RabbitMQ：RabbitMQ+Sping整合发送异步消息

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

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);
    }
}

         *
         * 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)

        // 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() {
