Problem mit Hibernate und Named Query

[marky8264]

hey,

ich möchte eine kleine Anwendung mit Spring und Hibernate schreiben. Dabei habe ich eine Named Query erstellt mit einem Parameter.
Hier die Entität:

@Entity
@Table(name="PersonVersion")
@SuppressWarnings("serial")
@NamedQueries({
	@NamedQuery(name="PersonVersion.findLastByPersonId"
		,query="from PersonVersion v where v.id = :Id")
})
public class PersonVersion implements Serializable{
}

Dabei bekomme ich folgende Exception:

org.springframework.dao.InvalidDataAccessApiUsageException: org.hibernate.QueryParameterException: Position beyond number of declared ordinal parameters. Remember that ordinal parameters are 1-based! Position: 1; nested exception is java.lang.IllegalArgumentException: org.hibernate.QueryParameterException: Position beyond number of declared ordinal parameters.

Hier mein Aufruf:

List<PersonVersion> lst=(List<PersonVersion>)this.getJpaTemplate()
			.findByNamedQuery("PersonVersion.findLastByPersonId",id);

Ich hoffe ihr könnt mir weiter helfen.

Habe gerade heraus gefunden, dass wenn ich die findByNamedQuery-Methode verwende, dann kann ich keine named Parameter verwenden.
Um die named Parameter zu verwenden muss man findByNamedQueryAndNamedParams aufrufen. 😉
