二次 开发！！！！
看着别人写的像肥肠一样的代码，我失眠了！！
一个分页查询Action里的代码贴出来，留作纪念。
public class supplierMakeOrder extends Action {
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest req, HttpServletResponse resp) throws Exception {
HttpSession session = req.getSession();
User loginUser = (User) session.getAttribute("loginUser");
String username = loginUser.getUserName();
// System.out.println(username);
SearchInvoiceActionForm searchinvoiceForm = (SearchInvoiceActionForm) form;
String forward = "Success";// 下一步的链接
if (loginUser == null) {
forward = "outdate";
} else {
int newPageNo = searchinvoiceForm.getNewPageNo();
req.setAttribute("currentPage", new Integer(newPageNo));
int pageSize = searchinvoiceForm.getPageSize();
pageSize = 10;
if (pageSize == 0) {
PageCt pageCt = new PageCt();// 取得页面大小
pageSize = pageCt.getInt_num();
}
req.setAttribute("pageSize", new Integer(pageSize));
// System.out.println(forward);
String orderStates = searchinvoiceForm.getOrderStates();
String queryBasis = searchinvoiceForm.getQueryBasis();
String queryCond = searchinvoiceForm.getQueryCond();
String orderCond = searchinvoiceForm.getOrderCond();
String cz[] = searchinvoiceForm.getCz();
if (queryCond == null) {
queryCond = queryCond;
} else {
queryCond = queryCond.trim();
}
if (orderCond == null || orderCond.equals(""))
orderCond = " id DESC ";
System.out.println(orderCond);
if ("EBELN".equals(queryBasis)) {
queryBasis = "SAP_EKPO.EBELN";
}
String sql = "";
String countSql = "";
// 订单状态为空
if (queryCond == null || queryCond.trim().length() <= 0)// 没有参数
