Utilizzo del tempo joda con JPA/hibernate e spring

Question

Vorrei insistere per creare data e ora del db. Ho qualche esperienza con lezioni di data e ora, ma non mi piacciono.

Recentemente ho iniziato a utilizzare il tempo di Joda. Devo dire che la biblioteca è la migliore per lavorare con data e ora.

Per ora mi piacerebbe mantenere l'oggetto DateTime da joda.

Ho provato già:

@Type(type="org.joda.time.contrib.hibernate.PersistentDateTime") 
private DateTime creationDate; 

Ma sfortunatamente dosnt lavoro. traccia Qui è impilare:

E il mio frammento di pom.xml:

<dependency> 
    <groupId>joda-time</groupId> 
    <artifactId>joda-time</artifactId> 
    <version>2.5</version> 
</dependency> 

spero che qualcuno mi aiuterà.

È possibile utilizzare Jadira per questo scopo:

Add questo al tuo pom.xml:

<dependency> 
    <groupId>org.jadira.usertype</groupId> 
    <artifactId>usertype.extended</artifactId> 
    <version>3.2.0.GA</version> 
</dependency> 

e mettere questo nelle proprietà di Hibernate (hibProperties metodo nella classe config):

properties.put("jadira.usertype.autoRegisterUserTypes", "true"); 

Dopo aver fatto questo è possibile rimuovere il @Type annotazioni dalle vostre proprietà Joda e dovrebbe funzionare bene (opere per me sia per Joda che per JSR-310).
