Dubbo在启动的时候遇到的问题

Question

在学习Dubbo的时候运行出现这中情况：org.apache.curator.CuratorConnectionLossException: KeeperErrorCode = ConnectionLoss
后面的是这个，关键是我也不知道这是怎么回事，百度来百度去也没有结果。

基于Monster 组和GPT的调写：
这个错误提示表明在运行Dubbo的过程中，发生了连接断开的异常（CuratorConnectionLossException），可能是因为与Zookeeper的连接丢失（KeeperErrorCode = ConnectionLoss）。可能的原因包括：

Zookeeper服务没有启动或已停止，导致Dubbo无法连接到Zookeeper；
网络连接不稳定或存在丢包现象，导致Dubbo与Zookeeper之间的连接中断；
Dubbo配置文件中的Zookeeper地址配置错误，无法连接到正确的Zookeeper地址。

建议检查Dubbo配置文件中Zookeeper地址配置是否正确，并确认Zookeeper服务已经启动。如果以上都没有问题，可以考虑检查网络连接稳定性，或者增加重试机制来应对连接断开的情况。
