在hibernate-5中运行命名查询时，如何确保它使用的是JPA2.1标准

<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence
                                 http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd"
             version="2.1">
    <!-- 配置持久化单元等信息 -->
</persistence>

@Entity
@NamedQuery(name = "findUserByName", query = "SELECT u FROM User u WHERE u.name = :name")
public class User {
    // 实体类定义
}

EntityManager entityManager = entityManagerFactory.createEntityManager();
Query query = entityManager.createNamedQuery("findUserByName");
query.setParameter("name", "John Doe");
List<User> users = query.getResultList();
