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);
}
