AMQP--rabbitmq--1

1.基本安装

分为 server + client

server的安装：

1.添加 deb http://www.rabbitmq.com/debian/ testing main 到 /etc/apt/sources.list

2.apt-get update.

3.sudo apt-get install rabbitmq-server

这个步骤会自动启动 rabbitmq-server 服务。

常用命令：

rabbitmqctl -h

rabbitmqctl status

rabbitmqctl stop

rabbitmqctl start_app

客户端安装：

maven:

<groupId>com.rabbitmq</groupId>

<artifactId>amqp-client</artifactId>

</dependency>

或是下载链接：

wget http://www.rabbitmq.com/releases/rabbitmq-java-client/v2.8.4/rabbitmq-java-client-bin-2.8.4.tar.gz

客户端编码---发送者：

package com.jieting.mq.rabbit.send;

import java.io.IOException;

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

public class MessageSend {

    private static final String QUENE_NAME = "hello";

    public static void main(String[] args) throws IOException {

        ConnectionFactory connectionFactory = new ConnectionFactory();
        connectionFactory.setHost("localhost");

        Connection newConnection = connectionFactory.newConnection();
        Channel createChannel = newConnection.createChannel();

        createChannel.queueDeclare(QUENE_NAME, true, false, false, null);
        String message = "hello rabbitmq world!";
        createChannel.basicPublish("", QUENE_NAME, null, message.getBytes());

        System.out.println(" [x] Sent '" + message + "'");

        createChannel.close();
        newConnection.close();

    }
}

消费者代码：

package com.jieting.mq.rabbit.receive;

import java.io.IOException;

import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;
import com.rabbitmq.client.ConsumerCancelledException;
import com.rabbitmq.client.QueueingConsumer;
import com.rabbitmq.client.ShutdownSignalException;

public class MessageReceive {

    private static final String QUENE_NAME = "hello";

    public static void main(String[] args) throws IOException, ShutdownSignalException, ConsumerCancelledException,
                                          InterruptedException {

        ConnectionFactory connectionFactory = new ConnectionFactory();
        Connection newConnection = connectionFactory.newConnection();
        Channel createChannel = newConnection.createChannel();

        createChannel.queueDeclare(QUENE_NAME, true, false, false, null);
        System.out.println(" [*] Waiting for messages. To exit press CTRL+C");

        QueueingConsumer queueingConsumer = new QueueingConsumer(createChannel);
        createChannel.basicConsume(QUENE_NAME, true, queueingConsumer);
        while (true) {
            QueueingConsumer.Delivery delivery = queueingConsumer.nextDelivery();
            String message = new String(delivery.getBody());
            System.out.println(" [x] Received '" + message + "'");
        }
    }
}
