当我从“默认包”重命名包时，出现类未找到异常
当我从 java 中的“默认包”重命名包时，出现类未找到异常。当我在默认包中运行代码时，代码工作正常，但是当我将代码粘贴到 Eclipse 中的新 java 项目和新包中时，即使上面提到的类明显存在于新的包裹。怎么了？请帮我 ：（
I get a class not found exception when i rename the package from "default package" in java. When i run the code within the default package, the code works fine but when i paste the code into a new java project in eclipse and into a new package, there is a classnotfound exception thrown even when the class referred to above is clearly present in the new package. What is wrong? please help me :(

我的猜测是，您仍在尝试使用现有的应用程序启动器启动应用程序，该启动器引用“默认”包中的类。
创建一个新的启动器，或编辑现有启动器的详细信息。
当然，这是假设您在启动时遇到异常。如果情况并非如此，您需要向我们提供更多详细信息。
编辑：好的，现在您已经发布了异常，它更有意义 - 您正在尝试反序列化包含对类
FaceBundle的引用的数据。重命名类会破坏序列化数据 - 就这么简单。您可以摆弄Java序列化中的东西，但我自己还没有这样做过。我怀疑您想要创建自己的
ObjectInputStream子类并覆盖resolveClass。My guess is that you're still trying to start the application with the existing application launcher, which is referring to the class in the "default" package.
Either create a new launcher, or edit the details of the existing one.
Of course, that's assuming you get the exception on launch. If that's not the case, you need to give us a lot more details.
EDIT: Okay, now you've posted the exception, it makes a lot more sense - you're trying to deserialize data which includes a reference to the class
FaceBundle. Renaming classes breaks serialized data - it's as simple as that.You can fiddle around with things in Java serialization, but I haven't done so myself. I suspect you'd want to create your own subclass of
ObjectInputStreamand overrideresolveClass.
