ClassNotFoundException 正是如此.找不到作为引用的类.使用第三方库时，您必须确保它们的依赖项(如果有)也包含在您的类路径中.

ClassNotFoundException is exactly that. A class that is references cannot be found. When working with third party libraries, you must ensure that their dependancies (if any) are also included in your class path.

没有看到实际的堆栈跟踪，很难缩小问题的范围，但我会检查我添加的第三方库的依赖项是否也包含在类路径中.

Without seeing the actual stacktrace, its difficult to narrow down the problem, but I would check if the dependancies of the third party libraries that I am adding are also included in the class path.

希望有所帮助.
