It occurs to me that I should probably share this. I've been using
Jorge's wonderful Scala wrapper for JodaTime and I needed to persist
DateTime and LocalDate. I found a Hibernate project that makes this
possible. (Note that Jorge's wrapper is a work in progress and doesn't
cover everything in JodaTime, but you can just use the JodaTime classes
directly, which I did for DateTimeFormatter and DateTimeFormatterBuilder.)
In pom.xml:
<dependency>
<groupId>org.scala-tools</groupId>
<artifactId>time</artifactId>
<version>2.7.5-0.2-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>joda-time</groupId>
<artifactId>joda-time</artifactId>
<version>1.6</version>
</dependency>
<dependency>
<groupId>joda-time</groupId>
<artifactId>joda-time-hibernate</artifactId>
<version>1.1</version>
</dependency>
In the JPA entity classes:
@Type{val `type`="org.joda.time.contrib.hibernate.PersistentDateTime"}
@Column{val name="created_at", val updatable = false}
var createdAt: DateTime = DateTime.now
Gets persisted as a "timestamp without time zone" in PostgreSQL.
@Type{val `type`="org.joda.time.contrib.hibernate.PersistentLocalDate"}
@Column{val name = "born_on"}
var bornOn: LocalDate = new LocalDate()
Gets persisted as a "date" in PostgreSQL.
