将默认的RabbitMQ Exchange与默认的Exchange绑定起来，可以将消息传递到所有使用该Exchange的队列中。示例代码如下：

import com.rabbitmq.client.*;

public class RabbitMQExample {
    private final static String QUEUE_NAME = "my_queue";
    private final static String EXCHANGE_NAME = "";

    public static void main(String[] argv) throws Exception {
        /*创建连接工厂*/
        ConnectionFactory factory = new ConnectionFactory();
        factory.setHost("localhost");
        /*创建连接*/
        Connection connection = factory.newConnection();
        /*创建Channel*/
        Channel channel = connection.createChannel();

        /*声明队列*/
        channel.queueDeclare(QUEUE_NAME, false, false, false, null);
        /*绑定默认的Exchange*/
        channel.queueBind(QUEUE_NAME, EXCHANGE_NAME, "");

        /*定义消息*/
        String message = "Hello World!";
        /*发送消息*/
        channel.basicPublish(EXCHANGE_NAME, "", null, message.getBytes("UTF-8"));
        System.out.println(" [x] Sent '" + message + "'");

        /*关闭连接*/
        channel.close();
        connection.close();
    }
}
