本段程式碼是獲得今日凌晨和明日凌晨兩個時間：

Date date=new Date();
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String time=df.format(date);
System.err.println(time);// 當前時間
String[] at = time.split(" ");
time = at[0] + " 00:00:00";
getParames().put("beginTime", time);
Calendar cal = Calendar.getInstance();  
 

try {
    cal.setTime(df.parse(time));
} catch (ParseException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}  
cal.add(Calendar.DAY_OF_YEAR, +1);  
String nextDate_1 = df.format(cal.getTime());  
System.err.println(nextDate_1);// 明日時間
getParames().put("endTime", nextDate_1);
