У меня есть две @OneToMany аннотации в одном классе.Это работает нормально, когда я сохраняю адрес, но для заказа я получаю сообщение об ошибке с sql.
Я нашел решение, где они сказали использовать set, и попытка, которая также не помогла.
@Entity
public class Customer {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Integer customerId;
@OneToMany(fetch=FetchType.LAZY, mappedBy="customer", cascade=CascadeType.ALL)
private Set<Order> order;
@OneToMany(fetch=FetchType.LAZY, mappedBy="customer", cascade=CascadeType.ALL)
private Set<Address> address;
public Set<Order> getOrder() {
return order;
}
public Set<Address> getAddress() {
return address;
}
public void addAddress(Address tempAddress) {
if(address == null) {
address = new HashSet<>();
}
address.add(tempAddress);
tempAddress.setCustomer(this);
}
public void addOrder(Order theOrder) {
if(order == null) {
order = new HashSet<>();
}
order.add(theOrder);
theOrder.setCustomer(this);
}
}
здесь @ ManyToOne с другой стороны отношения
@Entity
public class Address {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Integer addressId;
private String state;
@ManyToOne(fetch=FetchType.LAZY,cascade = {CascadeType.DETACH, CascadeType.MERGE, CascadeType.PERSIST, CascadeType.REFRESH} )
@JoinColumn(name="customer_id")
private Customer customer;
}
@Entity
public class Order {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Integer orderI;
@ManyToOne(fetch=FetchType.LAZY, cascade = {CascadeType.DETACH, CascadeType.MERGE, CascadeType.PERSIST, CascadeType.REFRESH})
@JoinColumn(name="customer_id")
private Customer customer;
}
Когда я сохраняю адрес, он работает нормально, но когда дело доходит до сохраняющегося порядка, я получаю следующую ошибку:
Hibernate: select customer0_.customer_id as customer1_1_0_, customer0_.contact_number as contact_2_1_0_, customer0_.email as email3_1_0_, customer0_.first_name as first_na4_1_0_, customer0_.last_name as last_nam5_1_0_, customer0_.password as password6_1_0_ from customer customer0_ where customer0_.customer_id=?
