Hi all,
I have problem with cascading persistence with the following code consisting of 2 annotated classes
Listing and
ListingLocation.
if a
Listing instance is set to the
listing2 of a
ListingLocation instance, the Listing instance will be automatically persisted when I save the
ListingLocation instance
if a
Listing instance is only set to the
listing1 of a
ListingLocation instance, the
Listing instance will NOT be automatically persisted when I save the
ListingLocation instance
listing1 is also used as the primary and foreign key.
Would any one please tell me how should I code to get
listing1 to automatically get persisted?
Thank you very much.
Code:
@Entity
@Table
@Access(AccessType.FIELD)
public class Listing implements Serializable {
@Id
@GeneratedValue
private long id;
@Column(columnDefinition = "DECIMAL(10,2)")
private double price;
...}
Code:
@Entity
@Table
@Access(AccessType.FIELD)
public class ListingLocation implements Serializable {
@Id
@OneToOne()
@Cascade(value={ CascadeType.PERSIST, CascadeType.SAVE_UPDATE })
@ForeignKey(name = "FK_ID")
@JoinColumn(name = "ID", referencedColumnName = "id", unique = true, updatable = false, insertable = false)
private Listing listing1;
@Column(name = "address")
private String address;
@OneToOne()
@Cascade(value={ CascadeType.PERSIST, CascadeType.SAVE_UPDATE })
@JoinColumn(name = "List2", referencedColumnName = "id", nullable = true)
private Listing listing2;
...}
