工作中遇到 分页导出（周五）数据表格，导出一个时段的周五的数据，分页sheet表单和对应的列表。一段时间内每个周五在Excel中生成列表中的一条数据和一个表格。
这里主要的记录一下分页sheet表单功能。
public static void main(String[] args) throws Exception {
/*
* 分sheet导出查询记录
*/
List<TimeDay> foolist=getStudentInfo();
String templateDir = "src/main/java/templates/formInfoTemplate_outout.xls";
String targetDir="e:/excel/export/testMultipleSheets.xls";
List sheetNames = new ArrayList();
for(int i=0;i<foolist.size();i++){
TimeDay sa = (TimeDay)foolist.get(i);
sheetNames.add(sa.getEveryFriday());
}
InputStream is = new BufferedInputStream(new FileInputStream(templateDir));
XLSTransformer transformer = new XLSTransformer();
HSSFWorkbook resultWorkBook = null;
try {
resultWorkBook = (HSSFWorkbook) transformer.transformMultipleSheetsList(is, foolist, sheetNames, "TimeDay", new HashMap(), 0);
} catch (InvalidFormatException e) {
e.printStackTrace();
}
OutputStream os = new BufferedOutputStream(new FileOutputStream(targetDir));
try {
resultWorkBook.write(os);
} catch (IOException e) {
e.printStackTrace();
}
}
获取当年1月1号~当前时间的数据
private static List<TimeDay> getStudentInfo() throws Exception {
List<TimeDay> TimeDays = new ArrayList<TimeDay>();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String startDate = getCurrYearFirst()+"-01-01";
String currenDate = sdf.format(new Date());
List<String> allWeekly2 = getAllWeekly2(startDate, currenDate);
if(allWeekly2 != null && allWeekly2.size() > 0){
for (int aa = 0;aa < allWeekly2.size();aa++){
TimeDays.add(new TimeDay(allWeekly2.get(aa)));
}
}
return TimeDays;
}
获取当年的第一天日期
public static String getCurrYearFirst(){
Calendar currCal=Calendar.getInstance();
int currentYear = currCal.get(Calendar.YEAR);
return String.valueOf(currentYear);
}
获取起始时间startDate 至 结束时间endDate 时间段中所有的为星期五的数据（没有排除周末和节假日为周五的情况）
public static List<String> getAllWeekly2(String startDate, String endDate) throws Exception {
// 获取两个日期之间的所有日期
DateFormat format = new SimpleDateFormat("yyyy-MM-dd");
Calendar calBegin = Calendar.getInstance();
calBegin.setTime(format.parse(startDate));
Calendar calEnd = Calendar.getInstance();
calEnd.setTime(format.parse(endDate));
List<String> Datelist = new ArrayList<String>();
while (format.parse(endDate).after(calBegin.getTime())) {
calBegin.add(Calendar.DAY_OF_MONTH, 1);
Date date = calBegin.getTime();
SimpleDateFormat dateFm = new SimpleDateFormat("EEEE");
String currSun = dateFm.format(date);
if (currSun.equals("星期五")) {
Calendar calendar = Calendar.getInstance();
calendar.setTime(date);
DateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
String format1 = sdf.format(date);
Datelist.add(format1);
}
}
return Datelist;
}
这里记录一下主要的方法，这里就不介绍导出Excel的模板。
