我在我的 Java 项目中使用 jDate Chooser
我需要从 jDateChooser 检索日期并将其放入 mySQL 表中
我使用的方法是 newBirthDate=(Date)inBirthDate.getDate();
newBirthDate 是一个日期变量(前面定义的数据类型)
inBirthDate 是日期选择器
然后，我简单地将它放入mysql中 我在输出 Pane 中遇到巨大且难以理解的异常 我不知道该怎么办 请帮忙 See picture

最佳答案
将从日期选择器中获取的日期声明为java.util.Date
然后用它转换成java.sql.Date然后插入mysql:
sqlDate= new java.sql.Date(utilDate.getTime());
感谢大家的帮助:)
