<dependency>
<groupId>joda-time</groupId>
<artifactId>joda-time</artifactId>
<version>${joda-time.version}</version>
</dependency>
<dependency>
<groupId>joda-time</groupId>
<artifactId>joda-time-hibernate</artifactId>
<version>${joda-time-hibernate.version}</version>
</dependency>
with joda-time.version = 1.4 and joda-time-hibernate.version = 1.0
To get it all working with Hibernate you will need a package-info.java file
in the same directory as your model classes. Sample included below:
@TypeDefs( { @TypeDef(name = "JodaDateTime", typeClass =
PersistentDateTime.class),
@TypeDef(name = "JodaLocalTime", typeClass =
PersistentLocalTimeAsTime.class),
@TypeDef(name = "JodaLocalDate", typeClass = PersistentLocalDate.class)})
package com.mycompany.model;
import org.hibernate.annotations.TypeDef;
import org.hibernate.annotations.TypeDefs;
import org.joda.time.DateTime;
import org.joda.time.LocalDate;
import org.joda.time.LocalTime;
import org.joda.time.contrib.hibernate.PersistentDateTime;
import org.joda.time.contrib.hibernate.PersistentLocalDate;
import org.joda.time.contrib.hibernate.PersistentLocalTimeAsTime;
You may need to add some additional typedefs as required. Once that lot is
in place simply annotate the getter of each Joda-time field with the correct
type, e.g.:
@Type(type = "JodaDateTime")
