Spring+RabbitMQ的结合使用

1:创建一个Maven工程,pom.xml文件如下:

2:配置文件如下:

  log4j.properties:

log4j.rootLogger=debug,Console,Stdout

3:创建消费者和生产者:

  Proceducer.java :

package com.liu.rabbitmq;

import javax.annotation.Resource;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.amqp.AmqpException;
import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.core.MessagePostProcessor;
import org.springframework.amqp.core.MessageProperties;
import org.springframework.stereotype.Service;

/**
 * 功能概要:消息产生,提交到队列中去
 * 
 * @author liucc
 * @since  2016年12月1日 
 */
@Service
public class Proceducer  {

    private Logger logger = LoggerFactory.getLogger(Proceducer.class);

    @Resource
    private AmqpTemplate amqpTemplate;

    public void sendMessage(Object message){
      //发送消息到消息队列服务器中,并得到回馈内容
      Object object=amqpTemplate.convertSendAndReceive("queueTest",message,new MessagePostProcessor() {
            @Override
            public Message postProcessMessage(Message message) throws AmqpException {
                MessageProperties props = message.getMessageProperties();
                //把版本加入消息头中
                props.setHeader("header", "1.0.0");
                props.setExpiration(String.valueOf(30000));
                logger.debug("设置RPC消息的TTL为{}", 30000);
                return message;
            }
        });
      System.out.println(object);
    }
}

  Consumer.java:

package com.liu.rabbitmq;

import java.io.ByteArrayInputStream;
import java.io.ObjectInputStream;

import javax.annotation.Resource;

import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.core.MessageListener;
import org.springframework.amqp.core.MessageProperties;
import org.springframework.amqp.support.converter.MessageConverter;
import org.springframework.amqp.support.converter.SimpleMessageConverter;

/**
 * 功能概要:消费接收
 * 
 * @author liucc
 * @since  2016年12月1日 
 */
public class Consumer implements MessageListener {
    //private Logger logger = LoggerFactory.getLogger(Consumer.class);
    @Resource
    private AmqpTemplate amqpTemplate;
    
    @Override
    public void onMessage(Message message) {
        //logger.info("receive message:{}",message);
        try {
            //将字节流对象转换成Java对象
            Person person=(Person) new ObjectInputStream(new ByteArrayInputStream(message.getBody())).readObject();
            System.out.println("年龄:"+person.getAge());
        } catch (Exception e) {
            e.printStackTrace();
        }
        String replyTo = message.getMessageProperties().getReplyTo();
        MessageConverter messageConverter=new SimpleMessageConverter();
        
        MessageProperties messageProperties = new MessageProperties();
        messageProperties.getHeaders().putAll(message.getMessageProperties().getHeaders());
        
        String response=new String("收到返回消息");
        //将Java对象转成Message对象,并作为返回的内容,回送给生产者
        Message message2=messageConverter.toMessage(response, messageProperties);
        amqpTemplate.send(replyTo, message2);
        
        
    }
}

4:测试

  创建实体类:Person.java

  

package com.liu.rabbitmq;

import java.io.Serializable;

public class Person implements Serializable {
    
    private static final long serialVersionUID = 1L;
    private String name;
    private int age;
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
    public Person(String name, int age) {
        super();
        this.name = name;
        this.age = age;
    }
    
}

  RAbbitmqTest.java:

package com.liu.rabbitmq;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class RabbitmqTest {
    
    public static void main(String[] args) {
        ClassPathXmlApplicationContext context=new ClassPathXmlApplicationContext("application-context.xml");
        Proceducer proceducer=(Proceducer) context.getBean("proceducer") ; 
        Person person=new Person("liucc",22);
        System.out.println(person);
        proceducer.sendMessage(person);        
        
    }
}

注:本demo主要实现了rabbitMQ集合Spring框架的基本使用,生产者向消息队列服务器发送消息,消费者接收消息,并经过简单的处理,将消息返回给生产者,完成一个基本的通信过程。消息的传输对象可以是任何对象,在内部传输时都会别装换成RabbitMQ特有的对象Message(类似报文对象),消息的主体在Message的body部分。
