控制层

        PageHelper p = new PageHelper();
        String dev_ = appWordRank.getDev() == null ? "" : appWordRank.getDev();
        String country_ = appWordRank.getCountry()==null?"":appWordRank.getCountry();
        String path = "rank?appid=" + appid + "&dev=" + dev_ + "&country="+country_;
        p.setTotalPage(totalPages);
        p.setPageSize(pageSize);
        p.setPath(path);
        p.setCurrentPage(page);
        model.addAttribute("pager", p.getPageHTML());
