JPA Annotation Attribute in javax.persistence. ManyToOne Class targetEntity default void.class (Optional) The entity class that is the target of the association. Defaults to the type of the field or property that stores the association. Since: JPA 1.0

JPA Annotation Attribute in javax.persistence. ManyToOne CascadeType [] cascade default {} (Optional) The operations that must be cascaded to the target of the association. By default no operations are cascaded. Since: JPA 1.0

JPA Annotation Attribute in javax.persistence. ManyToOne FetchType fetch default EAGER (Optional) Whether the association should be lazily loaded or must be eagerly fetched. The EAGER strategy is a requirement on the persistence provider runtime that the associated entity must be eagerly fetched

JPA Annotation Attribute in javax.persistence. ManyToOne boolean optional default true (Optional) Whether the association is optional. If set to false then a non-null relationship must always exist. Since: JPA 1.0

Hi! I have 2 entities: User and Item, both @Cacheable. Item has @ ManyToOne private User user.
