Question

我有以下实体：

@Entity
@Table(name = "follow_ups")
@Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED)
@Access(AccessType.FIELD)
public class FollowUp extends EntityObject {

    private static final long serialVersionUID = -1343114665843716990L;

    @ManyToOne(optional = false)
    @JoinColumn(name = "contact_id")
    private Contact contact;

    @ManyToOne(optional = true)
    @JoinColumn(name = "dossier_id")
    private Dossier dossier;

    @ManyToOne(optional = true)
    @JoinColumn(name = "website_item_id")
    private WebsiteItem websiteItem;

    @ManyToOne(optional = true, fetch = FetchType.LAZY)
    @JoinColumn(name = "invoice_id")
    private Invoice invoice;

    @Column(name = "message_date")
    @OrderBy("message_date DESC")
    private Date messageDate;

    @Column(name = "message")
    private String message;

    @ManyToOne
    @JoinColumn(name = "creator")
    private BackendUser creator;

    public Contact getContact() {
        return contact;
    }

    public void setContact(Contact contact) {
        this.contact = contact;
    }

    public Dossier getDossier() {
        return dossier;
    }

    public void setDossier(Dossier dossier) {
        this.dossier = dossier;
    }

    public WebsiteItem getWebsiteItem() {
        return websiteItem;
    }

    public void setWebsiteItem(WebsiteItem websiteItem) {
        this.websiteItem = websiteItem;
    }

    public Invoice getInvoice() {
        return invoice;
    }

    public void setInvoice(Invoice invoice) {
        this.invoice = invoice;
    }

    public BackendUser getCreator() {
        return creator;
    }

    public void setCreator(BackendUser creator) {
        this.creator = creator;
    }

    public Date getMessageDate() {
        return messageDate;
    }

    public void setMessageDate(Date messageDate) {
        this.messageDate = messageDate;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }
}

使用检查发票上的任何内容的条件，例如invoice.id，或者急切地提取发票时，会创建以下sql（这只是它执行的许多查询之一）：

SELECT vatdetails0_.invoice_id  AS invoice_5_40_1_,
  vatdetails0_.id               AS id1_39_1_,
  vatdetails0_.id               AS id1_39_0_,
  vatdetails0_.invoice_id       AS invoice_5_39_0_,
  vatdetails0_.invoice_vat_type AS invoice_2_39_0_,
  vatdetails0_.vat              AS vat3_39_0_,
  vatdetails0_.vat_amount       AS vat_amou4_39_0_

此查询不正确，生成的错误是关于第一个THEN关键字，该关键字无法在该位置使用，而且我以前从未使用过hibernate。在互联网上找不到有关hibernate生成错误查询的信息。

使用的标准是最简单的情况：

session.createCriteria(getEntityClass())

什么可能是错的，我应该看看吗？如何深入了解休眠以查看问题所在？也许应该将其记录为hibernate错误？

使用的hibernate版本是：4.3.10.Final 使用的方言：POSTGRESQL。
