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);
