page 类

package org.lq.ssm.page;

public  class Page {
    
        // 分页时输入的参数
        private int currentPage = 1; // 当前页码
        private int pageSize = 10; // 每页显示的行数

        // 写分页SQL时需要的条件，由输入参数计算而来
        private int begin; // 当前页的起始值
        private int end; // 当前页的终止值
        

        // 用于计算总页数
        private int rows; // 总行数

        // 总页数，由rows和pageSize计算而来
        private int totalPage;

        public int getBegin() {
            begin = (currentPage - 1) * pageSize;
            return begin;
        }

        public int getEnd() {
            end = currentPage * pageSize + 1;
            return end;
        }

        public int getTotalPage() {
            if(rows==0){

        public void setCurrentPage(int currentPage) {
            this.currentPage = currentPage;
        }

        }
    

}

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);
    }

mapper文件中sql

 <select id="findPage" resultMap="profession_map">
       
        select * from (select a.*,rownum r from ( select * from zyml_table ) a) where r  &lt; #{end} and r &gt; #{begin}
      <!--  select * from zyml_table -->
