尊敬的开发者 你好

我的服务配置如下

dubbo:
  application:
    name: ${spring.application.name}
    register-mode: instance
    qos-port: 33333
  registry:
    address: multicast://224.5.6.7:1234?unicast=false
  protocol:
    name: tri
    port: 20880
  consumer:
    check: false
    cache: false
    validation: true
    timeout: 3000

出现了官方文档说的 5-10 问题 https://cn.dubbo.apache.org/zh-cn/overview/mannual/java-sdk/faq/5/10/

版本：dubbo-spring-boot-starter:3.2.0 spring-boot:2.7.2

调用该服务报错，提示No provider available for the service xxxxx

看上去像是后注册服务的服务目录没有初始化，导致后续通过服务目录添加Invoker失败：

先注册的服务： (发布DemoService，DemoService引用 DemoServiceB，url有绑定的RegistryDirectory，可以更新成功) 屏幕截图 2023-10-08 230442

后注册的服务： (发布DemoServiceB,DemoServiceB 引用 DemoService, url不存在绑定的RegistryDirectory，导致调用 DemoServiceB 时出现类似错误) 屏幕截图 2023-10-08 225043

可以考虑暂时先用ZooKeeper代替 @AlbumenJ
