CodePudding user response：

You have to use @JoinColumn to tell JPA that it should us the FK on the CHILD_PRICING table.

For example

@OneToOne
@JoinColumn(name="ID")
private ChildPricing childPricing;

CodePudding user response：

Try with PrimaryKeyJoinColumn :

@Entity
public class ChildPricing {
  @OneToOne
  @PrimaryKeyJoinColumn
  private ParentPrice parentPrice;

  private String priceName;
}
