这很奇怪。我刚刚更改了我的 Web 应用程序中的一些内容，但无法还原这些内容，因为我不记得我更改了什么。

我在尝试运行我的 webapp 时遇到此异常:

我只记得我添加了 Joda Time 和 JSR 250 API，但两者都不依赖于 commons-logging？!

如果需要更多代码，请告诉我，我会提供。

最佳答案

这似乎是一个 IDE 错误...我将 Eclipse 与 WTP 和 Maven 一起使用。有一个 tmp0 和 tmp1 文件夹，我重新创建了工作区。现在又可以用了……奇怪的问题。

关于java - 找不到公共(public)日志记录类，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/11800638/
