问题：由于一些依赖相关的原因，决定升级Dubbo到2.7.15，注册中心用的是nacos，每个集群有两个实例，在测试环境单实例测试都正常，但是部署到rancher上的集群环境后，发现只有provider启动了，其他consumer都没有启动起来，查了下consumer的报错全是： 08:04:13.782 [main] WARN o.s.b.w.s.c.AnnotationConfigServletWebServerApplicationContext 559- Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'p4bBusinessBrokersServiceImpl': Unsatisfied dependency expressed through field 'ip4bWalletsService'; nested exception...
不太理解 ZookeeperRegistryNotifier 的 notify() 方法里面，为什么要进行 sleep ？ 我一开始以为是这里说的【延迟通知】https://cn.dubbo.apache.org/zh/blog/2022/06/23/%e6%b5%85%e6%9e%90-dubbo-3.0-%e4%b8%ad%e6%8e%a5%e5%8f%a3%e7%ba%a7%e5%9c%b0%e5%9d%80%e6%8e%a8%e9%80%81%e6%80%a7%e8%83%bd%e7%9a%84%e4%bc%98%e5%8c%96/#%E5%BB%B6%E8%BF%9F%E9%80%9A%E7%9F%A5 但是阅读代码之后，发现应该起不到这里说的【延迟通知】的效果。 **_看了 org.apache.dubbo.registry.RegistryNotifier#notify 的实现，org.apache.dubbo.registry.zookeeper.ZookeeperRegistry.ZookeeperRegistryNotifier#notify 的实现的确有问题，ZookeeperRegistryNotifier实现不了【阻塞期间，多次通知的合并】_**
项目升级dubbo3.1后自定义异常捕获失效 ，debug后发现dubbo调用被 InvocableHandlerMethod类拦截  自定义的dubbo的ExceptionFilter不生效
