RabbitMQ入门Demo
之前环境安装已经介绍过了,下面直接跑个Demo。
1、添加Maven依赖
<dependency>
<groupId>org.springframework.amqp</groupId>
<artifactId>spring-rabbit</artifactId>
<version>1.4.6.RELEASE</version>
</dependency>
<dependency>
<groupId>com.rabbitmq</groupId>
<artifactId>amqp-client</artifactId>
<version>2.2.0</version>
</dependency>
2、发送类:
package com.jimmy.demo.test; import java.io.IOException; import com.rabbitmq.client.Channel; import com.rabbitmq.client.Connection; import com.rabbitmq.client.ConnectionFactory; public class Send { private final static String QUEUE_NAME = "hello"; public static void main(String[] args) throws IOException { 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()); System.out.println(" [x] Sent '" + message + "'"); channel.close(); connection.close(); } }
接收类:
package com.jimmy.demo.test; import com.rabbitmq.client.Channel; import com.rabbitmq.client.Connection; import com.rabbitmq.client.ConnectionFactory; import com.rabbitmq.client.QueueingConsumer; public class Reqv { 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"); 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(" [x] Received '" + message + "'"); } } }
测试先运行Reqv,再运行Send两次,看到如下消费者能够接受到2条消息了
这次我们关掉Receive,再次运行Send,然后点击管理网页上的Queue。
点击hello进去,并点击Get Message,可以看到Hello World消息的确已经传送到RabbitMQ的服务器端了
