java - Hibernate一对一导致: 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。它是一个 CRUD 应用程序。我使用 hibernate 来进行所有的增删改查操作。这对他们所有人都有效。但是，一对一，我厌倦了尝试。最后它给了我以下错误。

引起:org.hibernate.MappingException:无法确定类型:org.ppbni.splatter.model.Wafat，表:用户，列:[org.hibernate.mapping.Column(wafatDetail) ]

这是我的用户管理模型，

最佳答案

我认为您的映射错误，并且希望在 UserAdmin 和 Wafat 类之间进行 OneToOne 映射，并且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 注释进行以下映射。

}
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. 如果了解您正在学习 hibernate，那么我建议首先尝试小类授课。太多字段可能会让您感到困惑。
