使用 nacos 1.1.4 时没问题
使用nacos 1.2.0 时候出现 dubbo 提供者不停的重复注册服务.
nacos为单节点模式,没有使用集群

  • 经查是因为nacos这边在处理心跳信息时,当心跳信息中没有clusterName的时候,没有为RsInfo设置clusterName的默认值.导致后面的处理根据clusterName获取到的 cluster 为null, 调用 cluster 时出现异常导致后面更新心跳时间的逻辑没有执行.(因为使用了ScheduledExecutorService 所以异常没有抛出)
  • 由于心跳时间没有更新,心跳检查任务发现心跳超时调用了注销服务的接口
  • 注销服务接口注销了服务后通知了dubbo, dubbo又把该服务重新注册

以上流程无限循环...

目前已修复该问题
