page 类

Controller

@RequestMapping(params="findZyxx")
    public String findZyxx(Page page,Model m){

        m.addAttribute("professionList", professionBiz.findAll(page));
        page.setRows( professionBiz.count());
        m.addAttribute("page",page);
        return "view/profession/professioninfo/professioninfo_list";

    }

实现类

 public List<Profession> findAll(Page page) {

         int begin =page.getBegin();
         int end= page.getEnd();

         return professionDao.findPage(begin,end);
     }
