rabbitmq java 开发_rabbitmq的java简单的实现

2.安装完之后  启动rabbitmq, sudo rabbitmq-server

3.下载jar包

4.最简单的hello world的实现

Sender类

package com.lubby.test;

import java.io.IOException;

import com.rabbitmq.client.Channel;

import com.rabbitmq.client.Connection;

import com.rabbitmq.client.ConnectionFactory;

public class ClientSender {

private final static String QUEUE_NAME = "hello";

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

ConnectionFactory factory = new ConnectionFactory();

factory.setHost("127.0.0.1");

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(" Sent: '" + message + "'");

channel.close();

connection.close();

}

}

Receiver类

package com.lubby.test;

import com.rabbitmq.client.Channel;

import com.rabbitmq.client.Connection;

import com.rabbitmq.client.ConnectionFactory;

import com.rabbitmq.client.QueueingConsumer;

public class ClientReceiver {

private final static String QUEUE_NAME = "hello";

public static void main(String[] argv) throws java.io.IOException,

java.lang.InterruptedException {

ConnectionFactory factory = new ConnectionFactory();

factory.setHost("127.0.0.1");

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");

QueueingConsumer consumer = new QueueingConsumer(channel);

channel.basicConsume(QUEUE_NAME, true, consumer);

while (true) {

QueueingConsumer.Delivery delivery = consumer.nextDelivery();

String message = new String(delivery.getBody());

System.out.println(" Received:'" + message + "'");

}

}

}

5.測试

启动ClientReceiver-

[*] Waiting for messages. To exit press CTRL+C启动ClientSender

Sent: 'Hello World'

ClientReceiver接收到消息

[*] Waiting for messages. To exit press CTRL+C

Received:'Hello World'
