java将时间用毫秒表示

java获取当前时间精确到毫秒

new SimpleDateFormat("yyyyMMddHHmmssSSS") .format(new Date() );

方法2：

Calendar Cld = Calendar.getInstance();

int YY = Cld.get(Calendar.YEAR) ;

int MM = Cld.get(Calendar.MONTH)+1;

int DD = Cld.get(Calendar.DATE);

int HH = Cld.get(Calendar.HOUR_OF_DAY);

int mm = Cld.get(Calendar.MINUTE);

int SS = Cld.get(Calendar.SECOND);

int MI = Cld.get(Calendar.MILLISECOND);

String curTime = YY + MM + DD + HH + mm + SS + MI;

Calendar cal = Calendar.getInstance();

java.util.Date date = cal.getTime();

SimpleDateFormat sdFormat = new SimpleDateFormat("yyyyMMddhhmmssSSS");

String myTime = sdFormat.format(currentTime);
