2.6.5 迁移 2.7.9 不兼容

• I have searched the issues of this repository and believe that this is not a duplicate.
• I have checked the FAQ of this repository and believe that this is not a duplicate.

Environment

• Dubbo version: 2.7.9
• Operating System version: mac
• Java version: 1.8

Steps to reproduce this issue

1. 升级前的dubbo版本是2.6.5
2. 升级后的dubbo版本是2.7.9
3. 2.6.5有一段这样的代码，在新版本中不兼容，新版本中应该如何处理： Set<ProviderInvokerWrapper> providerInvokerWrapperSet = ProviderConsumerRegTable.getProviderInvoker(providerModel.getServiceName()); for (ProviderInvokerWrapper providerInvokerWrapper : providerInvokerWrapperSet) { if (providerInvokerWrapper.isReg()) { isReg = true; break; } }

`Set consumerInvokerWrapperSet = ProviderConsumerRegTable.getConsumerInvoker(consumerModel.getServiceName());

                for (ConsumerInvokerWrapper consumerInvokerWrapper : consumerInvokerWrapperSet) {
                    Map<String, Invoker> urlInvokerMap = consumerInvokerWrapper.getRegistryDirectory().getUrlInvokerMap();`

Pls. provide [GitHub address] to reproduce this issue.
