小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
大家好：
????? 今天遇到一個問題自己整了一下午，好不容易整理出來，跟大家一起分享一下！樣式如下：
JSP頁面 其中
<span style="font-size:14px;"><%@ page language="java" contentType="text/html; charset=UTF-8"pageEncoding="UTF-8"%>
<%@ include file="/view/common/tags.jsp" %>

<title>交易記錄</title>
</head>
<body>
<input type="hidden" id="currentPage" name="currentPage" value="0" /><div class="container"><ul class="record_tab"><li class="current" οnclick="clickMother(30)">近一個月</li><li οnclick="clickMother(90)">近三個月</li><li οnclick="clickMother(0)">全部</li></ul><div class="panes"></div>
</div>
<script type="text/javascript" src="<%=request.getContextPath()%>/js/jquery-1.11.1.min.js"></script>
<script type="text/javascript">$(function(){?? ?$('.record_tab li').click(function(){?? ??? ?$(this).addClass('current').siblings().removeClass('current');$('.panes>div:eq('+$(this).index()+')').show().siblings().hide();?? ?})});

//分頁顯示

Controller 方法：
@RequestMapping(value = "/transactionRecords", method = RequestMethod.POST)@ResponseBodypublic Object transactionRecords(@RequestParam(value = "cardno", required = true) String cardno //京醫通卡號,@RequestParam(value = "startDate", required = true) String startDate //開始時間,@RequestParam(value = "endDate", required = true) String endDate //結束時間,@RequestParam(value = "currentPage", required = false) String currentPage //當前頁數的起始條數){CardInfo cardInfo = new CardInfo();String inputType = "5"; //操作類型 5.交易記錄查詢cardInfo.setCardno(cardno); //卡號List<TradeRecords> tradeRecordsList = null;try {//分頁參數Integer pageSize =5;Integer curPage =(Integer.parseInt(currentPage)-1)*pageSize;Map<String, Object> pageInfo = new HashMap<String,Object>();pageInfo.put("curPage", curPage); //當前頁數的起始條數pageInfo.put("pageSize", pageSize); //每頁多少條tradeRecordsList = cardManageInf.queryTradeRecords(cardInfo, inputType, startDate, endDate, pageInfo); //根據京醫通卡號，查詢交易記錄} catch (Exception e) {e.printStackTrace();logger.error("接口調用異常！");}return tradeRecordsList;}
Service 分頁方法
@Overridepublic List<TradeRecords> queryTradeRecords(CardInfo cardInfo,String inputType,String startDate, String endDate,Map<String, Object> pageInfo) throws Exception {List<TradeRecords> tradeRecordsList = new ArrayList<TradeRecords>(); //所有數據List<TradeRecords> tradeRecordsList1 = new ArrayList<TradeRecords>(); //當前頁數據for (int i = 0; i < 8; i++) {TradeRecords tradeRecords = new TradeRecords();tradeRecords.setTradeNo("abc000001"+String.valueOf(i));tradeRecords.setTradeType("交易類型"+String.valueOf(i));tradeRecords.setTradeTime("2015-01-03");tradeRecords.setTradePlace("協和醫院");tradeRecords.setClientType("正常繳費");tradeRecords.setAmount(100d);tradeRecordsList.add(tradeRecords);}int curPage = (int) pageInfo.get("curPage"); //當前條數從哪里開始取int offset = tradeRecordsList.size()-curPage;//還有多少沒有取過int pageSize = (int) pageInfo.get("pageSize"); //每頁顯示的記錄數int pageCount = offset>pageSize?pageSize : offset;//如果沒有取過的大于需要顯示的數，則實現顯示數pageCount=pageItems,反之然；即剩余數大于顯示條數，則顯示五條，否則顯示剩余條數for(int i=curPage;i<tradeRecordsList.size();i++){tradeRecordsList1.add(tradeRecordsList.get(i));if(tradeRecordsList1.size() == pageCount){break;}}return tradeRecordsList1;}
