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http://ip:15672/ 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：
