爲DirectExchange
    protected String springQueueDemo = "spring-queue-async";

    // 創建鏈接
    @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;
    }

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

    // 創建rabbitTemplate 消息模板類
    @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 SimpleMessageListenerContainer listenerContainer() {
        SimpleMessageListenerContainer container = new SimpleMessageListenerContainer();
        container.setConnectionFactory(connectionFactory());
        container.setQueueNames(this.springQueueDemo);
        container.setMessageListener(new MessageListenerAdapter(
                new ReceiveMsgHandler()));
        return container;
    }
}

七、ReceiveMsgHandler.java

package com.rabbitmq;

public class ReceiveMsgHandler {

    public void handleMessage(String text) {
        System.out.println("Received: " + text);
    }
}

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

世界猶如一面鏡子：朝它皺眉它就朝你皺眉，朝它微笑它就朝你微笑。
