让jsp文本框提交上来值让分页来处理

文本框提交上来的action：

else if(dataUpdateType.equals("dataUpdateQueryButton"))
  {
   HttpSession session = request.getSession();
   session.setAttribute("brandNumberSelect", brandNumberSelect) ;
   session.setAttribute("brandNumberInput", brandNumberInput) ;
   session.setAttribute("brandNumberKind", brandNumberKind) ;
  }
  return mapping.findForward("DataUpdateTurn");

首先判断是点击的是要查询的按钮，然后进到if体里，把从form里取出来的值分别保存给session，然后转到分页的action：

public ActionForward execute(ActionMapping mapping, ActionForm form,
   HttpServletRequest request, HttpServletResponse response) 
 {
  HttpSession session = request.getSession();
  String brandNumberSelect = (String)session.getAttribute("brandNumberSelect") ;
  String brandNumberInput = (String)session.getAttribute("brandNumberInput") ;
  String brandNumberKind = (String)session.getAttribute("brandNumberKind") ;
  
  if(action==null||action.equals("null"))
  {
   list=new DateUpdateSelectListPageBean().findAll(brandNumberSelect,brandNumberInput,brandNumberKind);
  }

在分页action里把session值取出来，然后把session以方法带参数的方式把值给SQL语句所在的方法，也就是下边的业务bean：

public List findAll(String brandNumberSelect,String brandNumberInput,String brandNumberKind) 
 {
  
  List list = new ArrayList();
  ResultSet rs = null;
  final String SQL = "select hphm,hpzl,syr,wfsj,wfdd,wfdm,xh from dzjc_flow where fbbj='1' and clbj='0' and hphm = '"+brandNumberSelect+brandNumberInput+"' and hpzl = '"+brandNumberKind+"' " ;
  System.out.println("DateUpdateSelectListPageBeanSQLL"+SQL);
  try 
  {
   rs = PageDBConnection.getResultSet(SQL);
   while (rs.next()) 
   {
    DateUpdateSelectVo dateUpdateSelectVo = new DateUpdateSelectVo();
    //这个顺序控制分页jsp显示的顺序
    dateUpdateSelectVo.setHphm(rs.getString(1));
    dateUpdateSelectVo.setHpzl(rs.getString(2));
    dateUpdateSelectVo.setSyr(rs.getString(3));
    dateUpdateSelectVo.setWfsj(rs.getString(4));
    dateUpdateSelectVo.setWfdd(rs.getString(5));
    dateUpdateSelectVo.setWfdm(rs.getString(6));
    dateUpdateSelectVo.setXh(rs.getString(7));
    list.add(dateUpdateSelectVo);

   }
  } 

这样SQL语句就得到了文本框输入的值了，这样再用jsp里的.do开始执行分业的功能，到了查询数据库的时候就会按照文本框输入的值来查询了
