分页问题

Question

 <%  
                   String currPage = request.getParameter("currPage"); //获得当前页数
                   int iCurrPage = 1 ;                                 //定义目前的页数，注意初始值不能为“0”
                   int pages = 1 ;                                     //定义总页数。
                   int allRecCount = 0 ;                               //定义表中总的记录数
                   int recPerPage = 5 ;                                //定义每页显示的记录数

              <%}%>
String currPage = request.getParameter("currPage");里的currPage一般写在哪里呢 不用写出来吗  这是这个JSP页面的部分代码  我没找到currPage分页JSP

具体项目实例可以参考我的博客,基于spring,security,struts开源
里面有分页方案,仅供参考

Answer 2

                  if(currPage != null && !currPage.equalsIgnoreCase("")){ //判断currpage是否为空
                   iCurrPage = Integer.parseInt(currPage);               //将currpage赋值给iCurrpage
                  }
                  List listMeeting =HibernateUtil.finMeeting((iCurrPage - 1) * recPerPage, recPerPage);  //调用分页方法
                   if(listMeeting.isEmpty()){
               out.println("暂无信息");                         //如果查询结果为空时，页面输出"暂无信息"
            }
楼主看这个。是传到后台的。

我没有写在jsp过.我们一般都写一个pageDao通用分页来做.只要继承他就行了.你说的那个currPage应该在Action里.因为你写页面分页还是要到Action里处理的.
