Loading entity the below entity with {{OrderItem.withAll}}` fetch graph is ignored. Tested with a singular primary key. It is fine. It seems to fail only with a composite primary key. I attached an example maven project.
{code:java}@Entity
@Table(name = "orderItem")
@IdClass(OrderItem.PK.class)
@NamedEntityGraph(
name = "OrderItem.withAll",
attributeNodes = {
@NamedAttributeNode("product"),
@NamedAttributeNode("order"),
}
)
public class OrderItem {
@Id
@ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "product_id")
private Product product;
@Id
@ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "order_id")
private Order order;
// getters, setters ommited
public static class PK implements Serializable {
private Long product;
private Long order;
@Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
PK pk = (PK) o;
return Objects.equals(product, pk.product) && Objects.equals(order, pk.order);
}
@Override
public int hashCode() {
return Objects.hash(product, order);
}
}
}{code} |
