Question

我有一个使用带有Schema鉴别符的多租户系统，并使用EclipseLink 2.7.3。正是为了避免这个（Bug 493235）（和其他）错误，我才移至EclipseLink 2.7.3。但是，出现以下异常：

java.lang.IllegalArgumentException: Exception [EclipseLink-6069] (Eclipse Persistence Services - 2.7.3.v20180807-4be1041): org.eclipse.persistence.exceptions.QueryException
Exception Description: The field [`database_1`.library.libId] in this expression has an invalid table in this context.
Query: ReadAllQuery(name="Library.findByReservationId" referenceClass=Library jpql="SELECT l FROM Library l WHERE l.libId = (SELECT r.lib.libId FROM Reservation r WHERE r.reservId = :reservId)")

我的实体看起来像这样：

@Entity
@Multitenant(value = TABLE_PER_TENANT)
@TenantTableDiscriminator(type = SCHEMA, contextProperty = MULTITENANT_PROPERTY_DEFAULT)
@Table(name = "library")
@XmlRootElement
@NamedQueries({
    @NamedQuery(name = "Library.findByReservId", query = "SELECT l FROM Library l WHERE l.libId = (SELECT r.lib.libId FROM Reservation r WHERE r.reservId = :reservId)")})
public class Library implements Serializable {

    private static final long serialVersionUID = 1L;
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Basic(optional = false)
    @Column(name = "libId")
    private Long libId;
    ...
    @OneToMany(cascade = CascadeType.ALL, mappedBy = "libId")
    private List<Reservation> reservList;
    ...
}

@Entity
@Multitenant(value = TABLE_PER_TENANT)
@TenantTableDiscriminator(type = SCHEMA, contextProperty = MULTITENANT_PROPERTY_DEFAULT)
@Table(name = "reservation")
@XmlRootElement
public class Reservation implements Serializable {

    private static final long serialVersionUID = 1L;
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Basic(optional = false)
    @Column(name = "reservId")
    private Long reservId;
    @JoinColumn(name = "lib", referencedColumnName = "libId")
    @ManyToOne(optional = false)
    private Library lib;
    @OneToMany(cascade = CascadeType.ALL, mappedBy = "reservation")
    private List<BookReservation> bookReservationList;
    @Transient
    private List<Long> bookIdList;
    ...
}

该错误应该在2.7版中消失了。我错了吗？这里还会有其他事情吗？这个错误还会困扰EclipseLink 2.7.3吗？谢谢您的回答。

EclipseLink 2.7.3引发异常，就像Bug 493235一样
