3.获取某天的最大时间和最小时间，使用Calendar 

 1 if (taxTraySummaryListDTO.getStartDate() != null) {
 2             Calendar cal = Calendar.getInstance();
 3             cal.setTime(taxTraySummaryListDTO.getStartDate());
 4             cal.set(Calendar.HOUR_OF_DAY, 0);
 5             cal.set(Calendar.MINUTE, 0);
 6             cal.set(Calendar.SECOND, 0);
 7             cal.set(Calendar.MILLISECOND, 0);
 8             taxTraySummaryListDTO.setStartDate(cal.getTime());
 9         }
10         if (taxTraySummaryListDTO.getEndDate() != null) {
11             Calendar cal = Calendar.getInstance();
12             cal.setTime(taxTraySummaryListDTO.getEndDate());
13             cal.set(Calendar.HOUR_OF_DAY, 23);
14             cal.set(Calendar.MINUTE, 59);
15             cal.set(Calendar.SECOND, 59);
16             taxTraySummaryListDTO.setEndDate(cal.getTime());
17         }
