休眠：通过持久性属性的反射访问字段 [private java.lang.Integer ] 时出错

当我尝试获取实体属性时，我有奇怪的问题：

Hibernate: 
    select
        tarifklsk0_.ID as ID1_12_0_,
        tarifklsk0_.FK_TARIF as FK_TARIF2_12_0_,
        tarifservp1_.FK_TARIF as FK_TARIF2_11_1_,
        tarifservp1_.ID as ID1_11_1_,
        tarifservp1_.ID as ID1_11_2_,
        tarifservp1_.FK_TARIF as FK_TARIF2_11_2_,
        tarifservp1_.N1 as N3_11_2_ 
    from
        TR.TARIFXKLSK tarifklsk0_ 
    left outer join
        TR.TARIF_SERV_PROP tarifservp1_ 
            on tarifklsk0_.FK_TARIF=tarifservp1_.FK_TARIF 
    where
        tarifklsk0_.ID=?

我的实体：

TarifServProp

    public void setId(Integer id) {

    public Integer getFkTarif() {
        return fkTarif;
    }

    public void setFkTarif(Integer fkTarif) {
        this.fkTarif = fkTarif;
    }

    public Integer getN1() {
        return n1;
    }

    public void setN1(Integer n1) {
        this.n1 = n1;
    }

}

我的测试模块：

    public static void main(String[] args) {
        SessionFactory sf = HibernateUtil.getSessionFactory();
        Session sess = sf.openSession();
        sess.beginTransaction();

        TarifKlsk k2=sess.get(TarifKlsk.class, 1027303);
        for (TarifServProp t : k2.getTarifservprop()) {
             System.out.println("Tar="+t.getN1());
        }

        System.out.println("End init");

我做错了什么？我已经检查了这些实体的所有字段，并且所有字段都正确命名....

涨停2

我发现我的子实体不包含与主fk_tarif相对应fk_tarif的记录...但我认为这并不重要，为什么存在错误？
