rabbit MQ在后台运行代码时报错Exception in thread "main" java.util.concurrent.TimeoutException at com.rabbitmq

rabbit MQ在后台运行代码时报错Exception in thread “main” java.util.concurrent.TimeoutException

首先在Linux上下载了rabbit QM
修改如下配置后启动


进入rabbit QM添加用户

然后在idea运行代码时报错：
代码如下

/**

• 消费者
  */
  public class Recv {
  private final static String QUEUE_NAME = “simple_queue”;

  public static void main(String[] argv) throws Exception {
  // 获取到连接
  Connection connection = ConnectionUtil.getConnection();
  // 创建通道
  Channel channel = connection.createChannel();
  // 声明队列
  channel.queueDeclare(QUEUE_NAME, false, false, false, null);
  // 定义队列的消费者
  DefaultConsumer consumer = new DefaultConsumer(channel) {
  // 获取消息，并且处理，这个方法类似事件监听，如果有消息的时候，会被自动调用
  @Override
  public void handleDelivery(String consumerTag, Envelope envelope, BasicProperties properties,
  byte[] body) throws IOException {
  // body 即消息体
  String msg = new String(body);
  System.out.println(" [x] received : " + msg + “!”);

       }
   };
   // 监听队列，第二个参数：是否自动进行消息确认。
   channel.basicConsume(QUEUE_NAME, true, consumer);
  

  }
  }

/**

• 消费者,手动进行ACK
  */
  public class Recv2 {
  private final static String QUEUE_NAME = “simple_queue”;

  public static void main(String[] argv) throws Exception {
  // 获取到连接
  Connection connection = ConnectionUtil.getConnection();
  // 创建通道
  final Channel channel = connection.createChannel();
  // 声明队列
  channel.queueDeclare(QUEUE_NAME, false, false, false, null);
  // 定义队列的消费者
  DefaultConsumer consumer = new DefaultConsumer(channel) {
  // 获取消息，并且处理，这个方法类似事件监听，如果有消息的时候，会被自动调用
  @Override
  public void handleDelivery(String consumerTag, Envelope envelope, BasicProperties properties,
  byte[] body) throws IOException {
  // body 即消息体
  String msg = new String(body);
  System.out.println(" [x] received : " + msg + “!”);
  // 手动进行ACK
  channel.basicAck(envelope.getDeliveryTag(), false);
  }
  };
  // 监听队列，第二个参数false，手动进行ACK
  channel.basicConsume(QUEUE_NAME, false, consumer);
  }
  }

/**

• 生产者
  */
  public class Send {

  private final static String QUEUE_NAME = “simple_queue”;

  public static void main(String[] argv) throws Exception {
  // 获取到连接
  Connection connection = ConnectionUtil.getConnection();
  // 从连接中创建通道，使用通道才能完成消息相关的操作
  Channel channel = connection.createChannel();
  // 声明（创建）队列
  channel.queueDeclare(QUEUE_NAME, false, false, false, null);
  // 消息内容
  String message = “Hello World!”;
  // 向指定的队列中发送消息
  channel.basicPublish("", QUEUE_NAME, null, message.getBytes());

   System.out.println(" [x] Sent '" + message + "'");
  
   //关闭通道和连接
   channel.close();
   connection.close();
  

  }
  }
  无论运行哪一个，都报同样的错误，错误如下；

网上各种尝试，都不行，求大神帮忙!
