mysql mybatis springmvc 分页

由于工作需要，需要mysql mybatis springmvc 分页，

if(null!=request.getParameter("rows")){//每页行数

pwhere.setPageSize(Integer.parseInt(request.getParameter("rows")));

}

if(null!=request.getParameter("page")){//当前页

int page=(Integer.parseInt(request.getParameter("page"))-1)*pwhere.getPageSize();

pwhere.setPage(page);

}
