第六章----基于Java的RabbitMQ发送、消费消息

本系列主要讲基于SpringBoot的RabbitMQ消息队列，基于Java的只做简单记录。

1. 生产者

• 创建连接工厂-->设置参数-->创建连接-->创建通道-->创建交换器-->发送消息-->关闭通道-->关闭连接

package com.fzb.rabbitmq.producer;
import java.io.IOException;
import java.util.concurrent.TimeoutException;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;

public class MQProducerJ {

    public static void main(String[] args) throws IOException, TimeoutException {
        //创建连接工厂
        ConnectionFactory factory = new ConnectionFactory();

        //设置RabbitMQ相关信息
        factory.setHost("192.168.89.168");
        factory.setUsername("fzb");
        factory.setPassword("fzb2019");
        factory.setPort(5672);
        factory.setVirtualHost("fzb_host");

        //创建一个新的连接
        Connection connection = factory.newConnection();

        //创建一个通道
        Channel channel = connection.createChannel();

        //创建一个交换器 默认direct
        channel.exchangeDeclare("direct.java.exchange","direct",true);

        //发送消息到队列中
        String message = "这是java代码：Hello RabbitMQ.";
        channel.basicPublish("direct.java.exchange", "HelloJava", null, message.getBytes("UTF-8"));

        //关闭通道和连接
        channel.close();
        //关闭连接
        connection.close();
    }
}

2. 消费者

• 创建连接工厂-->设置参数-->创建连接-->创建通道-->创建交换器-->创建队列-->创建绑定关系-->消费消息-->关闭通道-->关闭连接

package com.fzb.rabbitmq.consumer;
import java.io.IOException;
import java.util.concurrent.TimeoutException;

import com.rabbitmq.client.*;

public class MQConsumerJ {

    public static void main(String[] args) throws IOException, TimeoutException, InterruptedException {
        // 创建连接工厂
        ConnectionFactory factory = new ConnectionFactory();

        //设置RabbitMQ相关信息
        factory.setHost("192.168.89.168");
        factory.setUsername("fzb");
        factory.setPassword("fzb2019");
        factory.setPort(5672);
        factory.setVirtualHost("fzb_host");

        //创建一个新的连接
        Connection connection = factory.newConnection();

        //创建一个通道
        Channel channel = connection.createChannel();
        
         //创建一个交换器 默认direct
        channel.exchangeDeclare("direct.java.exchange","direct",true);

        //创建一个队列
        channel.queueDeclare("direct.java.queue", true, false, false, null);

        //创建绑定关系
        channel.queueBind("direct.java.queue","direct.java.exchange","HelloJava");

        Consumer consumer = new DefaultConsumer(channel){
            @Override
            public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body)
                    throws IOException {
                String message = new String(body, "UTF-8");
                System.out.println( message);
            }
        };
        channel.basicConsume("direct.java.queue", true, consumer);
    }
}
