JPA如何使用Order by包含空值

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
import javax.persistence.TypedQuery;
import java.util.List;

public class Main {
    public static void main(String[] args) {
        EntityManagerFactory emf = Persistence.createEntityManagerFactory("your-persistence-unit");
        EntityManager em = emf.createEntityManager();

        String jpql = "SELECT e FROM Entity e ORDER BY e.property NULLS FIRST";
        TypedQuery<Entity> query = em.createQuery(jpql, Entity.class);
        List<Entity> entities = query.getResultList();

        for (Entity entity : entities) {
            System.out.println(entity);
        }

        em.close();
        emf.close();
    }
}
