I have a application which all database tables have a column named BRAND and this column is in PRIMARY KEY.
In table of Customer, I have a column id (autoincremnt), that together with brand make a composite key, mapping to Java entity as follows:
@Entity
@Table(name = "CUSTOMERS")
public class CustomerEntity implements Serializable {
@EmbeddedId
private CustomerId id;
//getters and setters and other attributes hidden
}
@Embeddable
public class CustomerId implements Serializable {
@Column(name = "BRAND")
private String brand;
@Column(name = "ID_CUSTOMER")
private String idCustomer;
//getters and setters hidden
}
The issue is on mapping of the Customer entity to be foreign key of the Order entity.
@Entity
@Table(name = "ORDERS")
public class OrderEntity implements Serializable {
@EmbeddedId
private OrderId id;
@Column(name = "STATUS")
private Integer status;
@Column(name = "DELIVERY_DATE")
private LocalDateTime deliveryDate;
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumns(value = {
@JoinColumn(name = "ID_CUSTOMER", referencedColumnName = "ID_CUSTOMER", updatable = false, insertable = false),
@JoinColumn(name = "BRAND", referencedColumnName = "BRAND", updatable = false, insertable = false)})
private CustomerEntity customer;
}
@Embeddable
public class OrderId implements Serializable {
@Column(name = "ID_ORDER")
private String idOrder;
@Column(name = "BRAND")
private String brand;
}
This way, I am able to read the orders and bring the customer together through the call to orderRepository.findAll().
However, when I save a new order, passing the existing customer to the order entity, the customer is not saved in the order through the call to orderRepository.save(order).
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumns(value = {
@JoinColumn(name = "ID_CUSTOMER", referencedColumnName = "ID_CUSTOMER"),
@JoinColumn(name = "BRAND", referencedColumnName = "BRAND")})
private CustomerEntity customer;
I get the following Exception:

BRAND | ID_ORDER | ID_CUSTOMER | STATUS | DELIVERY_DATE
What is the correct way for mapping Customer (a composite foreign key) in Order class?
I see multiple issues:
Why the idCustomer attribute is a String. Shouldn't it be a Long or an Integer if it's an AUTO_INCREMENTED column?
You didn't show the code to save the Customer info into your Order, but the problem is that you used updatable = false, insertable = false which should be used only when you duplicate the mapping, like when the customer id is contained in the Order PK. Just change the mapping to:
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumns(value = {
@JoinColumn(
name = "ID_CUSTOMER",
referencedColumnName = "ID_CUSTOMER"
),
@JoinColumn(
name = "BRAND",
referencedColumnName = "BRAND",
insertable = false,
updatable = false
)
})
private CustomerEntity customer;
, and everything should work just fine.
customer association since it can be a major cause of performance issues and lead to N+1 query issues.
