// 利用Apache lang包快速获取凌晨0点0分0秒,23点59分59秒字符串
System.out.println(DateFormatUtils.format(new Date(), “yyyy-MM-dd 00:00:00”));
System.out.println(DateFormatUtils.format(new Date(), “yyyy-MM-dd 23:59:59”));
// 获取当天凌晨0点0分0秒Date
Calendar calendar1 = Calendar.getInstance();
calendar1.set(calendar1.get(Calendar.YEAR), calendar1.get(Calendar.MONTH), calendar1.get(Calendar.DAY_OF_MONTH),
0, 0, 0);
Date beginOfDate = calendar1.getTime();
System.out.println(beginOfDate);
// 获取当天23点59分59秒Date
Calendar calendar2 = Calendar.getInstance();
calendar2.set(calendar2.get(Calendar.YEAR), calendar2.get(Calendar.MONTH), calendar2.get(Calendar.DAY_OF_MONTH),
23, 59, 59);
Date endOfDate = calendar2.getTime();
System.out.println(endOfDate);
依次输出结果:
2016-05-24 00:00:00
2016-05-24 23:59:59
Tue May 24 00:00:00 CST 2016
Tue May 24 23:59:59 CST 2016
