生产者(hello_producer.py)

import pika, sys

credentials = pika.PlainCredentials("rabbit", "123456")
conn_params = pika.ConnectionParameters("localhost", credentials = credentials)
conn_broker = pika.BlockingConnection(conn_params)
channel = conn_broker.channel()
channel.exchange_declare("hello-exchange","direct",False,False,False)

msg = sys.argv[1]
msg_props = pika.BasicProperties()
msg_props.content_type = "text/plain"
channel.basic_publish(body=msg,exchange="hello-exchange",properties=msg_props,routing_key="hola")

消费者(TestConsumer.java)

import com.rabbitmq.client.*;

import java.io.IOException;

public class TestConsumer {

    public static void main(String[] args) {

        ConnectionFactory factory = new ConnectionFactory();
        factory.setHost("192.168.100.177");
        factory.setPort(5672);
        factory.setUsername("rabbit");
        factory.setPassword("123456");
        factory.setVirtualHost("/");

        Connection connection = null;
        try {
            connection = factory.newConnection();
            Channel channel = connection.createChannel();

            String exchangeName = "hello-exchange";
            String routingKey = "hola";
            String queueName = "queueOne";
            channel.exchangeDeclare(exchangeName,"direct");
            channel.queueDeclare(queueName,false,false,false,null);
            channel.queueBind(queueName,exchangeName,routingKey);

            Consumer consumer = new DefaultConsumer(channel){
                @Override
                public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body) throws IOException {
                    //消费消费
                    String msg = new String(body,"utf-8");
                    System.out.println("consume msg: "+msg);
                    try {
                        TimeUnit.MILLISECONDS.sleep((long) (Math.random()*500));
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                    //手动消息确认
                    getChannel().basicAck(envelope.getDeliveryTag(),false);
                }
            };

            //调用消费消息
            channel.basicConsume(queueName,false,"queueOne", consumer);
        } catch (IOException e) {
            e.printStackTrace();
        } catch (TimeoutException e) {
            e.printStackTrace();
        }
    }
