Hibernate JPA @QueryHint Example

@QueryHint

The @QueryHint annotation is used to specify a JPA provider hint used by a @NamedQuery or a @NamedNativeQuery annotation.

QueryHint Used to supply a query property or hint to the NamedQuery or NamedNativeQuery annotation.
Vendor-specific hints that are not recognized by a provider are ignored.

        @QueryHint(
            name = "org.hibernate.readOnly",
            value = "true"
        )
