У меня есть приложение Java EE, которое работает на tomcat с парой классов сущностей и использует eclipselink 2.1 и jpa 2.0.
Объектами являются EmailNotification и EmailNotificationQueueRow.
@Entity
public class EmailNotification implements Serializable, IEntity<Integer> {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO, generator = "emailGen")
@SequenceGenerator(name = "emailGen", sequenceName = "SQ_EMAIL_NOTIFICATIONS", allocationSize=1)
@Basic(optional = false)
@Column(name = "EMAIL_ID")
private Integer emailId;
@Basic(optional = false)
@Column(name = "EMAIL_SUBJECT")
private String emailSubject;
@Basic(optional = false)
@Column(name = "EMAIL_BODY")
private String emailBody;
@Basic(optional = false)
@Column(name = "SENT_FROM_EMAIL_ADDRESS")
private String sentFromEmailAddress;
@Column(name = "SEND_TO_ORG_ID")
private Integer sendToOrgId;
@Column(name = "SEND_TO_EMAIL_ADDRESS")
private String sendToEmailAddress;
@Column(name = "CARBON_COPY_ORG_ID")
private Integer carbonCopyOrgId;
@Column(name = "CARBON_COPY_EMAIL_ADDRESS")
private String carbonCopyEmailAddress;
@Column(name = "BCC_ORG_ID")
private Integer bccOrgId;
@Column(name = "BCC_EMAIL_ADDRESS")
private String bccEmailAddress;
@Column(name = "PROJECT_ID")
private Integer projectId;
//getters and setters
}
@Entity
public class EmailNotificationQueueRow implements Serializable, IEntity<Integer> {
private static final long serialVersionUID = 1L;
@Id
@Basic(optional = false)
@Column(name = "EMAIL_QUEUE_ID")
private Integer emailQueueId;
@Basic(optional = false)
@Column(name = "EMAIL_ID")
private int emailId;
@Basic(optional = false)
@Column(name = "REQUEST_DATE")
@Temporal(TemporalType.TIMESTAMP)
private Date requestDate;
@Basic(optional = false)
@Column(name = "MESSAGE_SENT_FLAG")
private String messageSentFlag;
@Column(name = "MESSAGE_SENT_DATE")
@Temporal(TemporalType.TIMESTAMP)
private Date messageSentDate;
@JoinColumn(name = "EMAIL_ID", referencedColumnName = "EMAIL_ID", updatable = false, insertable = false)
@OneToOne(fetch = FetchType.LAZY)
private EmailNotification emailNotification;
//getters and setters
}
Всякий раз, когда я устанавливаю отношение переменной emailNotification к FetchType.LAZY (как указано выше), класс не является тканым. Он зарегистрирован для ткачества, но никогда не был.
Журнал ниже. Сущность EmailNotification сплетена, но не сущность EmailNotificationQueueRow. Есть идеи?

Обновление
Я использую строку eclipselink javaagent для запуска tomcat. Также есть другие сопоставления OneToOne, которые лениво загружаются в моем проекте, которые переплетаются. Только этот один класс (EmailNotificationQueueRow) не переплетается.
