struts+spring+hibernate的web应用（4.1）

 Web层代码编写：

 我们还是先从主要的 action 开始吧。

在 com.game.products.web.actions 包中新建 ProductsAction ，这是一个 DispatchAction ，代码如下：

 

package com.game.products.web.actions;

 import  java.util.List;

 import  javax.servlet.http.HttpServletRequest;
 import  javax.servlet.http.HttpServletResponse;

 import  org.acegisecurity.AccessDeniedException;
 import  org.apache.struts.action.ActionForm;
 import  org.apache.struts.action.ActionForward;
 import  org.apache.struts.action.ActionMapping;
 import  org.apache.struts.actions.DispatchAction;

 import  com.game.commons.Pager;
 import  com.game.commons.PagerService;
 import  com.game.products.model.Products;
 import  com.game.products.services.iface.ProductsService;
 import  com.game.products.web.forms.ProductsForm;


 public   class  ProductsAction  extends  DispatchAction   {

     private  ProductsService productsService;
     private  PagerService pagerService;

         int  totalRows = productsService.getRows();
        String currentPage = req.getParameter( " currentPage " );
        String pagerMethod = req.getParameter( " pagerMethod " );

        Pager pager = pagerService.getPager(currentPage, pagerMethod, totalRows);
