Question

我的应用程序第一次运行时出现以下错误...

引起：异常[EclipseLink-7155]（Eclipse Persistence Services - 2.0.1.v20100213-r6600）：org.eclipse.persistence.exceptions.ValidationException 异常描述：实体类[class Novartis.OTM.Data.Db.Entities.DtsTmpClass]上属性[lapId]的类型[类Lap]不是序列化映射的有效类型。属性类型必须实现Serializable接口。

以下是相关实体。

@SequenceGenerator(name="SEQ_DTS_TMP_CLASS", sequenceName="SEQ_DTS_TMP_CLASS", allocationSize=1)
@Entity
@Table(name = "DTS_TMP_CLASS")
@NamedQueries({
    @NamedQuery(name = "DtsTmpClass.findAll", query = "SELECT d FROM DtsTmpClass d"),
    @NamedQuery(name = "DtsTmpClass.findByDtsTmpClassId", query = "SELECT d FROM DtsTmpClass d WHERE d.dtsTmpClassId = :dtsTmpClassId")})
public class DtsTmpClass implements Serializable {
    private static final long serialVersionUID = 1L;
    @Id
    @Basic(optional = false)
    @Column(name = "DTS_TMP_CLASS_ID")
    @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="SEQ_DTS_TMP_CLASS")
    private Integer dtsTmpClassId;
    @JoinColumn(name = "LAP_ID", referencedColumnName = "LAP_ID")
    @ManyToOne(optional = false, fetch=FetchType.EAGER)
    private Lap lapId;
    ...
}

如下所示，输入Lap implements Serializable！

@SequenceGenerator(name="SEQ_LAP", sequenceName="SEQ_LAP", allocationSize=1)
@Entity
@Table(name = "LAP")
@NamedQueries({
    @NamedQuery(name = "Lap.findAll", query = "SELECT l FROM Lap l"),
    @NamedQuery(name = "Lap.findByLapId", query = "SELECT l FROM Lap l WHERE l.lapId = :lapId"),
    @NamedQuery(name = "Lap.findByDeprecate", query = "SELECT l FROM Lap l WHERE l.deprecate = :deprecate")})
public class Lap implements Serializable {
    private static final long serialVersionUID = 1L;
    @Id
    @Basic(optional = false)
    @Column(name = "LAP_ID")
    @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="SEQ_LAP")
    private Integer lapId;
    @Column(name = "DEPRECATE")
    private Character deprecate;
    @OneToMany(cascade = CascadeType.ALL, mappedBy = "lapId")
    private Collection<LapAnal> lapAnalCollection;
    @OneToMany(cascade = CascadeType.ALL, mappedBy = "lapId")
    private Collection<LapDomain> lapDomainCollection;
    @JoinColumn(name = "ASSAY_PLATFORM_ID", referencedColumnName = "LOOKUP_ID")
    @ManyToOne(optional = false, fetch=FetchType.EAGER)
    private Lookup assayPlatformId;
    @JoinColumn(name = "LABORATORY_ID", referencedColumnName = "LOOKUP_ID")
    @ManyToOne(optional = false, fetch=FetchType.EAGER)
    private Lookup laboratoryId;
    @OneToMany(cascade = CascadeType.ALL, mappedBy = "lapId")
    private Collection<DtsTmpClass> dtsTmpClassCollection;
    ...
}

奇怪的是，我只是缩短了表名和列名，因此Oracle不会超过30个字符的限制。它只是工作。

我很困惑！

谢谢，

克里斯
