In Java, with JPA2, which class should be used to store date information?

There are three options that I see for date processing in Java, but maybe I will show you some better alternatives.

  • java.util.Date is good, but it is a very simple class with many design flaws.
  • java.util.Calendar - which is slightly better, but still really clumbsy to work with
  • JODA time - what is better to work with, but I'm not sure how much it will persist using JPA2

I would like to use JODA Time, because these are promises a simpler API, but persistence is more important, so I would be well versed in Calendar or Date if JODA Time is not saved.

Ultimately, I need something that is stored in the database as a date, preferably with an easy-to-use API.

java.util.Calendar is saved with JPA2 as well as with java.util.Date, just make sure you add the @Temporal annotation to the property. JODA time preservation is better supported in Hibernate, however I don't think it supports temporary optimization queries included in some relational databases, so if you plan to request a date attached to java.util objects, it will be your best choice. If you do not plan to query this column, any serialization object can be saved using JPA.

We have JODA LocalDate sleep mode directly. Of course, there is some kind of configuration and something to do. You can watch this project: Joda-Time Hibernate
