Java JPA-表每类继承-Id冲突

我有一个带有ID字段的父类和两个子类。我已经为每个类继承应用了表。 这两个表中的某些行具有相同的标识符。（同一身份证）

当调用JpaRepository的findAll（）时，我有org.hibernate.PropertyAccessException

我能做些什么来解决冲突？我无法更改这些表中的ID，因为它们有很多依赖项和外键约束

@Entity
@Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
public abstract class Parent implements Serializable {

private static final long serialVersionUID = 1L;

@Id
@TableGenerator(name = "content_id_generator",
        table = "generic_sequences",
        pkColumnName = "sequence_name",
        valueColumnName = "sequence_value",
        pkColumnValue= "content_seq",
        allocationSize = 20)
@GeneratedValue(strategy = GenerationType.TABLE, generator = "content_id_generator")
@Column(updatable = false)
private Long id;

@Column(length = 250, nullable = false)
@NotNull
@Size(min = 1, max = 250)
private String title;

...

有Child1和Child2扩展父类的子类。

@Entity
@Table(name = "text_id_changed")
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name = "type")
public abstract class DependentCalss implements Serializable {

private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(updatable = false)
private Long id;

...

@Entity
@DiscriminatorValue("DependentCalssChild1")
public class DependentCalssChild1 extends DependentCalss {

private static final long serialVersionUID = 1L;

@ManyToOne
@JoinColumn(name = "child_1_id")
private Child1 child1;
...

还有一个继承依赖于内容。

@Entity
@Table(name = "text_id_changed")
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name = "type")
public abstract class DependentCalss implements Serializable {

private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(updatable = false)
private Long id;

...

@Entity
@DiscriminatorValue("DependentCalssChild1")
public class DependentCalssChild1 extends DependentCalss {

private static final long serialVersionUID = 1L;

@ManyToOne
@JoinColumn(name = "child_1_id")
private Child1 child1;
...

DependentCals有两个子类DependentCalsChild1和DependentCalsChild2。

@Entity
@Table(name = "text_id_changed")
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name = "type")
public abstract class DependentCalss implements Serializable {

private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(updatable = false)
private Long id;

...

@Entity
@DiscriminatorValue("DependentCalssChild1")
public class DependentCalssChild1 extends DependentCalss {

private static final long serialVersionUID = 1L;

@ManyToOne
@JoinColumn(name = "child_1_id")
private Child1 child1;
...

及

和JPA假设

@Repository
public interface DependentCalssRepository extends JpaRepository<DependentCalss, Long> {
}

@存储库
公共接口依赖项CALSSrepository扩展了JpaRepository{
}

当我调用DependentCallsRepository的findAll（）时，我捕捉到org.hibernate.PropertyAccessException该字段无法设置，等等

当Child1和Child2在不同的表中具有相同的ID时，就会发生这种情况。

我能做些什么来解决它？由于大量依赖项和约束，我无法更改表中的id。谢谢

您能提供父类的代码吗？已更新。谢谢您能提供父类的代码吗？已更新。谢谢
