我想从 sql server 数据库中获取数据,所以我使用 jdbc 驱动程序和 eclipselink orm 框架。我有一些问题。这是我的例子,
public static void main(String[] args)
{
EntityManager entityManager =
Persistence.createEntityManagerFactory("HRPSPU").createEntityManager();
List<Personnel> personnelList = entityManager.createQuery("Select p FROM Personnel p",Personnel.class).getResultList();
for (Personnel personnel : personnelList)
{
System.out.println(personnel.getName());
}
}
和错误,
