IProvideConfiguration 类 例如UnicastBusConfig 被多次调用
IProvideConfiguration classes e.g. UnicastBusConfig get called multiple times
我已经使用 IProvideConfiguration
实现了 class
创建总线时，它被调用了 4 次。因为那里有做一些映射收集的逻辑——这个逻辑也被执行了 4 次。我是否需要手动保留带有 'Initialized' 的标志以防止它多次 运行 或者我可以在 NServiceBus 中使用某些东西还是我用错了？
这些是导致 4 个调用的调用堆栈：

每次调用者尝试访问它的配置时都会创建实现 IProvideConfiguration 的 class（在您的情况下 UnicastBusConfig）。您可以将第一个创建的实例保留为静态变量，并且在调用 IProvideConfiguration 实现的 GetConfiguration 时始终 return 相同的配置实例。我建议将任何初始化逻辑移出 class 实现 IProvideConfiguration.
