点击“lulei”这个，进入设置权限界面：

设置完成后：

再运行成功了。

附上代码：

package xx.mq;
import java.util.concurrent.TimeoutException;

import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;

public class Producer {

    private final static String QUEUE_NAME = "hello world";

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

        Connection connection = null;
        Channel channel = null;
        try {
            /* 创建连接工厂 */
            ConnectionFactory factory = new ConnectionFactory();
            factory.setHost("*.*.*.*");//此处IP隐去
            factory.setUsername("lulei");
            factory.setPassword("123456");
            factory.setPort(5672);
            /* 创建连接 */
            connection = factory.newConnection();
            /* 创建信道 */
            channel = connection.createChannel();

            // 声明一个队列：名称、持久性的（重启仍存在此队列）、非私有的、非自动删除的
            channel.queueDeclare(QUEUE_NAME, true, false, false, null);

            String message = "hello world..."; // 需发送的信息

            /* 发送消息，使用默认的direct交换器 */
            channel.basicPublish("", QUEUE_NAME, null, message.getBytes());
            System.out.println("Send message -> " + message);

        } catch(Exception e){
            e.printStackTrace();
        }finally {
            /* 关闭连接、通道 */
            if(channel!=null){

    }

                System.out.println("Received the message -> " + message);
            }
        };

        // 将消费者绑定到队列，并设置自动确认消息（即无需显示确认，如何设置请慎重考虑）
        channel.basicConsume(QUEUE_NAME, true, consumer);
