RabbitMQ工作模式

提供者：RabbitProvider

package com.example.RabbitWork;

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

import java.io.IOException;
import java.util.concurrent.TimeoutException;

public class RabbitProvider {
    public static void main(String[] args) throws IOException, TimeoutException {

        Connection connection = RabbitMQUtils.getConnection();
        Channel channel = connection.createChannel();
        channel.queueDeclare("queue",true,false,false,null);
        for (int i = 0; i < 10; i++) {
            String message = "我又来看看" + i;
            channel.basicPublish("","queue",null,message.getBytes());
        }
        channel.close();
        connection.close();
    }
}

        DefaultConsumer defaultConsumer = new DefaultConsumer(channel){
            @Override
            public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body) throws IOException {
                String routingKey = envelope.getRoutingKey();
                String exchange = envelope.getExchange();
                long deliveryTag = envelope.getDeliveryTag();
                String message = new String(body,"UTF-8");
                System.out.println("routingKey:"+routingKey+",exchange:"+exchange+",deliveryTag:"+deliveryTag+",message:"+message);
            }
        };
