如何在hibernate中进行两个具有组合键的表之间的一一映射？

@Embeddable
public class CompositeKey implements Serializable {
    private String keyPart1;
    private String keyPart2;
    
    // getters and setters
}

@Entity
public class MainEntity {
    @EmbeddedId
    private CompositeKey compositeKey;
    
    // other properties
    
    @OneToOne
    @MapsId
    @JoinColumn(name = "compositeKey", referencedColumnName = "keyPart1")
    private RelatedEntity relatedEntity;
    
    // getters and setters
}

@Entity
public class RelatedEntity {
    @Id
    private String keyPart1;
    
    // other properties
    
    @OneToOne(mappedBy = "relatedEntity")
    private MainEntity mainEntity;
    
    // getters and setters
}
