利用RabbitMQ实现生产者和消费者的一个小Demo
不做讲解 直接上代码
import com.rabbitmq.client.Channel; import com.rabbitmq.client.Connection; import com.rabbitmq.client.ConnectionFactory; /** * 单消息队列通道 * Created by wangtf on 2015/11/16. * 生产者 */ public class Producer { private final static String QUEUE_NAME="hello"; public static void main(String[] argv) throws Exception { ConnectionFactory factory = new ConnectionFactory(); factory.setHost("localhost"); 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("UTF-8")); System.out.println(" [x] Sent ‘" + message + "‘"); channel.close(); connection.close(); } }
import com.rabbitmq.client.*; import java.io.IOException; /** * Created by wangtf on 2015/11/16. * 消费者 */ public class Consume { private final static String QUEUE_NAME="hello"; public static void main(String[] argv) throws Exception { ConnectionFactory factory = new ConnectionFactory(); factory.setHost("localhost"); Connection connection = factory.newConnection(); Channel channel = connection.createChannel(); channel.queueDeclare(QUEUE_NAME, false, false, false, null); System.out.println(" [*] Waiting for messages. To exit press CTRL+C"); 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(" [x] Received ‘" + message + "‘"); } }; channel.basicConsume(QUEUE_NAME, true, consumer); } }
