> # RabbitMQ：RabbitMQ+Sping整合发送异步消息 #

### （一） XML配置方式： ###

** 1.【配置文件】：**

**application-async.xml **

#============== rabbitmq config ====================
    rabbit.hosts=127.0.0.1
    rabbit.username=
    rabbit.password=
    rabbit.virtualHost=/
    rabbit.queue=spring-queue-async
    rabbit.routingKey=spring-queue-async

**消费者配置XML ：applicationContext-rabbitmq-async-receive.xml**

<?xml version="1.0" encoding="UTF-8"?>

        </bean>
        
    
    </beans>

**生产者XML配置：applicationContext-rabbitmq-async-send.xml： **

**接收消息启动类：Receive.java  启动接收消息，再发送消息**

package com.caox.rabbitmq.demo._09_spring_rabbitmq_async_xml;
    
    /**
     * Created by nazi on 2018/7/27.
     */
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    
    public class Receive {
    
        public static void main(String[] args) {
            new ClassPathXmlApplicationContext("applicationContext-rabbitmq-async-receive.xml");
        }
    }

**生产者发送消息类：Send.java **

package com.caox.rabbitmq.demo._09_spring_rabbitmq_async_xml;
    
    import org.springframework.amqp.core.AmqpTemplate;
    import org.springframework.amqp.rabbit.core.RabbitTemplate;
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    /**
     * Created by nazi on 2018/7/27.
     */
    public class Send {
    
        public static void main(String[] args) throws InterruptedException {
            ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext-rabbitmq-async-send.xml");
            AmqpTemplate amqpTemplate = context.getBean(RabbitTemplate.class);
            for(int i=0;i<1000;i++){
                amqpTemplate.convertAndSend("test spring async=>"+i);
                Thread.sleep(3000);
            }
        }
    }

**处理消息类：ReceiveMsgHandler.java **

package com.caox.rabbitmq.demo._09_spring_rabbitmq_async_xml;
    
    /**
     * Created by nazi on 2018/7/27.
     */
    public class ReceiveMsgHandler {
        public void handleMessage(String text) {
            System.out.println("Received: " + text);
        }
    }

### **（二） Annotation 注解方式： ** ###

**1.【生产者配置和启动类】：ProducerConfiguration.java 和 Producer.java**

package com.caox.rabbitmq.demo._10_spring_rabbitmq_async_annotation;
    
    import org.springframework.context.annotation.Configuration;
    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.scheduling.annotation.Scheduled;
    import org.springframework.scheduling.annotation.ScheduledAnnotationBeanPostProcessor;
    
    import com.rabbitmq.client.AMQP;
    /**
     * Created by nazi on 2018/7/27.
     */
    @Configuration
    public 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("127.0.0.1");
            connectionFactory.setUsername("caoxia");
            connectionFactory.setPassword("caoxia123456");
            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());
            }
        }
    
    }

package com.caox.rabbitmq.demo._10_spring_rabbitmq_async_annotation;
    
    /**
     * Created by nazi on 2018/7/27.
     */
    import org.springframework.context.annotation.AnnotationConfigApplicationContext;
    
    public class Producer {
    
        public static void main(String[] args) {
            new AnnotationConfigApplicationContext(ProducerConfiguration.class);
        }
    }

**2.【消费者配置和启动类】：** **ConsumerConfiguration.java和Consumer.java**

package com.caox.rabbitmq.demo._10_spring_rabbitmq_async_annotation;
    
    import org.springframework.amqp.core.AmqpAdmin;
    import org.springframework.amqp.core.Queue;
    import org.springframework.amqp.rabbit.connection.CachingConnectionFactory;

    import com.rabbitmq.client.AMQP;
    /**
     * Created by nazi on 2018/7/27.
     */
    
    @Configuration
    public 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(
                    "127.0.0.1");
            connectionFactory.setUsername("caoxia");
            connectionFactory.setPassword("caoxia123456");
            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;
        }
    
    }

package com.caox.rabbitmq.demo._10_spring_rabbitmq_async_annotation;
    
    /**
     * Created by nazi on 2018/7/27.
     */
     import org.springframework.context.annotation.AnnotationConfigApplicationContext;
    
    public class Consumer {
        public static void main(String[] args) {
            new AnnotationConfigApplicationContext(ConsumerConfiguration.class);
        }
    }

**3.【接收消息处理类 】：ReceiveMsgHandler.java**

package com.caox.rabbitmq.demo._10_spring_rabbitmq_async_annotation;
    
    /**
     * Created by nazi on 2018/7/27.
     */
    
    public class ReceiveMsgHandler {
    
        public void handleMessage(String text) {
            System.out.println("Received: " + text);
        }
    }
