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;@Configurationpublic class ProducerConfiguration {    // 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 final String helloWorldQueueName = "spring-queue-async";    // 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rabbitTemplate 消息模板类    @Bean    public RabbitTemplate rabbitTemplate() {        RabbitTemplate template = new RabbitTemplate(connectionFactory());        template.setRoutingKey(this.helloWorldQueueName);        return template;    }    //创建一个调度    @Bean    public ScheduledProducer scheduledProducer() {        return new ScheduledProducer();    }    @Bean    public BeanPostProcessor postProcessor() {        return new ScheduledAnnotationBeanPostProcessor();    }    static class ScheduledProducer {        @Autowired        private volatile RabbitTemplate rabbitTemplate;        //自增整数        private final AtomicInteger counter = new AtomicInteger();        /**         * 每3秒发送一条消息         *         * Spring3中加强了注解的使用，其中计划任务也得到了增强，现在创建一个计划任务只需要两步就完成了：         创建一个Java类，添加一个无参无返回值的方法，在方法上用@Scheduled注解修饰一下；         在Spring配置文件中添加三个<task:**** />节点；         参考：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;@Configurationpublic class ConsumerConfiguration {    // 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-async";    // 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 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。
