Persist Joda-time's DateTime via Hibernate

Question

I\'m using Jodatime in my Play app, but currently having to do a bunch of converting back and forth from/to java.util.Date and java.sql.Time.

Answer 1

1. Joda recommends to use the UserType libraries with Hibernate 4.0, the version of Hibernate bundled with Play 1.2.x (see: http://joda-time.sourceforge.net/contrib/hibernate/index.html).

2. The proper way to handle the dependency is using the dependencies.yml file, including a line like this:

   - org.jadira.usertype -> usertype.jodatime 2.0.1
   

Answer 2

For Hibernate 3 add the following annotation to your date field:

@Type(type="org.joda.time.contrib.hibernate.PersistentDateTime")

Hibernate will now do the dirty work for you.

(Make sure you have joda-time-hibernate.jar in your classpath)

UPDATE:

For Hibernate 4 and 5 add the following annotation:

@Type(type="org.jadira.usertype.dateandtime.joda.PersistentLocalDateTime")

(Make sure you have jadira-usertype-core.jar in your classpath)

Answer 3

We should enable two jars in Hibernate 4 project:

• compile("joda-time:joda-time:2.8")
• compile("org.jadira.usertype:usertype.jodatime:2.0.1")

Answer 4

Instead of putting the @Type annotation at each of your Joda properties you can add this in your jpa properties

#Hibernate config
jadira.usertype.autoRegisterUserTypes=true

and it should work just fine.

ps. jadira-usertype-core.jar should be in your classpath.
