javax.persistence.PersistenceException： org.hibernate.PersistentObjectException： 分离的实体传递给 persist
2022-09-01 15:19:32
将JPA与Hibernate一起使用，我在运行以下代码时遇到了异常。我第一次运行它时，一切顺利，数据入到数据库中。第二次，当数据应该更新时，它失败了：
@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（） 简单地调用 EntityManager.persist（） 方法。
这是我的精品课：
@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"),
})
public class Boutique implements IPersistentObject, IPubliable<Manifestation> {
/**
*
*/
private static final long serialVersionUID = -3038903536445432584L;
public static final String LOAD_BOUTIQUE_BY_IDWEBSC = "load.boutique.by.idwebsc";
protected long idBoutique;
protected Site site;
protected Long idOrigine;
protected String urlLogo;
protected String urlBoutique;
protected boolean selected;
protected long idWebSC;
protected Date datePublication;
protected Date dateModification;
@Override
@Id
@GeneratedValue(generator="SEQ_BOUTIQUE")
@Column(name = "ID_BOUTIQUE", unique = true, nullable = false, precision = 8, scale = 0)
public Long getId() {
return this.idBoutique;
}
public void setId(Long idBoutique) {
this.idBoutique = idBoutique;
}
@Override
public void setIdOrigine(Long idOrigine) {
this.idOrigine = idOrigine;
}
@Override
@Column(name = "IDORIGINE", length = 7)
public Long getIdOrigine() {
return this.idOrigine;
}
@Override
@Temporal(TemporalType.DATE)
@Column(name = "DATE_PUBLICATION", length = 7)
public Date getDatePublication() {
return datePublication;
}
@Override
public void setDatePublication(Date datePublication) {
this.datePublication = datePublication;
}
@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;
}
}
最后，我的堆栈跟踪：

我在Tomcat 7.0.32服务器上运行Java 7.0.11。
有什么想法吗？
