rabbitMQ学习（七）

反馈模式

在消费端接收到消息后，会反馈给服务器信息。

连接代码：

import java.io.IOException;

import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;

public class GetChannel {
	 private static Connection connection=null;
	 private static Channel channel=null;
	public static Channel getCh() throws IOException{
		 ConnectionFactory factory = new ConnectionFactory();
		    factory.setHost("localhost");
		     connection = factory.newConnection();
		     channel = connection.createChannel();
		    return channel;
	}

	public static void close() throws IOException{
		if(channel!=null){
			channel.close();
		}
		if(connection!=null){
			connection.close();
		}
	}

}

　　发送消息端：

import com.jiacl.finance.rabbitmq.exchange.GetChannel;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.MessageProperties;

public class Send {
    final static String queueName="queuetwo";
    public static void  main(String args[]) throws Exception{
    	Channel channel = GetChannel.getCh();
        channel.queueDeclare(queueName, true,false,false,null);
        channel.basicPublish("",queueName,MessageProperties.PERSISTENT_TEXT_PLAIN,"fuck".getBytes());
        GetChannel.close();
    }
}

　　接收消息端：

import com.jiacl.finance.rabbitmq.exchange.GetChannel;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.QueueingConsumer;

public class recvier {
    final static String queueName="queuetwo";

    public static void main(String[] args)throws Exception {
    	Channel channel = GetChannel.getCh();
        channel.queueDeclare(queueName, true, false, false, null);
        channel.basicQos(1);
        QueueingConsumer consumer=new QueueingConsumer(channel);
        channel.basicConsume(queueName,false,consumer);
        while (true){
           QueueingConsumer.Delivery delivery=consumer.nextDelivery();
            String message = new String(delivery.getBody());
            System.out.println(message);
            channel.basicAck(delivery.getEnvelope().getDeliveryTag(),true);
        }

    }

}
