struts(包括动态验证)&Hibernate的事例(增(可添加中文信息)/删/改)

java 代码

 struts action中的部分代码:
int uid=Integer.parseInt(request.getParameter("id"));
 UserDAO dao=UserDAO.getInstance();
 returnUser=dao.getAllUsers(uid);
 request.setAttribute("user", returnUser);

 return new ActionForward("/update.jsp");
}

public ActionForward update(ActionMapping mapping, ActionForm form,
  HttpServletRequest request, HttpServletResponse response) {
 AddForm addForm = (AddForm) form;
 int uid=Integer.parseInt(request.getParameter("id"));
 String username=addForm.getUsername();
 String password=addForm.getPassword();
 String qq=addForm.getQq();
 UserDAO dao=UserDAO.getInstance();
 dao.updateUser(uid, username, password, qq);

 return new ActionForward("/index.jsp" );
这是DAO方法中的部分代码:
public List getAllUsers(){

  List list=null;
  Transaction tx=null;

  Session session=HibernateSessionFactory.getSession();
  tx=session.beginTransaction();
  Query query=session.createQuery("from Users u");
  list=query.list();
  tx.commit();
  session.close();

  return list;
 }

 public Users getAllUsers(int id){

  Transaction tx=null;
  Users getUser=new Users();

  Session session=HibernateSessionFactory.getSession();
  tx=session.beginTransaction();
  getUser=(Users)session.createQuery("from Users u where id=?").setInteger(0, id).uniqueResult();
  tx.commit();
  session.close();

  return getUser;
 }
