EntityGraph 和 LEFT JOIN FETCH 查询的 Hibernate L2 缓存问题

Hibernate L2 cache issues with EntityGraph and LEFT JOIN FETCH queries

我使用 hibernate 5.3.14 和 hazelcast 3.11.5 作为二级缓存提供程序和 spring 启动 2.1.11。

我用关系定义了 3 个实体:

@Entity
@Table(name = "orders")
@org.hibernate.annotations.Cache(usage =CacheConcurrencyStrategy.READ_WRITE)
public class Order extends AbstractBaseEntity implements Orderable {

    @OneToMany(mappedBy = "parent", cascade = CascadeType.ALL)
    @org.hibernate.annotations.Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
    @LazyCollection(LazyCollectionOption.TRUE)
    @Fetch(FetchMode.SELECT)
    private List<OrderItem> orderItems;

@MappedSuperclass
public abstract class AbstractBaseEntity

    @OneToMany(orphanRemoval = true, cascade = CascadeType.ALL)
    @org.hibernate.annotations.Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
    @JoinColumn(name = "parent_rid")
    @LazyCollection(LazyCollectionOption.TRUE)
    private List<CustomField> customFields = new ArrayList<>();

@Entity
@Table(name = "custom_fields")
@org.hibernate.annotations.Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
public class CustomField implements Serializable {

@Entity
@Table(name = "order_items")
@org.hibernate.annotations.Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
public class OrderItem extends AbstractBaseEntity implements Orderable {

我有一个仓库:

@Repository
public interface OrderRepository extends JpaRepository<Order, String> {

    @EntityGraph(attributePaths = "customFields")
    Optional<Order> findById(String rid);

    @QueryHints(value = {@QueryHint(name = "org.hibernate.cacheable", value = "true")})
    @EntityGraph(attributePaths = "customFields")
    @Query("select o from Order left join fetch o.orderItems where o.status = 'ACTIVE' ")
    List<Order> findAllActiveWithOrderItems();

有3个问题:

  1. repo 方法findById 不从缓存中加载主要实体、订单、关系、customFields,由加载的实体图指示

  2. repo 方法 findAllActiveWithOrderItems 的缓存查询结果似乎没有关系,orderItems,由 FETCH JOIN

    加载
  3. 缓存的查询结果 对于 repo 方法 findAllActiveWithOrderItems 似乎没有由 EntityGraph、customFields

    加载的关系

是否有任何已知的休眠问题或解决方法来解决这些问题?

这是一个已知问题,我认为 Hibernate 6.0 会修复它,但我不记得是否有过此问题的票证。
