在同一张数据库表中使用Map统计数据

在同一张数据库表中使用Map统计数据

1、主要方法：

               String startDate = req.getParameter("startDate"); 

String endDate = req.getParameter("endDate");

UserVO users = (UserVO) req.getSession().getAttribute("users");

List<ReportBaseVO> titleList = MessageCountService.titleList();  //表列

List<ReportBaseVO> mentList=MessageCountService.findMentList(users,messType); //表行

                List<ReportDataVO> dataList=MessageCountService.findData(users,messType,startDate,endDate); //数据集
Map<String,String> dataMap = ReportService.getReport(dataList); //装入Map
2、方法实现：
//0：满意 1：非常满意2：不满意 

public static List<ReportBaseVO> titleList(){

List<ReportBaseVO> list = new ArrayList<ReportBaseVO>();

ReportBaseVO vo1 = new ReportBaseVO();

vo1.setCode("0");

vo1.setName("满意");

list.add(vo1);

ReportBaseVO vo2 = new ReportBaseVO();

vo2.setCode("1");

vo2.setName("基本满意");

list.add(vo2);

ReportBaseVO vo3 = new ReportBaseVO();

vo3.setCode("2");

vo3.setName("不满意");

list.add(vo3);

return list;

}

public static List<ReportBaseVO> findMentList(UserVO users,String type){

List<ReportBaseVO> list = new ArrayList<ReportBaseVO>();

         

if((users.isHave("0") && ("1".equals(type)||type==null||"".equals(type)))||users.isHave("1") && ("1".equals(type)||type==null||"".equals(type))){

ReportBaseVO vo1 = new ReportBaseVO();

vo1.setCode("1");

vo1.setName("局长信箱");

list.add(vo1);

}

}

public static List<ReportDataVO> findData(UserVO users, String messType,String startDate,String endDate){

               List<ReportDataVO> list = new ArrayList<ReportDataVO>();

String sql="select APPRAISAL as titleId,MESS_TYPE as mentId,count(ID) as count from act_message where DELETE_FLAG='0' and APPRAISAL<>'' and MESS_TYPE='1' group by MESS_TYPE,APPRAISAL";

List<ReportDataVO> reportDataList = DBBeanUtil.execute(conn, new ReportDataVO(),sql);

list.addAll(reportDataList);

return list;

}

public static Map<String,String> getReport(List<ReportDataVO> paraList){

Map<String, String> reportMap = new HashMap<String, String>();

for(int i=0;i<paraList.size();i++){

ReportDataVO p = paraList.get(i);

reportMap.put(p.getMentId()+"_"+p.getTitleId(), String.valueOf(p.getCount()));

}

return reportMap;

}

3、遍历数据：

Map<String,String> dataMap = ReportService.getReport(dataList);

String[][] data = new String[mentList.size()][titleList.size()];

for (int i = 0; i < mentList.size(); i++) {

mentList.get(i).getName();  

int typeAll=0;

for (int j = 0; j < titleList.size(); j++) {

String dateMa=mentList.get(i).getCode()+ "_" + titleList.get(j).getCode();

//             out.print("titleList.get(j).getCode():"+titleList.get(j).getCode());

String content = dataMap.get(dateMa);//IsTurn0

if (content == null || "".equals(content)) {

content = "0";

}

data[i][j] = content;

typeAll=Integer.parseInt(content)+typeAll;

}

BigDecimal point = new BigDecimal(0);

BigDecimal mcount=new BigDecimal(data[i][0]).add(new BigDecimal(data[i][1]));//满意发布件数

BigDecimal atotal=mcount.add(new BigDecimal(data[i][2]));//共发布件数

if(atotal.compareTo(new BigDecimal(0))!=0){

point = new BigDecimal(100).multiply(mcount.divide(atotal,2, RoundingMode.HALF_UP));

}

}
