Question

情况就是这样：我有一个映射表，我们称之为SecurityContact，有三列。

第一列（我们称之为security_id）包含SecurityContact的主键。 Hibernate成功自动生成此列的ID号。
第二列（我们称之为agent_id）包含第二个表的主键值（我们称之为AgentContact），其主键列名为contact_id。您可能已经猜到，此agent_id列与引用的列contact_id是SecurityContact和AgentContact之间的连接列之一。
SecurityContact的第三列（我们称之为audit_id）也包含AgentContact主键的值。这也是SecurityContact和AgentContact之间的连接列，再次引用了AgentContact中的列contact_id。 SecurityContact中的条目与AgentContact中的条目之间的关系是多对一的。

基本上，这个SecurityContact表将agent_id和audit_id连接到security_id。 agent_id和audit_id可以相同或不同，具体取决于AgentContact中的两个条目是相同还是不同。

现在问题就在于：即使两个条目不同，Hibernate似乎也为它们都设置了相同的id，这个id是SecurityContact的auditContact的contact_id。这两个条目应该不同，agent_id包含代理的contact_id，audit_id包含审计的contact_id（来自同一个表，AgentContact）。任何人都知道为什么？

我为这么长时间的啰嗦而道歉。以下是SecurityContact的代码：

 /**
 * The persistent class for the SecurityContact database table.

 */
@Entity
@FXClass(kind=FXClassKind.REMOTE)
public class SecurityContact implements Serializable {
    private static final long serialVersionUID = 1L;
    @Transient private String uid;
    @FXIgnore
    public String getUid() {
        if (uid == null) {
            uid = "" + securityId;
        }
        return uid;
    }

    public void setUid(String uid) {
        this.uid = uid;
    }

    @Id

    @Column(name="security_id")
    private Long securityId;

    //bi-directional many-to-one association to AgentContact
    @ManyToOne

    private AgentContact agentContact;

    //bi-directional many-to-one association to AuditContact
    @ManyToOne
    @JoinColumn(name="audit_id", referencedColumnName="contact_id")
    private AgentContact auditContact;

    public SecurityContact() {
    }
    @FXKeyColumn
    public Long getSecurityId() {
        return this.securityId;
    }

    public void setSecurityId(Long securityId) {
        this.securityId = securityId;
    }

    public String getCreateDate() {
        return this.createDate;
    }

    public void setCreateDate(String createDate) {
        this.createDate = createDate;
    }

    public String getCreateUser() {
        return this.createUser;
    }

    public void setCreateUser(String createUser) {
        this.createUser = createUser;
    }

    public String getModifyDate() {
        return this.modifyDate;
    }

    public void setModifyDate(String modifyDate) {
        this.modifyDate = modifyDate;
    }

    public String getModifyUser() {
        return this.modifyUser;
    }

    public void setModifyUser(String modifyUser) {
        this.modifyUser = modifyUser;
    }
    @FXManyToOne(parent="com.counterpartcontacts.entity.AgentContact", property="contactId")
    public AgentContact getAgentContact() {
        return this.agentContact;
    }

    public void setAgentContact(AgentContact agentContact) {
        this.agentContact = agentContact;
    }
    @FXManyToOne(parent="com.counterpartcontacts.entity.AgentContact", property="contactId")
    public AgentContact getAuditContact() {
        return this.auditContact;
    }

    public void setAuditContact(AgentContact auditContact) {
        this.auditContact = auditContact;
    }

}

以下是AgentContact表的代码：

    public void setBank(Bank bank) {
        this.bank = bank;
    }

    }

    public String getFax() {
        return this.fax;
    }

    public void setFax(String fax) {
        this.fax = fax;
    }

    public String getModifyDate() {
        return this.modifyDate;
    }

    public void setModifyDate(String modifyDate) {
        this.modifyDate = modifyDate;
    }

    public String getModifyUser() {
        return this.modifyUser;
    }

    public void setModifyUser(String modifyUser) {
        this.modifyUser = modifyUser;

    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPhone() {
        return this.phone;

    public void setPhone(String phone) {
        this.phone = phone;
    }
    @FXOneToMany(fillArguments="contactId")
    public Set<SecurityContact> getSecurityContacts() {
        return this.securityContacts;
    }

    public void setSecurityContacts(Set<SecurityContact> securityContacts) {
        this.securityContacts = securityContacts;
    }
