Say I have the following entities
{noformat}User {
@Id
id: String
name: String
}
Order {
@Id
id: String
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn
user: User
// Meant to be different from Order.user
// This extra field makes Hibernate use several queries when fetching which then leads to this bug
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn
targetUser: User
@OneToMany(targetEntity=OrderItem.class, mappedBy="order", fetch=FetchType.EAGER)
orderItems: Set<OrderItem>
}
OrderItem {
@Id
id: String
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn
order: Order
// Same as Order.user
// Note that unlike Order.user, here it is LAZY
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn
user: User
}{noformat}
Fetching a single entity works well and returns an Order with all the relationships populated. But fetching multiple entities returns Order with Order.user not initialised.
This issue is present with - and without - bytecode enhancement.
-I’ll add a PR with a test case shortly.- - done |
