相关疑难解决方法(0)

我在我的游戏应用程序中使用Jodatime,但目前不必做来回转换自/至一束java.util.Date和java.sql.Time.

由于jodatime包含在Play发行版中,我认为可能有更好的方法来实现这一点.有没有什么办法可以让我的模型字段DateTimes,而不是java.util.Date和java.sql.Time这样的转换是自动完成的？还有另一种简化方法吗？

我会坚持db创建日期和时间.我有日期和时间课程的一些经验,但我不喜欢它们.

最近我开始使用Joda时间.我不得不说,图书馆是最好的日期和时间.

现在我想从joda继承DateTime对象.

我已经尝试过了:

@Type(type="org.joda.time.contrib.hibernate.PersistentDateTime")
private DateTime creationDate;

但它不幸地工作了.这是堆栈跟踪:
