分页查询设置每页多少条数据

int pageIndex = request.getParameter("pageIndex") == null ? 1 : Integer.parseInt(request.getParameter("pageIndex"));int pageSize = request.getParameter("pageSize") == null ? 15 : Integer.parseInt(request.getParameter("pageSize"));int start = (pageIndex - 1) * pageSize + 1;int end = pageIndex * pageSize;hashMap.put("start", new Integer(start));hashMap.put("end", new Integer(end));List list = medicalImpl.getMedicalsForNurse(hashMap);String medicalXML = getListToXml(list);//modelView.addObject("medicalXML", medicalXML);之前返回的json包起了responsee.getWriter().print(medicalXML);//改成返回xml，外层不需要json。
