Java Hibernate分配不正确的数据库ID

情况是这样的：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\u id，它包含SecurityContact的主键。Hibernate成功地自动生成此列的ID号。 第二列（我们称之为agent_id）包含第二个表（我们称之为AgentContact）的主键的值，该表的主键列称为contact_id。正如您可能猜到的，此agent_id列以及引用的列contact_id是SecurityContact和AgentContact之间的联接列之一。 SecurityContactlet的第三列（我们称之为audit_id）还包含AgentContact主键的值。这也是SecurityContact和AgentContact之间的联接列，在AgentContact中引用了列contact_id。SecurityContact中的条目与AgentContact中的条目之间的关系是多对一的。 因此，基本上，此SecurityContact表将代理id和审核id连接到安全id。代理id和审核id可以相同或不同，这取决于AgentContact中的两个条目是相同还是不同

现在问题来了：即使这两个条目不同，Hibernate似乎也为这两个条目设置了相同的id，这个id是SecurityContact的auditContact的联系人id。这两个条目应该不同，agent_id包含agent的contact_id，audit_id包含来自同一个表AgentContact的审计的contact_id。有人知道为什么吗

我先为我的长篇大论道歉。以下是SecurityContact的代码：

 /**

@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;
    }

    }

    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) {

    }

    public void setAgentContact(AgentContact agentContact) {

        return this.auditContact;
    }

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

}

以下是AgentContact表的代码：

        return this.bank;
    }

    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;
    }


}

SecurityContact的第三列我们称之为audit_id，它还包含SecurityContact主键的值。这是打字错误吗？我猜出来了。问题不在Hibernate端，而是在Flex端。在数据收集同步之间形成竞争条件。添加睡眠功能解决了这个问题。
