在同一张数据库表中使用Map统计数据

管先飞 — Wed, 12 Sep 2012 15:57:00 GMT

1、主要方法：

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

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

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

List titleList = MessageCountService.titleList(); //表列

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

List dataList=MessageCountService.findData(users,messType,startDate,endDate); //数据集
Map 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 titleList(){

List list = new ArrayList();

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 findMentList(UserVO users,String type){

List list = new ArrayList();

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 findData(UserVO users, String messType,String startDate,String endDate){

List list = new ArrayList();

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

list.addAll(reportDataList);

return list;

}

public static Map getReport(List paraList){

Map reportMap = new HashMap();

for(int i=0;i

ReportDataVO p = paraList.get(i);

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

}

return reportMap;

}

3、遍历数据：

Map 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));

}

Struts2转码操作

1、在Struts2对于的action类中：
FlowChart fcName;
URLEncoder.encode(fcName.getFlowChartName(),"UTF-8")
2、在接受页面转码：
String fcName= new String(request.getParameter("fcName").getBytes("ISO-8859-1"),"UTF-8");
3、JavaScript传中文值给Action出现乱码问题解决

new String(newFileName.getBytes("ISO-8859-1"),"UTF-8") ;
多学一点
