hibernate根据id查找

/**根据id查找*/

public static User1 query(String id) {  User1 u = null;  try {   session = HibernateSessionFactory.getSession();   Transaction tran = session.beginTransaction();   u = (User1) session.get(User1.class, id);   session.get(User1.class, id);//get()方法也会产生查询语句   tran.commit();  } catch (Exception e) {   e.printStackTrace();  } finally {   HibernateSessionFactory.closeSession();  }  return u; }
