先生，我想從數據庫中的數據，並使用HQL不是SQL處於休眠打印和我都試過教程的數量處於休眠打印，但我不能得到正確的答案，請給我提供的解決方案如何從數據庫中獲取數據，並使用HQL

private void pwdActionPerformed(java.awt.event.ActionEvent evt) {          


    Session session = HibernateUtil.getSessionFactory().openSession(); 

    Query query = session.createQuery("FROM Users U WHERE U.pwd='admin'"); 
    List list = query.list(); 

    for (int i = 0; i < list.size(); i++) { 
     System.out.println(list.get(i)); 


    }  

}

先生請儘快

這個問題的回答你的抓取查詢中使用此嘗試。

String hql = "FROM Users U WHERE U.pwd=:pwd"; 
Query query = session.createQuery(hql); 
query.setParameter("pwd","admin"); 
List<User> list = query.list(); 
for (int i = 0; i < list.size(); i++) { 
    System.out.println(list.get(i).getProperty1()); 
    System.out.println(list.get(i).getProperty1()); 
    .... 
    .... 
    System.out.println(list.get(i).getPropertyN()); 
}

getProperty1() ---屬性名稱，比如ID，名稱干將
