spring data jpa - EmbeddedId not in sync with relationship

Question

I have the below data structure, I have a doubt regarding having the embedded id in sync with mapped data.

@Data
@Builder
public class Product{

  @Embedded
  private ProductId productId;

  @ManyToOne(fetch = FetchType.EAGER)
    @MapsId("locationId")
    private Location location;
  
}

@Embeddable
public class ProductId{
  @Column(name="item_id")
  private Integer id;

  @Column(name="location_id")
  private Integer locationId;
  
  
}

How would i keep the field location in sync with locationId in ProductId or vice versa. Should I write custom setters to set values for embedded id when setting value for location?
