采集怀俄明大学探空数据-Java代码

代码：

Calendar c = Calendar.getInstance();//可以对每个时间域单独修改

Integer year = c.get(Calendar.YEAR);
Integer month = c.get(Calendar.MONTH)+1;
Integer date = c.get(Calendar.DATE);
Integer hour = c.get(Calendar.HOUR_OF_DAY);
String dateCode = String.format("%02d", date);
if(hour <= 12){
	dateCode += "00";
}else {
	dateCode += "12";
}
//区县地图编号
String stnm = "51644";
//数据日期拼接
StringBuffer sb = new StringBuffer();
sb.append(year);
sb.append(month);
sb.append(dateCode);

//查询当前数据时间段类，是否已经有数据,如果有数据直接返回
List<DynaBean> dataList = this.queryUrlData(sb.toString(), stnm);
