学生信息列表

点击学生列表选项，系统通过studentServlet里面的studentList方法查询学生数据，返回给前端student_list.jsp中进行遍历显示

//管理员修改个人信息protected void studentList(HttpServletRequest request, HttpServletResponse response) throws Exception {//跳转到添加用户界面String p=request.getParameter("p");//接收页码System.out.println(p);int pageSize=6;//每页显示5条int pageNum=1; //默认第一页if(p!=null){pageNum= Integer.parseInt(p);}//调用分页查询List<Student> list=ss.getStudentPage(pageNum,pageSize);//携带参数到页面request.setAttribute("list",list); //绑定参数int nums=ss.queryStudentCount(); //查询总数//计算总页数int totalPage=(nums%pageSize==0)? (nums/pageSize):(nums/pageSize+1);request.setAttribute("cp",pageNum); //当前页request.setAttribute("tp",totalPage); //总页数//条件值1：值2request.getRequestDispatcher("/WEB-INF/views/student/student_list.jsp").forward(request,response); //页面转发}
