脚本：
Springboot:2.0.4
dubbo:2.6.2
Zookeeper：3.6.1
zkclient:java库
所有这些装置都在Kubernetes运行。
Zookeeper：
使用zkcli.sh，我可以看到提供者已成功注册。但是当从消费者应用程序连接时，它抛出以下错误。
实际堆栈跟踪错误：

Caused by: java.lang.IllegalStateException: Failed to check the status of the service a.b.c.UploadFacade. No provider available for the service a.b.c.UploadFacade from the url zookeeper://zookeeper-svc:2181/com.alibaba.dubbo.registry.RegistryService?application=rest&dubbo=2.6.2&interface=a.b.c.UploadFacade&logger=slf4j&methods=getMerchants,uploadInstanceDetails&organization=abc&pid=1&register.ip=192.168.19.144&revision=1.0.12&side=consumer&timestamp=1606480530254 to the consumer 192.168.19.144 use dubbo version 2.6.2

我没有在谷歌上找到太多信息。
过帐前检查：
已验证springboot使用者能够访问zookeeper（已成功连接）。
已验证zookeeper已注册提供程序（使用zkcli.sh）
zookeeper日志：
