普通生产者

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

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

public class MyProcuder {
    public static void main(String[] args) throws IOException, TimeoutException {
        ConnectionFactory connectionFactory = new ConnectionFactory();
        connectionFactory.setHost("192.168.205.10");
        connectionFactory.setPort(5672);
        connectionFactory.setUsername("admin");
        connectionFactory.setVirtualHost("/");
        connectionFactory.setPassword("ai123");

        Connection connection = connectionFactory.newConnection();
        Channel channel = connection.createChannel();
        String msg = "Hello My RabbitMQ! t = "+(new Date().toString());
        channel.basicPublish("", "test001", null, msg.getBytes());
        channel.close();
        connection.close();
    }
}

普通消费者

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

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

public class MyConsumer {

    public static void main(String[] args) throws IOException, TimeoutException, InterruptedException {
        ConnectionFactory connectionFactory = new ConnectionFactory();
        connectionFactory.setHost("192.168.205.10");
        connectionFactory.setPort(5672);
        connectionFactory.setUsername("admin");
        connectionFactory.setVirtualHost("/");
        connectionFactory.setPassword("ai123");

        Connection connection = connectionFactory.newConnection();
        Channel channel = connection.createChannel();

        String queueName = "test001";
        channel.queueDeclare(queueName, true, false, false, null);

        QueueingConsumer queueingConsumer = new QueueingConsumer(channel);
        channel.basicConsume(queueName, true, queueingConsumer);

        while(true){
            //7 获取消息
            QueueingConsumer.Delivery delivery = queueingConsumer.nextDelivery();
            String msg = new String(delivery.getBody());
            System.err.println("消费端: " + msg);
            //Envelope envelope = delivery.getEnvelope();
        }

    }
}
