问题描述

我想用Struts2在Google App Engine上开发我的项目。对于数据库我有两个选项JPA和JDO。请你们建议我吗？两者对我来说都是新的，我需要学习它们。所以我会在你回复之后专注于一个。

谢谢。

推荐答案

JPA是Sun的持久标准，JDO是IMHO的死亡（实际上，它已经死了，但仍在移动）。换句话说，JPA似乎是一项长期投资。所以我想我会选择JPA，如果两者对我来说都是新手。

JPA is Sun's standard for persistence, JDO is IMHO dying (actually, it's dead but still moving). In other words, JPA seems to be a better investment on the long term. So I guess I'd choose JPA if both were new to me.
