unidirectional One-To-Many association error using Spring, Hibernate, Postgres - spring

Question

I have a unidirectional one-to-many association between my customer class:
#Entity
public class Customer
{
#Id
private String username;
private String password;
private String email;
private String address;
//Customer Associations
#OneToMany
#JoinColumn
private List<Commission> commission;
public void setOrder(List<Commission> commission) {
this.commission = commission;
}
public List<Commission> getOrder() {
return commission;
}
and my Commission class:
#Entity
#Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
public abstract class Commission
{
#Id
private int confirmationNumber;
private int totalCost;
}
, that has two subclasses PickupCommission:
#Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
#Entity
public class PickupCommission extends Commission
{
public enum PaymentMethod { CreditCard, Cash }
#Enumerated
#Column(nullable = false)
private PaymentMethod paymentMethod;
//PickupOrder State Machines
public enum PickupStatus { InCart, Ordered, Prepared, PickedUp }
#Enumerated
#Column(nullable = false)
private PickupStatus pickupStatus;
}
and DeliveryCommission. After resetting my database, upon building, it gives these warnings that the constraint is not satisfied

In my controller, when I create a PickupCommission, I create it, then I add it to the Customer commissions list as such:
#CrossOrigin(origins = "*")
#RestController
public class PickupOrderRestController {
#PostMapping(value = { "/pickupOrder", "/pickupOrder/" })
public PickupOrderDTO createPickupOrder(#RequestParam String username, #RequestParam String paymentMethod, #RequestParam String accountType) throws IllegalArgumentException {
System.out.println("1");
PickupCommission p = service.createPickupOrder(username, paymentMethod, accountType);
System.out.println("2");
System.out.println(customerService.getCustomerOrders(username));
System.out.println("3");
if (accountType.equals("Customer")) customerService.addOrder(username ,p);
System.out.println("4");
return convertToDto(p);
}
It prints all the way to 3, finishes the addOrder function, but leaving the add order function, raises the following error and does not print 4

I have tried changing serveral other functions in the process when it was creating the pickup order, but it really seems to be a problem with adding it to the list. Right now I am thinking that it as problem with the JPA tag choice for the associations thats making it not be modifiable like this.

Answer 1

Figured it out, it's because it was only a one way association; made it bidirectional with a mapped by, when i create a commission now, it gets a customer added to it, and it gets added to the customers list of commissions
