Hibernate 中出现此错误的原因是什么？

这是我的类，它有一个来自 Ogrenciler.class 的名为 ogrenciId 的外键
@Entity
@Table(name = "alınandersler", schema="okulotomasyon")
public class AlinanDersler implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name="ID")
private int id;
@ManyToOne(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
@JoinColumn(name = "öğrenciID")
private Ogrenciler ogrenciId;
@ManyToOne(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
@JoinColumn(name="dersID")
private AcılanDersler dersId;
//Constructors getters and setters
这是我 child 的类(class)
@Entity
@Table(name = "öğrenciler",schema = "okulotomasyon")
public class Ogrenciler implements Serializable{
/**

private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@OneToOne(targetEntity = Kisiler.class, fetch = FetchType.EAGER, cascade = CascadeType.ALL)
@JoinColumn(name="ID")
private Kisiler ogrnid;
@Column(name = "no")
private String no;
@Column(name = "e_posta")
private String e_posta;
@Column(name = "kayitTarihi")
private Date kayitTarihi;
@Column(name = "sinif")
private int sinif;
//Constructors getters and setters
这是我的基类
@Entity
@Table(name = "kisiler",schema = "okulotomasyon")
public class Kisiler{
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name ="ID")
private int id;
@Column(name ="isim")
private String isim;
@Column(name ="soyisim")
private String soyisim;
@Column(name ="TC")
private String TC="";
@Column(name ="dogumTarihi")
private Date dogumTarihi;
@Column(name ="telNo")
private String telNo;
@Column(name ="kisiTürü")
private String kisiTuru;
//Constructors getters and setters
我不知道问题是什么，你能帮我吗？
最佳答案
我解决了这个问题也许对你有帮助。
我将 referencedColumnName = "ID" 添加到 @JoinColumn 注释中，这对我有帮助。
关于java - AnnotationException : A Foreign key refering has the wrong number of column. 应该是 0，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/59346464/
