Code generation for JPA 2.0 uses old features
---------------------------------------------
Key: JBIDE-7568
URL:
https://jira.jboss.org/browse/JBIDE-7568
Project: Tools (JBoss Tools)
Issue Type: Bug
Components: Hibernate
Affects Versions: 3.2.0.Beta1
Reporter: Juergen Zimmermann
Assignee: Max Andersen
When choosing JPA 2.0 for code generation, then @OneToMany and @ManyToOne still generates
relationships as in JPA 1.0. But the JPA 2.0 style is definitely better esspecially when
it comes to unidirectional relationships where you just want to delete one side of the
bidirectional relationship.
Example: one customer has many orders
@Entity
@Table(name = "customer")
public class Customer implements Serializable {
...
@OneToMany
@JoinColumn(name = "customer_fk") // foreign key in table "order"
private Set<Order> orders;
@Entity
@Table(name = "order")
public class Order implements Serializable {
...
@ManyToOne
@JoinColumn(name = "customer_fk", insertable = false, updatable = false)
private Customer customer;
As you can see: the foreign key is declared at both sides of the relationship so that one
side can easily ommitted to just have a unidirectional relationship.
