GAT專案新需求：ETC管理增加查詢統計
需求：按車牌號HOST_NO分組合計CAR_PAY金額，最後合計所有金額，還要過濾出本月的時間
因為要顯示明細，不是真的group by分組，而是按車牌號排序
消費合計和合計則是這種格式，前臺需要這樣的格式方便展示：

只不過是在程式碼中拼出消費合計和合計的列
-------------------------------------------------------------------------------------------------------------------------------
下面看程式碼：
關鍵是要動態增加索引，這樣才可以在每個車牌號下增加消費合計的一列
@SuppressWarnings("unchecked")
@Override
public ListResp queryCarUseEtcListTotal(CarUseEtcListReq req) throws Exception{
ListResp resp = new ListResp();
List<CarUseEtcListResp> list = new ArrayList<CarUseEtcListResp>();
long begin = System.currentTimeMillis();
list = carUseEtcDAO.queryCarUseEtcListTotal(req);
//儲存有序的車牌號
List<String> listTemp = new ArrayList<String>();
//儲存車牌號，隨著list中的車牌號索引的增加而增加
List<String> noList = new ArrayList<String>();
if(Util.isNotEmpty(list)){
for(int i=0;i<list.size();i++){
if(!listTemp.contains(list.get(i).getCarHostNO())){
listTemp.add(list.get(i).getCarHostNO());
}
noList.add(list.get(i).getCarHostNO());
}
}
//總的合計
Double total = 0.0;
if(Util.isNotEmpty(listTemp)){
for (String cardNo : listTemp) {
//相同車牌號的消費合計
Double num = 0.0;
for(int i=0;i<list.size();i++){
CarUseEtcListResp one = list.get(i);
if(Util.isNotEmpty(one) && Util.isNotEmpty(one.getCarHostNO())){
if(one.getCarHostNO().equals(cardNo)){
num += one.getCarPay();
}
}
}
CarUseEtcListResp beanC = new CarUseEtcListResp();
//得到noList集合中車牌號的索引
Integer a = noList.lastIndexOf(cardNo);
//消費合計的金額
beanC.setCarPay(num);
//給前臺的文字"消費合計",頁面放在省份列表下了
//beanC.setCarProvince("消費合計");
beanC.setCarProvinceDesc("消費合計");
//在需要的索引下增加一列
list.add(a+1, beanC);
//noList集合也增加索引
noList.add(a+1,beanC.getCarHostNO());
//總的合計
total += num;
}
}
CarUseEtcListResp bean = new CarUseEtcListResp();
//給前臺的文字"合計",頁面放在ETC卡號列表下了
bean.setCarEtcNo("合計");
//合計的金額
bean.setCarPay(total);
list.add(list.size(),bean);
//System.out.println(sumCarPay + "," + total);
boolean isDebug = log.isDebugEnabled();
if(isDebug) {
log.debug("資料庫查詢耗時 " + (System.currentTimeMillis() - begin) + " ms");
}
if(!Util.isEmpty(list)){
begin = System.currentTimeMillis();
DictionaryUtil.translate(list);
resp.getList().addAll(list);
if(isDebug) {
log.debug("結果集轉換耗時 " + (System.currentTimeMillis() - begin) + " ms");
}
}
return resp;
}
