上面是pageShow.ftl 文件这个文件被我进行了些改动，

<!--pageShow 总页数, 当前页, 请求服务地址, 页面大小默认15, 显示最多分页个数, 请求服务地址参数默认为p, 分页样式（可选：gray（默认）、orange、blue）-->        <ul class="fenye">        <#import "pageShow.ftl" as page>        <@page.pageShow totalPage, p, "list?ndid="+ndidVal, size, "gray" ,maxPage/><br/></ul>

controller

//list 文章列表页public void list(){int ndid=this.getParaToInt("ndid");//二级栏目 idQtSecondmenu nd=QtSecondmenu.dao.findById(ndid);//查出二级信息int stid = nd.getInt("st_id");List<QtSecondmenu> ndlist=QtSecondmenu.dao.find("select * from qt_secondmenu where st_id=? ",stid);List<QtIndexlink> indexlink=QtIndexlink.dao.find("select * from qt_indexlink ");//导航int pageNum=this.getParaToInt("pn");System.out.println(pageNum);int pageSize=10;Page<QtArticle> page =QtArticle.dao.queryWebArticle(pageNum,pageSize,ndid);this.setAttr("p", page.getPageNumber());//当前页this.setAttr("size", page.getPageSize());//当前页个数this.setAttr("ndidVal", ndid);//当前页个数this.setAttr("totalPage",page.getTotalPage());//总页数 if(page.getTotalPage() < 10){this.setAttr("maxPage",page.getTotalPage());//最多显示的页数6（1,2,3,4,5,6）}else{this.setAttr("maxPage",10);//最多显示的页数}this.setAttr("arlist", page.getList());//文章信息this.setAttr("ndlist", ndlist);//查出同类型的 二级栏this.setAttr("seleVal", ndid);//把ndid 传到前台，前台判断是否有选中样式this.setAttr("indexlink", indexlink);//导航this.renderFreeMarker("list.html");}

model

//pageNumber,pageSize, 页数 一个几个public Page<QtArticle> queryWebArticle(int pageNum, int pageSize, int ndid) {// TODO Auto-generated method stubtry{String select = "select *   ";String sqlExceptSelect = " from qt_article where nd_id="+ndid+" ";return dao.paginate(pageNum, pageSize, select, sqlExceptSelect);}catch(Exception ex){ex.printStackTrace();return null;}}
