产生时间字符串组

根据当前时间生成一组间隔时间。　在SQL中通过字符时间去查询，避免跟时区有关联

SimpleDateFormat formatmm =new SimpleDateFormat("mm");
       SimpleDateFormat format =new SimpleDateFormat("yyyy-MM-dd HH");
       SimpleDateFormat formatfull =new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
       Date date = new Date();
       String minutes = formatmm.format( date) ;
       String newMinutes = "00";
       if ( Integer.parseInt(minutes)>30)
           newMinutes = "30";
//       String newMinutes = minutes.substring(0,1)+0 ;
       System.out.println ( newMinutes )        ;
       String prefixDate = format.format(date);
       String newStartDate = prefixDate + ":"+newMinutes+":00";
       System.out.println( prefixDate );
       int range=12;//hours
       int groupTime = 30;//minutes;
       Date curreentDate = null;
       List<String> starts = new ArrayList<String>();
       List<String> ends = new ArrayList<String>();
       try {
           curreentDate = formatfull.parse( newStartDate);
           int totalMinutes = range*60;
           int i=0;
           while(totalMinutes>0){
               long currentMillSeconds = curreentDate.getTime();
               long endMillSeconds = currentMillSeconds-i*groupTime*60*1000;
               long beginMillSeconds = currentMillSeconds - (i+1)*groupTime*60*1000;
               starts.add(formatfull.format( beginMillSeconds ));
               ends.add(formatfull.format( endMillSeconds ));
               totalMinutes=totalMinutes-groupTime;
               i++;
           }
           for(int j=starts.size()-1;j>0;j--){
               System.out.println( starts.get(j) + " -- "+ends.get(j));
           }
       } catch (ParseException e) {
           e.printStackTrace();
       }
