我在生产中遇到了很多奇怪的错误，这些错误只发生在少数用户身上，所以99%的用户都还好。

这是TranslationWorkerFactory的代码。我正在使用dagger辅助注入将依赖项注入到工作类。
class TranslationWorkerFactory @Inject constructor(
private val workerFactories: Map<Class<out ListenableWorker>, @JvmSuppressWildcards Provider<ITranslationWorkerFactory>>
) : WorkerFactory() {
override fun createWorker(
appContext: Context,
workerClassName: String,
workerParameters: WorkerParameters
): ListenableWorker? {
val foundEntry =
workerFactories.entries.find { Class.forName(workerClassName).isAssignableFrom(it.key) }
val factoryProvider = foundEntry?.value
?: throw IllegalArgumentException("unknown worker class _name: $workerClassName")
return factoryProvider.get().create(appContext, workerParameters)
}
}
我不知道为什么会发生这种事。工作人员所做的是下载和解析大型json，因此这可能是抛出异常的原因，但这只是我的猜测，如果它可能是相关的。
有人知道发生这种情况的原因吗？
感谢
例如，您很可能已经移动/重命名了工人类(TranslationWorker(在重构期间。
如果是请继续阅读。
复制步骤：
- 启动应用程序(旧版本(并等待工作程序启动
- 将worker类移到另一个包中，重新生成应用程序
- 启动应用程序并等待系统运行工作程序
到目前为止，我还没有找到好的解决方案。但有一个可行的选择。主要思想-是用WorkerFactory中的实际路径替换工人类的错误路径。更多细节在这个后
