rabbitmq 小案例

1.先导入依赖

	<dependency>
			<groupId>com.rabbitmq</groupId>
			<artifactId>amqp-client</artifactId>
			<version>3.4.1</version>
		</dependency>

2.创建连接类RabbitmqConnect去连接MQ，启动main方法进行测试

package com.techman.baomidou2.web.config.rabbitmq;

import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;

public class RabbitmqConnect {
    
    
    public static Connection getConnection() throws Exception {
    
    
        //定义连接工厂
        ConnectionFactory factory = new ConnectionFactory();
        //设置服务地址
        factory.setHost("localhost");
        //端口
        factory.setPort(5672);
        //设置账号信息，用户名、密码、vhost
        factory.setVirtualHost("/");
        factory.setUsername("guest");
        factory.setPassword("guest");
        // 通过工程获取连接
        Connection connection = factory.newConnection();
        if (connection.isOpen()){
    
    
            System.out.println("连接成功");
        }else{
    
    
            System.out.println("连接失败");
        }
        return connection;
    }

    public static void main(String[] args) {
    
    
        //测试连接
        try {
    
    
            System.out.println(RabbitmqConnect.getConnection());
        } catch (Exception e) {
    
    
            e.printStackTrace();
        }
    }


}

测试结果

3.创建消息生产者类，启动main方法进行测试

package com.techman.baomidou2.web.config.rabbitmq;

import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;

public class Send {
    
    
    private final static String QUEUE_NAME = "bryan01";

    public static void main(String[] argv) throws Exception {
    
    
        // 获取到连接以及mq通道
        Connection connection = RabbitmqConnect.getConnection();
        // 从连接中创建通道
        Channel channel = connection.createChannel();

        // 声明（创建）队列
        channel.queueDeclare(QUEUE_NAME, false, false, false, null);

        // 消息内容
        String message = "Hello World!";
        channel.basicPublish("", QUEUE_NAME, null, message.getBytes());
        System.out.println(" [x] Sent '" + message + "'");
        //关闭通道和连接
        channel.close();
        connection.close();

    }
}

测试结果

4 启动消息接收类，启动main方法进行测试

package com.techman.baomidou2.web.config.rabbitmq;

import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.QueueingConsumer;

public class Recv {
    
    
    private final static String QUEUE_NAME = "bryan01";

    public static void main(String[] argv) throws Exception {
    
    

        // 获取到连接以及mq通道
        Connection connection = RabbitmqConnect.getConnection();
        // 从连接中创建通道
        Channel channel = connection.createChannel();
        // 声明队列
        channel.queueDeclare(QUEUE_NAME, false, false, false, null);

        // 定义队列的消费者
        QueueingConsumer consumer = new QueueingConsumer(channel);

        // 监听队列
        channel.basicConsume(QUEUE_NAME, true, consumer);

        // 获取消息
        while (true) {
    
    
            QueueingConsumer.Delivery delivery = consumer.nextDelivery();
            String message = new String(delivery.getBody());
            System.out.println(" [x] Received '" + message + "'");
        }
    }


}
