Java 坎恩'；t从DB hql检索项目

有此代码：

Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
Query query = session.createQuery("from DBUser where id=1");
    for(Iterator it=query.iterate();it.hasNext();){
    Object[] row = (Object[]) it.next();
    System.out.println("ID: " + row[0]);
    System.out.println("Name: " + row[1]);
    System.out.println("Amount: " + row[2]);
}

出现错误：

java.lang.ClassCastException:com.mycompany.app.DBUser无法强制转换为[Ljava.lang.Object；

可能有更简单的方法从表中检索单个元素？

hql在本例中返回映射类型。您的代码应该如下所示：

Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
Query query = session.createQuery("from DBUser where id=1");
    for(Iterator it=query.iterate();it.hasNext();){
    DBUser row = (DBUser) it.next();
    System.out.println("ID: " + row.getId());
    System.out.println("Name: " + row.getName());
    System.out.println("Amount: " + row.getAmount());
}
