Question

Al usar JPA con Hibernate, obtuve una excepción al ejecutar el siguiente código. La primera vez que lo ejecuto, todo va bien y los datos se insertan en la base de datos. La segunda vez, cuando los datos deben actualizarse, falla:

@AdminTx
public void processSite(Site site) {
    FluxBoutiqueMapping mapping = mapper.generateMappingFromUrl(site);

    Boutique boutique;
    for (FluxBoutiqueMapping.Boutique fluxBoutique : mapping.getListe().getBoutiques()) {
        log.error("Dans la boucle");
        boutique = daoAdmin.namedQuerySingle(Boutique.LOAD_BOUTIQUE_BY_IDWEBSC, fluxBoutique.getId());
        log.error("boutique : "+boutique);

        if (boutique==null) {
            log.error("Dans le new");
            boutique = new Boutique();
        }

        boutique.setSite(site);
        boutique.setUrlLogo(fluxBoutique.getLogo());
        boutique.setUrlBoutique(fluxBoutique.getUrl());
        boutique.setSelected(false);
        boutique.setIdWebSC(fluxBoutique.getId());
        boutique.setDateModification(new Date());

        boutiqueDao.persist(boutique);

        boutique = null;
    }
}

boutiqueDao.persist () simplemente llama al método EntityManager.persist ().

Y aquí mi clase de boutique:

@Entity
@Table(name = "BOUTIQUE")
@SequenceGenerator(name = "SEQ_BOUTIQUE", sequenceName = "SEQ_BOUTIQUE")
@NamedQueries(value = {
        @NamedQuery(name = Boutique.LOAD_BOUTIQUE_BY_IDWEBSC, query = "from Boutique b where b.idWebSC=?1"),

    }

    @Override

    }

    @Override
    @Temporal(TemporalType.DATE)
    @Column(name = "DATE_MODIFICATION", length = 7)
    public Date getDateModification() {
        return dateModification;
    }

    public void setDateModification(Date dateModification) {
        this.dateModification = dateModification;
    }

    @Override
    public void update(Manifestation newer) {
        // TODO Auto-generated method stub

    }

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "ID_SITE")
    @ForeignKey(name = "FK_BOUTIQUE_SITE")
    public Site getSite() {
        return site;
    }

    public void setSite(Site site) {
        this.site = site;
    }

    @Column(name = "URL_LOGO", length = 255)
    public String getUrlLogo() {
        return urlLogo;
    }

    public void setUrlLogo(String urlLogo) {
        this.urlLogo = urlLogo;
    }

    @Column(name = "URL_BOUTIQUE", length = 255)
    public String getUrlBoutique() {
        return urlBoutique;
    }

    public void setUrlBoutique(String urlBoutique) {
        this.urlBoutique = urlBoutique;
    }

    @Column(name = "SELECTED")
    public boolean isSelected() {
        return selected;
    }

    public void setSelected(boolean selected) {
        this.selected = selected;
    }

    @Column(name = "ID_WEBSC", length = 7)
    public long getIdWebSC() {
        return idWebSC;
    }

    public void setIdWebSC(long idWebSC) {
        this.idWebSC = idWebSC;
    }

}

Y por último, mi stacktrace:

Estoy ejecutando Java 7.0.11 en un servidor Tomcat 7.0.32.

¿Alguna idea?

Answer 1

Su principal problema es que está cargando entidades en un DAO:

boutique = daoAdmin.namedQuerySingle(
    Boutique.LOAD_BOUTIQUE_BY_IDWEBSC, fluxBoutique.getId());

Pero luego guardándolos con otro:

boutiqueDao.persist(boutique);

En el caso de las entidades existentes, esto generará un error de entidad separada, porque la entidad tiene un id, pero no existe en la unidad de trabajo del segundo DAO. Por supuesto, incluso si hubiera usado el mismo DAO para leer / persistir, todavía tendría problemas porque no debería usar persist para guardar las entidades existentes. Intenta esto en su lugar:

Lee las entidades que usan el mismo DAO que vas a usar para guardarlas

boutique = boutiqueDAO.namedQuerySingle (Boutique.LOAD_BOUTIQUE_BY_IDWEBSC, fluxBoutique.getId ());

Cambie su manejo de nuevas boutiques, para hacer una persistencia inmediata del objeto.

if (boutique==null) {
    log.error("Dans le new");
    boutique = new Boutique();
    boutiqueDAO.persist(boutique);
}

Cambiar la última persistencia a una combinación

boutique.setIdWebSC(fluxBoutique.getId());
boutique.setDateModification(new Date());

boutique = boutiqueDao.merge(boutique);

Answer 2

Persist está diseñado para objetos transitorios nuevos y falla si la identificación ya está asignada. Probablemente debería llamar a saveOrUpdate lugar de persist .

Alternativamente, puede verificar si el objeto ya está contenido en su administrador de entidades, y si es así, haga un

entityManager.merge(yourObject);

,más

entityManager.persist(yourObject);
