JSP頁(yè)面獲取系統(tǒng)當(dāng)前時(shí)間1:import java.util.*; int y,m,d,h,mm; Calendar c = Calendar.getInstance(); y = c.get(Calendar.YEAR); //年 m = c.get(Calendar.MONTH) + 1; //月 d = c.get(Calendar.DAY_OF_MONTH); //日 h = c.get(Calendar.HOUR); //時(shí)（HOUR——十二小時(shí)制；HOUR_OF_DAY——二十四小時(shí)制） mm = c.get(Calendar.MINUTE); //分 2: java.util.Date d = new java.util.Date(); java.text.SimpleDateFormat dformat = new java.text.SimpleDateFormat("yyyy-MM-dd"); String datetime = dformat.format(d); System.out.println(datetime); 3: import java.util.*; import java.text.*; Date now = new Date(); DateFormat defaultFormat = DateFormat.getDateInstance(); DateFormat shortFormat = DateFormat.getDateInstance(DateFormat.SHORT); DateFormat mediumFormat = DateFormat.getDateInstance(DateFormat.MEDIUM); DateFormat longFormat = DateFormat.getDateInstance(DateFormat.LONG); DateFormat fullFormat = DateFormat.getDateInstance(DateFormat.FULL); String defaultDate = defaultFormat.format(now); String shortDate = shortFormat.format(now); String mediumDate = mediumFormat.format(now); String longDate = longFormat.format(now); String fullDate = fullFormat.format(now); System.out.println("(Default) Today :" + defaultDate); System.out.println("(SHORT) Today : " + shortDate); System.out.println("(MEDIUM) Today :" + mediumDate); System.out.println("(LONG) Today : " + longDate); System.out.println("(FULL) Today : " + fullDate); 4. <% java.util.Date now=new java.util.Date(); out.println(now); %> 如果只要年月日,可以用subString()截取. 或者用這個(gè) String time=new SimpleDateFormat("yyyy-MM-dd").format(Calendar.getInstance().getTime); 5. Date currentTime = new Date(); SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd"); String dateString = formatter.format(currentTime); dataString 的格式就是2007-03-08這類(lèi)型 |
