推荐答案
JPA 是 Sun 的持久性标准，JDO 恕我直言正在消亡(实际上，它已经死了但仍在移动).换句话说，从长远来看，JPA 似乎是更好的投资.所以我想如果两者对我来说都是新的，我会选择 JPA.
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.
