我正在使用带有 WebLogic 10.3.5 容器管理事务的 EclipseLink 2.1.3 与 Oracle 11g DB 交互。

我可以毫无问题地选择数据，但无法持久化实体。

日志中没有引发异常或错误，但没有数据提交到 ANNOUNCEMENT_DELIVERY_LOG 表。

AnnouncementDeliveryLog 实体与 Announcement 实体具有 @ManyToOne 关系。我首先检索一个现有的 Announcement Entity，然后根据查询结果创建一个 AnnouncementDeliveryLog Entity，将这两个 Entities 关联，并持久化。

任何关于我做错了什么或如何从 WebLogic 上的 EclipseLink 获取更多日志信息的建议都将不胜感激。

AnnouncementDeliveryLog 实体：

@Entity
@Table(name = "ANNOUNCEMENT_DELIVERY_LOG")
public class AnnouncementDeliveryLog implements Serializable {

    @Id
    @Column(nullable = false)
    @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="ANNOUNCEMENT_DELIVERY_LOG_SEQ")
    @SequenceGenerator(name="ANNOUNCEMENT_DELIVERY_LOG_SEQ", sequenceName="ANNOUNCEMENT_DELIVERY_LOG_SEQ")
    private BigDecimal id;
    @Column(name = "RECIPIENT_ADDRESS ", nullable = false, unique = true, length = 240)
    private String recipientAddress;
    @ManyToOne
    @JoinColumn(name = "ANNOUNCEMENT_ID ")
    private Announcements announcement;
}

公告实体：

@Entity
@Table(name = "ANNOUNCEMENTS")
public class Announcements implements Serializable {
    @Id
    @Column(nullable = false)
    private BigDecimal id;
    @OneToMany(mappedBy = "announcement")
    private List<AnnouncementDeliveryLog> announcementDeliveryLogList;
}

会话外观 SLSB 执行事务：

@Stateless(name = "DeliveryEngineSessionFacade",
           mappedName = "Announcements-JMSDeliveryEngine-DeliveryEngineSessionFacade")
public class DeliveryEngineSessionFacadeBean implements DeliveryEngineSessionFacadeLocal {
    @Resource
    SessionContext sessionContext;
    @PersistenceContext(unitName = "JMSDeliveryEnginePersistenceUnit")
    private EntityManager em;

    private List<AnnouncementDeliveryLog> createNormalizedEmailADLsForAnnouncement(int announcementId) {
        List<Object[]> rawResultList;
        ArrayList<AnnouncementDeliveryLog> typedResultList = new ArrayList<AnnouncementDeliveryLog>();

        Query query =
            em.createNamedQuery(AnnouncementDeliveryLog.FIND_NORMALIZED_RECIPIENTS_FOR_ANNOUNCEMENT);
        query.setParameter(1, announcementId);
        rawResultList = query.getResultList();

        for (Object[] resultElement : rawResultList) {
            AnnouncementDeliveryLog adl = new AnnouncementDeliveryLog(getAnnouncementById(announcementId), (String)resultElement[1], (String)resultElement[2], "TO_SEND");
            adl = persistAnnouncementDeliveryLog(adl);
            typedResultList.add(adl);
        }

        return typedResultList;
    }

public AnnouncementDeliveryLog persistAnnouncementDeliveryLog(AnnouncementDeliveryLog announcementDeliveryLog) {
    em.persist(announcementDeliveryLog);
    return announcementDeliveryLog;
}

public Announcements getAnnouncementById(int announcementId) {
    Query query = em.createNamedQuery(Announcements.FIND_BY_ID);
    query.setParameter("id", announcementId);
    return (Announcements)query.getSingleResult();
}

}

SLSB 调用会话外观：

@Stateless(name = "RecipientsPopulationTimer",
           mappedName = "Announcements-AnnouncementDeliveryEngine-RecipientsPopulationTimer")
@Local({RecipientsPopulationTimerLocal.class})
public class RecipientsPopulationTimerBean implements RecipientsPopulationTimerLocal {
    @EJB
    DeliveryEngineSessionFacadeLocal sessionFacade;
}

RecipientsPopulationTimerBean 被一个有超时的组件调用。

这意味着 EJB 事务被回滚，因为 DB 事务花费了太长时间。

设置@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)适当的 DB 事务方法可防止 EJB 超时和关联的 DB 回滚。
