Hibernate One To One引起：org.hibernate.MappingException：无法确定类型

标签： java spring hibernate

现在，我正在学习hibernate，并开始在我的项目中使用它。这是一个CRUD应用程序。我使用hibernate进行所有的crud操作。它适用于所有人。但是，一对一，我厌倦了尝试它。最后它给了我以下错误。

Caused by: org.hibernate.MappingException: Could not determine type for: org.ppbni.splatter.model.Wafat, at table: user, for columns: [org.hibernate.mapping.Column(wafatDetail)]

这是我的useradmin模型，

}

这是我的控制器，

    ModelAndView mav = new ModelAndView("beritaduka");

    SessionFactory factory = new Configuration().configure().buildSessionFactory();

    List<UserAdmin> useradmin = session.createQuery("from UserAdmin").list();
    for (UserAdmin useradmin1 : useradmin){
        System.out.println(useradmin1.getNama_tengah() + " , "
                + useradmin1.getKota() + ", "
                + useradmin1.getWafat().getKode_wafat());
    }

    session.close();
    factory.close();

    return mav;

}

我认为您的映射错误，希望在OneToOne和UserAdmin类之间进行Wafat映射，两者共享相同的主键。

如果是这样，您可能需要尝试使用MapsId和PrimaryKeyJoinColumn注释的以下映射。

@Column(name="usia_wafat")
public int getUsia_wafat() {
    return usia_wafat;
}
public void setUsia_wafat(int usia_wafat) {
    this.usia_wafat = usia_wafat;
}
@Temporal(TemporalType.TIMESTAMP)
@Column(name="tgl_makam")
public Date getTgl_makam() {
    return tgl_makam;
}
public void setTgl_makam(Date tgl_makam) {
    this.tgl_makam = tgl_makam;
}
@Column(name="tempat_makam")
public String getTempat_makam() {
    return tempat_makam;
}
public void setTempat_makam(String tempat_makam) {
    this.tempat_makam = tempat_makam;
}

private UserAdmin useradmin;

@OneToOne
@MapsId
@JoinColumn(name="no_dana")
public UserAdmin getUseradmin() {
    return useradmin;
}
public void setUseradmin(UserAdmin useradmin) {
    this.useradmin = useradmin;
}

}

并保存实体：

UserAdmin ua = new UserAdmin();
Wafat w = new Wafat();
w.setKode_wafat("Kode_Wafat");
ua.setWafat(w);
w.setUseradmin(ua);
session.persist(ua);

一些建议：

  1. 您在字段和属性上混合了hibernate注释。坚持一种方法，在字段或属性上设置hibernate注释。
  2. 如果你明白自己正在学习hibernate，那么我建议先尝试使用较小的类。太多的领域，它可能会让你感到困惑。
