Question

我知道这一定很简单，但我花了大约2个小时的时间搜索，直到现在我才找到任何我无法理解的解决方案。

好吧，我可以在没有Eclipse控制台任何问题的情况下使用我的程序，但是当我尝试从Windows命令行运行它时，我从Hibernate类中得到错误。

从Eclipse运行时，我得到了这个：

从命令行运行时，这就是我得到的：

我一直在寻找Java Build Path，选择Maven Dependencies进行导出。我希望有人可以帮助我。感谢...

Answer 1

这意味着您的Hibernate和Mysql的环境设置不正确。它在eclipse中运行，因为它会有一些内置的依赖项。因此，将所需的库添加到正确的类路径中，然后尝试。

Answer 2

在通过控制台运行程序时，您缺少类路径上所需的jar。您可以通过控制台检查eclipse中的所有必需库/ jar，列表以及类路径中的那些jar。

代码在eclipse中工作，但不在命令行中工作
