IProvideConfiguration类，如UnicastBusConfig被多次调用

本文关键字：调用 UnicastBusConfig IProvideConfiguration | 更新日期: 2023-09-27 18:01:35

我已经用IProvideConfiguration实现了一个类

当我的总线创建时，它被调用4次。因为有逻辑在那里做一些映射的收集-逻辑也执行了4次。我是否手动需要保持一个"初始化"的标志，以防止它多次运行，或者我可以在NServiceBus中使用一些东西，或者我使用这个错误?

这些是导致4个调用的调用堆栈:

IProvideConfiguration类，如UnicastBusConfig被多次调用

实现IProvideConfiguration的类将在每次调用者试图访问它的配置(在您的示例中是UnicastBusConfig)时创建。您可以将第一个创建的实例保留为静态变量，并在调用IProvideConfiguration实现的GetConfiguration时始终返回相同的配置实例。我建议将任何初始化逻辑移出实现IProvideConfiguration的类。
