hibernate 4 and joda-time

A distinct paucity of documentation, means it might be helpful for me to write down the steps required for integration. Make sure your libraries are up to date.

You’ll need : [assuming you already have hibernate4]

Latest version of joda-time

<dependency>
    <groupId>joda-time</groupId>
    <artifactId>joda-time</artifactId>
    <version>2.0</version>
</dependency>

and usertype lib

<dependency>
    <groupId>org.jadira.usertype</groupId>
    <artifactId>usertype.core</artifactId>
    <version>3.0.0.CR1</version>
</dependency>

Then use the following in entity classes (doesn’t have to be LocalDateTime, could be any of the persisted classes available) :

import org.joda.time.LocalDateTime;

and for column definition:

@Column(name="updated", nullable = false)
@Type(type="org.jadira.usertype.dateandtime.joda.PersistentLocalDateTime")
private LocalDateTime updated;
