JPA:如何在设置参数后获取/打印(类型化)查询后面的JPQL查询字符串？

import javax.persistence.EntityManager;
import javax.persistence.Persistence;
import javax.persistence.Query;
import org.eclipse.persistence.internal.jpa.EJBQueryImpl;

public class JPAExample {
    public static void main(String[] args) {
        EntityManager entityManager = Persistence.createEntityManagerFactory("example-unit").createEntityManager();
        entityManager.getTransaction().begin();

        // 创建一个类型化查询
        TypedQuery<ExampleEntity> query = entityManager.createQuery("SELECT e FROM ExampleEntity e WHERE e.name = :name", ExampleEntity.class);

        // 设置查询参数
        query.setParameter("name", "John Doe");

        // 获取查询字符串
        String queryString = ((EJBQueryImpl) query.unwrap(org.eclipse.persistence.queries.DatabaseQuery.class)).getDatabaseQuery().getJPQLString();

        // 打印查询字符串
        System.out.println(queryString);

        entityManager.getTransaction().commit();
        entityManager.close();
    }
}
