发送消息：Send.java
RabbitMqParm.HOST如果把rabbitMq装在本机了，就写“localhost”，本人把rabbitMq搭在阿里云服务器了，所以就是相应的外网ip

import com.rabbitmq.client.Channel; 
import com.rabbitmq.client.Connection; 
import com.rabbitmq.client.ConnectionFactory; 
import com.zheng.model.RabbitMqParm; 
 
public class Send { 
    private final static String QUEUE_NAME = "simple-queue"; 
 
    public static void main(String[] argv) throws java.io.IOException, TimeoutException { 
        ConnectionFactory factory = new ConnectionFactory(); 
        factory.setHost(RabbitMqParm.HOST); 
 
        Connection connection = connection = factory.newConnection(); 
        Channel channel = connection.createChannel(); 
 
        channel.queueDeclare(QUEUE_NAME, false, false, false, null); 
        String message = "Hello world!"; 
        channel.basicPublish("", QUEUE_NAME, null, message.getBytes()); 
        System.out.println("发送的消息：" + message + "'"); 
 
        channel.close(); 
        connection.close(); 
    } 
}

接收消息：Recv.java

import com.rabbitmq.client.*; 
import com.zheng.model.RabbitMqParm; 
import org.slf4j.Logger; 
import org.slf4j.LoggerFactory; 
 
import java.io.IOException; 
import java.util.concurrent.TimeoutException; 
 
public class Recv {
    
    private static final Logger logger = LoggerFactory.getLogger(Recv.class); 
 
    private final static String QUEUE_NAME = "simple-queue"; 
 
    public static void main(String[] argv) throws TimeoutException, IOException { 
 
        ConnectionFactory factory = new ConnectionFactory(); 
        factory.setHost(RabbitMqParm.HOST); 
        Connection connection = factory.newConnection();//建立tcp连接 
        Channel channel = connection.createChannel(); 
 
        channel.queueDeclare(QUEUE_NAME, false, false, false, null); 
 
        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("接收到的消息" + message ); 
            } 
        }; 
        channel.basicConsume(QUEUE_NAME, true, consumer); 
    } 
}

运行Send.java后，到IT虾米网 界面可看到已经创建了一个名为simple-queue的queue

点进去，看到有消息发送过来：

启动Recv.java以后，消息被消费：
