一、UserAction中获取到的ArrayList对象填充到UserForm中，jsp页面获取UserForm的初始值。
UserAction的部分代码：
代码如下:
private ActionForward executeManageAction(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
UserForm userForm = (UserForm)form;
ArrayList userlist = new ArrayList();
SessionFactory sf= new Configuration().configure().buildSessionFactory();
Session session=sf.openSession();
Transaction tx=session.beginTransaction();
String sqlQuery="from User";
Query lQuery=session.createQuery(sqlQuery);
userlist=(ArrayList)lQuery.list();
tx.commit();
session.close();
userForm.setUserlist(userlist);
return mapping.findForward("main_user");
}
UsrForm的部分代码：
代码如下:
private ArrayList userlist;
public ArrayList getUserlist(){
return userlist;
}
public void setUserlist(ArrayList userlist){
this.userlist=userlist;
}
JSP页面代码：
代码如下:
二、UserAction中获取到数据ArrayList对象后，把ArrayList对象存在request中，JSP页面在获取到ArrayList对象。
UserAction部分代码：
代码如下:
private ActionForward executeManageAction(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
UserForm userForm = (UserForm)form;
ArrayList userlist = new ArrayList();
SessionFactory sf= new Configuration().configure().buildSessionFactory();
Session session=sf.openSession();
Transaction tx=session.beginTransaction();
String sqlQuery="from User";
Query lQuery=session.createQuery(sqlQuery);
userlist=(ArrayList)lQuery.list();
tx.commit();
session.close();
request.setAttribute("userlist", userlist);
return mapping.findForward("main_user");
}
JSP部分代码：
代码如下:
