下面是一个简单的Java代码示例,包含生产者和消费者,以及相应的Maven POM文件来实现RabbitMQ的生产和消费: Java代码示例:
// 生产者 import com.rabbitmq.client.ConnectionFactory; import com.rabbitmq.client.Connection; import com.rabbitmq.client.Channel;
public class RabbitMQProducer { private final static String QUEUE_NAME = "hello";
public static void main(String[] args) throws Exception {
ConnectionFactory factory = new ConnectionFactory();
factory.setHost("localhost");
try (Connection connection = factory.newConnection();
Channel channel = connection.createChannel()) {
channel.queueDeclare(QUEUE_NAME, false, false, false, null);
String message = "Hello RabbitMQ!";
channel.basicPublish("", QUEUE_NAME, null, message.getBytes());
System.out.println("Sent: " + message);
}
}
}
// 消费者 import com.rabbitmq.client.*;
public class RabbitMQConsumer { private final static String QUEUE_NAME = "hello";
public static void main(String[] args) throws Exception {
ConnectionFactory factory = new ConnectionFactory();
factory.setHost("localhost");
try (Connection connection = factory.newConnection();
Channel channel = connection.createChannel()) {
channel.queueDeclare(QUEUE_NAME, false, false, false, null);
System.out.println("Waiting for messages...");
DeliverCallback deliverCallback = (consumerTag, delivery) -> {
String message = new String(delivery.getBody(), "UTF-8");
System.out.println("Received: " + message);
};
channel.basicConsume(QUEUE_NAME, true, deliverCallback, consumerTag -> {});
}
}
} Maven POM文件:
<dependency>
<groupId>com.rabbitmq</groupId>
<artifactId>amqp-client</artifactId>
<version>5.12.0</version>
</dependency>
在上面的示例中,我们创建了一个名为 rabbitmq-example 的Maven项目。在POM文件中,我们添加了RabbitMQ客户端的依赖,以便在代码中使用RabbitMQ相关的类和接口。根据你使用的RabbitMQ客户端版本,你可能需要更改amqp-client的版本号。
请注意,为了使代码正常运行,确保你已经在本地运行了RabbitMQ代理,且与代码中设置的主机名(localhost)相匹配。
