在另一台计算机上运行应用程序时出现InvalidClassException

标签： java swing

这是在我在另一台计算机上打开项目后发生的，登录屏幕后出现此错误。  我在我的桌面计算机中包含了我用来创建它的所有库，它可以正常工作。  我找不到错误并修复它

这是第180到185行的代码，在错误中引用：

CB_vendor(javax.swing.JComboBox)java.beans.Beans.instantiate(getClass().getClassLoader(), "newproject.NewJFrame_CB_vendor");
} catch (ClassNotFoundException e) {
    e.printStackTrace();
} catch (java.io.IOException e) {
    e.printStackTrace();
} ##

将项目导入NetBeans后，我以正常方式运行它：project ---right click -----run

完整错误：

2 个答案:

答案 0 :(得分：5)

看起来你已经序列化了一个JComboBox，但是serialVersionUID在运行时知道的类和被序列化的类之间并不匹配。如果查看Javadoc for the Serializable interface，它会解释如何使用该字段来确保序列化版本以及JVM想要从序列化对象创建的内容是相同的。

由于该类是Java标准库的一部分，我建议您运行在一个JVM版本上序列化JComboBox的代码，并尝试在另一个版本上反序列化它。

作为旁注，序列化像JComboBox这样的UI元素很少是合适的。通常，您希望序列化数据，而不是显示数据的任何内容（因此您保存JComboBox的状态 - 选择的内容 - 然后将其还原到新的JComboBox中）。这样你就不会遇到这样的问题。

答案 1 :(得分：4)

您已在JRE版本中序列化JComboBox。来自Javadoc：

  

警告：此类的序列化对象与以后的Swing版本不兼容。当前的序列化支持适用于运行相同版本Swing的应用程序之间的短期存储或RMI。
