Hibernate只要坚持日期 [英] Hibernate to persist Dates as long

问题描述

有没有办法告诉Hibernate java.util.Date应该持久化？我需要这个来解决MySQL中缺少的毫秒分辨率问题。

你能想到这种方法的缺点吗？

解决方案

您可以使用虚拟属性来完成此功能。

并为Date对象添加一个get / set。 setter设置了long值，getter创建了一个新的Date。

我看不到任何缺点，只是可能想要使用Date在你的应用程序中（这就是为什么我认为虚拟属性解决方案很好）

Is there a way to tell Hibernate that java.util.Date should be persisted as long? I need this to get around the missing millisecond resolution in MySQL.

Could you think of any drawbacks of this approach?

解决方案

you can do it with a virtual attribute.

So you map a long, and add a get/set for a Date object. The setter sets the long value and the getter creates a new Date with the long.

And I can't see any drawbacks, only that probably you want to use a Date in your app (that's why I think the virtual attribute solution is goodish)
