一.pom.xml
<dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> <exclusions> <exclusion> <groupId>org.junit.vintage</groupId> <artifactId>junit-vintage-engine</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>com.rabbitmq</groupId> <artifactId>amqp-client</artifactId> <version>3.6.5</version> </dependency> </dependencies>
二.生产者
public class Producer { public static void main(String[] args) throws IOException, TimeoutException { //创建一个连接工厂 ConnectionFactory connectionFactory = new ConnectionFactory(); connectionFactory.setHost("192.168.10.132"); connectionFactory.setPort(5672); connectionFactory.setVirtualHost("/"); //创建连接 Connection connection = connectionFactory.newConnection(); //通过连接创建一个Channel Channel channel = connection.createChannel(); //通过Channel发送数据 channel.basicPublish("","hello",null,"hello world".getBytes()); //关闭连接 channel.close(); connection.close(); } }
这里注意channel.basicPublish方法的第一个参数(exchange)和第二个参数(routingKey),如果没有指定exchange,指定了routingKey,而routingKey与消费者类中指定的queue的name相同,会通过RabbitMQ的默认Exchange(AMQP default)进行路由。
三.消费者
public class Consumer { public static void main(String[] args) throws IOException, TimeoutException, InterruptedException { //创建一个连接工厂 ConnectionFactory connectionFactory = new ConnectionFactory(); connectionFactory.setHost("192.168.10.132"); connectionFactory.setPort(5672); connectionFactory.setVirtualHost("/"); //创建连接 Connection connection = connectionFactory.newConnection(); //通过连接创建一个Channel Channel channel = connection.createChannel(); //创建一个队列 String queueName = "hello"; channel.queueDeclare(queueName,true,false,false,null); //创建一个消费者 QueueingConsumer consumer = new QueueingConsumer(channel); //设置Channel channel.basicConsume(queueName,true,consumer); //获取消息 while (true){ QueueingConsumer.Delivery delivery = consumer.nextDelivery(); String msg = new String(delivery.getBody()); System.out.println("消费端:"+msg); } } }
四.运行
先运行消费者,再运行生产者。
在消费者的控制台可以接收到生产者发送的消息。
